Output Parameters In SQL Sp's

Feb 26, 2008

Hi everyone, can anyone help me please

I have a stored procedure that works quite well and returns one of the following codes, 1 2 3 or 4 which is dependant on business criteria.  This sp works well and satsisfies all the criteria etc.

I am calling this SP in asp.net (c#) like this

        using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["blah"].ConnectionString))
        {            int? intSQLCheck = null;


            con.Open();
            SqlCommand cmd = new SqlCommand("check_values", con);
            cmd.CommandType = CommandType.StoredProcedure;

            cmd.Parameters.Add(new SqlParameter("@param_clothing_id", this.DropDownList2.SelectedValue.ToString()));
            cmd.Parameters.Add(new SqlParameter("@empNo", this.DropDownList1.SelectedValue.ToString()));
            cmd.Parameters.Add(new SqlParameter("@createdBy", this.txtEmpNo.Text.ToString()));
            cmd.Parameters.Add(new SqlParameter("@price", this.txtPrice.Text));
            cmd.Parameters.Add(new SqlParameter("@qty", this.txtQty.Text));
            //cmd.Parameters.Add(new SqlParameter("@returnValue", 0));
            cmd.Parameters.Add(new SqlParameter("@returnVal", 99));
            cmd.Parameters["@returnVal"].Direction = ParameterDirection.Output;


            cmd.ExecuteNonQuery();

 

What I would like to do know is use a variable intSqlCheck to hold the return value from the SP (and then do some processing of business logic using the variable)

Any ideas anyone please

Transact SQL :: Generic Store Procedure Call Without Output Parameters But Catching Output

Sep 21, 2015

Inside some TSQL programmable object (a SP/or a query in Management Studio)I have a parameter containing the name of a StoreProcedure+The required Argument for these SP. (for example it's between the brackets [])

EX1 : @SPToCall : [sp_ChooseTypeOfResult 'Water type']
EX2 : @SPToCall : [sp_ChooseTypeOfXMLResult 'TABLE type', 'NODE XML']
EX3 : @SPToCall : [sp_GetSomeResult]

I can't change thoses SP, (and i don't have a nice output param to cach, as i would need to change the SP Definition)All these SP 'return' a 'select' of 1 record the same datatype ie: NVARCHAR. Unfortunately there is no output param (it would have been so easy otherwise. So I am working on something like this but I 'can't find anything working

DECLARE @myFinalVarFilledWithCachedOutput 
NVARCHAR(MAX);
DECLARE @SPToCall NVARCHAR(MAX) = N'sp_ChooseTypeOfXMLResult
''TABLE type'', ''NODE XML'';'
DECLARE @paramsDefintion = N'@CatchedOutput NVARCHAR(MAX) OUTPUT'

[code]...

ADO.NET 2-VB 2005 Express Form1:Printing Output Of Returned Data/Parameters From The Parameters Collection Of A Stored Procedure

Mar 12, 2008

Hi all,
From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:


Imports System.Data

Imports System.Data.SqlClient

Imports System.Data.SqlDbType

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim PubsConn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;integrated security=sspi;" & "initial Catalog=pubs;")

Dim testCMD As SqlCommand = New SqlCommand("TestProcedure", PubsConn)

testCMD.CommandType = CommandType.StoredProcedure

Dim RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)

RetValue.Direction = ParameterDirection.ReturnValue

Dim auIDIN As SqlParameter = testCMD.Parameters.Add("@au_idIN", SqlDbType.VarChar, 11)

auIDIN.Direction = ParameterDirection.Input

Dim NumTitles As SqlParameter = testCMD.Parameters.Add("@numtitlesout", SqlDbType.Int)

NumTitles.Direction = ParameterDirection.Output

auIDIN.Value = "213-46-8915"

PubsConn.Open()

Dim myReader As SqlDataReader = testCMD.ExecuteReader()

Console.WriteLine("Book Titles for this Author:")

Do While myReader.Read

Console.WriteLine("{0}", myReader.GetString(2))

Loop

myReader.Close()

Console.WriteLine("Return Value: " & (RetValue.Value))

Console.WriteLine("Number of Records: " & (NumTitles.Value))

End Sub

End Class

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The original article uses the code statements in pink for the Console Applcation of VB.NET. I do not know how to print out the output of ("Book Titles for this Author:"), ("{0}", myReader.GetString(2)), ("Return Value: " & (RetValue.Value)) and ("Number of Records: " & (NumTitles.Value)) in the Windows Application Form1 of my VB 2005 Express. Please help and advise.

Thanks in advance,

SQL Output Parameters

Mar 5, 2008

 Hi, I have a form with a detailsview and a sqldatasource.  The sqldatasource uses a stored procedure as the select command.  This stored procedure requires 2 input parameters and returns 3 output parameters. A button on the form is enabled or disabled depending on the value of the output parameters. When the page loads, I get a "Object reference not set to an instance of an object" message, caused by the null value of an output parameter.  SQL Profiler shows that the input parameters are correct, and if I run the stored procedure directly, it's okay. Can anybody tell me why I wouldn't get the output parameters? Thanks,Neil

Sql Output Parameters

Oct 16, 2007

I am new to SQL and trying to work out how to do this

i have a table called projectAllocationLog with 4 fields, there can be many users of any particular project, ie
ID,projectID, User, Date
4 5000, 6, 10/02/2007
3 5000, 12, 08/07/2005
2 5004, 13, 08/05/2003
1 5000, 14, 04/05/2001

I want to write a stored proceedure that I can pass in the projectID, and return the most current user, this will always be the user with the highest ID for the project

ie for project 5000 it will be user 6

I was thinking along the lines of for each project select the top 1 from the table. where I can pass in the projectID, and pass out the ID field of the table. i am just not sure how to start this.

Any help would be appreciated.

Jul 31, 2007

I am trying to select multiple values from the row with the max id,and output them within my stored procedure.

I have at least 8other outputs I will be setting and would like this to work moreefficiently than setting each individually... if possible.set @outmtd = (select outmtd from mytable where IDnum = (select(max(IDnum)) from mytable))set @outytd = (select outytd from mytable where IDnum = (select(max(IDnum)) from mytable))Thanks for any help you can giveMatt

Output Parameters, Cookies And C#

Sep 9, 2004

Hello, i got this working using vb.net but becuase I'm learning asp.net I thought it would be a ggood idea to replicate the same function using C# as well1

The problem is I receive an output parameter through a stored procedure which is the users id.

I want to add this to a cookie as I know I'll be using it again and again, but the error I keep getting is cannot cxonvert type 'string' to type 'int'.

I've tried using conversion functions to make the value returned into an int value but I had no success!

I did this -

int id = (int)mycommand.Parameters["@id"].Value;

and then try to save that to the cookie but the error keeps appearing, I've also tried using the parse and ToInt32 function but the same/similar problems - any ideas?

Thanks

SqlDataReader Or Output Parameters?

Oct 10, 2005

Hi all,Is there a data transfer difference between returning a datareader that only has one row or using output parameters?  For instance, I have a login page that shows the last login, member since, display level, number of file views, etc.  Currently I am returning a datareader that reads one row and assigns this data to labels.  But would it be quicker to use OUTPUT parameters instead of using a dataread and just get the values from the command object?ThanksJosh

SP: Default Value For Output Parameters

Feb 8, 2005

When I call a proc with one input parameter and two output parameters, (all the three parameters having defaults in the proc), I was expecting to see these values defaulted to in the proc. But apparently, this not the case. Could someone tell me what am I doing wrong here? Appreciate your time.

USE Pubs
GO

CREATE PROCEDURE dbo.MyTestProc
(@InputParamVARCHAR(30) = 'Input',
@OutPutParam1VARCHAR(30) = 'OutputParam1' OUTPUT,
@OutPutParam2VARCHAR(30) = 'OuputParam2' OUTPUT)
AS
BEGIN
SELECT @InputParam, @OutPutParam1, @OutPutParam2
END
GO

-- Call to the proc

DECLARE @I1VARCHAR(30)
DECLARE @P1VARCHAR(30)
DECLARE @P2VARCHAR(30)

SET@I1 = 'PassedInput'

String Output Parameters

Feb 23, 2008

Hi can any one explain why when I specify an outparameter as a string I only get back the first letter of the string when I call the procedure from .net?

my procedure is...

ALTER PROCEDURE dbo.UpdateUserPACSPASDetails
@UserGUID uniqueidentifier,
@UserPACSName varchar(32),
@PASName varchar(32),
@UserPACSPassword varchar(95),
@UserPACSPasswordIV varchar(95),
@UserFriendlyName varchar(32),
@Message varchar(32) OUTPUT,
@MessageNumber int OUTPUT

AS

SET NOCOUNT ON

DECLARE @tmpGUID as uniqueidentifier /*stores the temp guid from the function */
DECLARE @ReturnDomainName as varchar(32) /*stores the tmp domainname of the user who has the PACS name */

SET @Message=CAST('' as varchar(32))
SET @MessageNumber= 0

/* first check if PACS user name already exists or not */
SET @tmpGUID = dbo.fncFindPACSName(@UserPACSName)

IF @tmpGUID IS NOT NULL /* if the value is null the the PACSusername doesn't exist
if its not null then does the current user already own that PACSUserName? */
BEGIN

/*if the users ids are different then another user already has the PACS name */
IF @tmpGUID<>@UserGUID
BEGIN
SELECT @ReturnDomainName = UserDomainName FROM tblUsers WHERE UserGUID=@tmpGUID
SET @Message=@ReturnDomainName
SET @MessageNumber = 1
RETURN

END
END

/*now check the PAS name to see if it exists or is already in use by someone else
first check if PACS user name already exists or not */
SET @tmpGUID = dbo.fncFindPASName(@PASName)

IF @tmpGUID IS NOT NULL /* if the value is null the the PACSusername doesn't exist
if its not null then does the current user already own that PACSUserName? */
BEGIN

/*if the users ids are different then another user already has the PACS name */
IF @tmpGUID<>@UserGUID
BEGIN
SELECT @ReturnDomainName = UserDomainName FROM tblUsers WHERE UserGUID=@tmpGUID
SET @Message=@ReturnDomainName
SET @MessageNumber = 2
RETURN

END
END




UPDATE tblUsers
SET UserPACSName=@UserPACSName,UserPACSPassword=@UserPACSPassword,
UserPACSPasswordIV=@UserPACSPasswordIV, PASName=@PASName, UserFriendlyName=@UserFriendlyName

WHERE UserGUID=@UserGUID

SET @Message=CAST('' as varchar(32))
SET @MessageNumber=3

RETURN

I call this proc via a vb.net program using a command.executenonquery and then look at the parameter.

For some reason I only get the first letter of the string back! i.e. if the string is LSDNET/nik I get 'L'.

If I run the proc from visual studio step in to procecure it works fine!

the vb I'm using is... (the createaddparameter simply creates a bunch of parameters to add to a command -with the specified names and dbtypes).

I'm obviously missing a trick but what it is I can't see.
I seem to be able to pass all other data types back easily!

Dim LoadUserCommand As New SqlCommand

'create add command
Dim CreateAddParameter() As String = {"@UserGUID", _
"@UserPACSName", "@PASName", "@UserPACSPassword", _
"@UserPACSPasswordIV", "@UserFriendlyName", "@Message", "@MessageNumber"}
Dim UpdateDBTypes() As DbType = {DbType.Guid, DbType.StringFixedLength, DbType.StringFixedLength, DbType.StringFixedLength, _
DbType.StringFixedLength, DbType.StringFixedLength, DbType.StringFixedLength, DbType.Int32}


LoadUserCommand = lclSQLHelper.CreateOLEDBCommand("UpdateUserPACSPASDetails", CreateAddParameter, UpdateDBTypes, lclDBConn.DBConnection)

LoadUserCommand.Parameters(6).Direction = ParameterDirection.Output
LoadUserCommand.Parameters(7).Direction = ParameterDirection.Output

'update the data in the data table in the database

LoadUserCommand.Parameters(0).Value = lclUser.UserGUID
LoadUserCommand.Parameters(1).Value = lclUser.UserPACSName
LoadUserCommand.Parameters(2).Value = lclUser.UserPASName
LoadUserCommand.Parameters(3).Value = lclUser.UserPACSPassword
LoadUserCommand.Parameters(4).Value = lclUser.PACSPasswordIV
LoadUserCommand.Parameters(5).Value = lclUser.UserFriendlyName
LoadUserCommand.Parameters(6).Value = ""
LoadUserCommand.Parameters(7).Value = 0

Try

Dim lclRet As Integer = LoadUserCommand.ExecuteNonQuery()

Dim tmpDomainName As String
tmpDomainName = LoadUserCommand.Parameters(6).Value.ToString 'read the name back

Dim tmpMsgNumber = LoadUserCommand.Parameters(7).Value 'read the message number back

Select Case tmpMsgNumber 'not written yet as I haven't got this far!!!
Case 1 'pacs username already exists
Case 2 'pas username already exists
Case 3 'execute fine and all names updated



End Select

Output Multivalue Parameters

Jun 16, 2006

I'm trying to output all the values selected through a multivalue parameter, but I am having difficulties. In the text box, the parameter contains only four member functions (value, label, count, ismultivalue). However, to output a value or label for the parameter you need to specify an index in the form of:

Parameters!Names.Value(0)

Ideally, I would like to be able to obtain all these values with a function call, but it doesn't look like there is one. Any ideas of how to get all the values?

Thank you!!

How Do I Retrieve Results Of The Output Parameters??

Feb 17, 2008

I am able to perform my Stored Procedure, but I can't figure out how to get access to the OUTPUT parameters!Here is my code:   Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)

Dim mySqlDataSource As SqlDataSource = New SqlDataSource

mySqlDataSource.InsertCommandType = SqlDataSourceCommandType.StoredProcedure

Output Parameters And Select Statements

Mar 17, 2004

Hi,

thanks for reading!

Here is my problem: I have a strored procedure that inserts some records

into one table and then selects some records from another table at the end.

The stored procedure takes several parameters, first one of them is marked as

OUTPUT. I'm using it to return an id of the inserted record. The procedure is called from asp.net code with first parameter set as ParameterDirection.InputOutput (tried with just Output as well). Now for the problem: if the the select statement at the end returns 0 records everything works and i my first parameter contains the @@IDENTITY value from the insert statement like it is supposed to.

If the select statement at the end returns 1 or more records my output parameter is not updated at all and contains the same value as before the procedure was run. All the records are inserted correctly.

if i try to return the @@identity as a plain select statement instead of through the parameter
i get System.DBNull.

I hope you can shed some light on this for me. Here is my stored procedure:



CREATE PROCEDURE cwSaveProductInquiry
@inquiryId int OUTPUT,
@libraryName nvarchar(500),
@contactName nvarchar(200),
@address nvarchar(100),
@city nvarchar(50),
@state nvarchar(3),
@zip nvarchar(10),
@phone nvarchar(50),
@email nvarchar(100),
@comment nvarchar(3000),
@productIds nvarchar(2000)

AS

INSERT INTO INQUIRY (LibraryName, ContactName, Address, City, State, Zip, Phone, Email, Comment) VALUES(@libraryName, @contactName, @address, @city, @state, @zip, @phone, @email,@comment)


--i tried including this statement at the end as well but that did not do the

--trick either

select @inquiryId=@@IDENTITY FROM INQUIRY





set nocount on
declare @separator_position int -- This is used to locate each separator character
declare @objectId varchar(200) -- this holds each array value as it is returned

if(@productIds is not null)
begin
while patindex('%,%' , @productIds) <> 0
begin
select @separator_position = patindex('%,%' , @productIds)
select @objectId= left(@productIds, @separator_position - 1)
INSERT INTO PRODUCT_INQUIRY_LOOKUP (ProductId,InquiryId) VALUES(@objectId, @inquiryId)
select @productIds = stuff(@productIds, 1, @separator_position, '')
end
end
set nocount off

Select Distinct Email from vPRODUCT_CONTACT WHERE ProductId in
(Select ProductId From Product_Inquiry_Lookup Where InquiryId=@inquiryId)

GO

Stored Procedure Output Parameters

Aug 3, 2004

Hi

I've an existing SQL 2000 Stored Procedure that return data in many (~20) output parameters.

I'm starting to use it in a .Net c# application and it seems to insist that I setup all the output parameters:
SqlParameter param = cmd.Parameters.Add("@BackgroundColour",SqlDbType.TinyInt);
param.Direction=ParameterDirection.Output;
even if I only need the value of a single one.
Is this right? Is there a way to avoid coding every one every time?

Using SqlDatASource Programmatically - Output Parameters

May 13, 2006

I am using SqlDataSource programmatically in my data access layer - mainly for convenience but it does generally work fine with no obvious performance issues.
The problem I have is with getting back an output parameter. I have an insert-type stored procedure (in Sql Server 2005) operating on a table with an identity column as the primary key:
ALTER PROCEDURE [dbo].[InsertAlbum](@ArtistID int, @Title nvarchar(70), @NewID int OUTPUT)ASDECLARE @err intINSERT INTO dbo.ALBUMS (ARTISTID, TITLE)VALUES (@ArtistID, @Title)SELECT @err = @@error IF @err <> 0 RETURN @errSET @NewID = SCOPE_IDENTITY()
This works fine when run from Sql Server Management Studio and @NewID has the correct value.
My data access code is roughly as follows:
dsrc = New SqlDataSource()dsrc.ConnectionString = ConnectionStringdsrc.InsertCommand = "InsertAlbum"dsrc.InsertCommandType = SqlDataSourceCommandType.StoredProcedureDim parms As ParameterCollection = dsrc.InsertParametersDim newid As IntegerAddParameter(parms, "ArtistID", TypeCode.Int32, ParameterDirection.Input, 0, album.ArtistID)AddParameter(parms, "Title", TypeCode.String, ParameterDirection.Input, 0, album.Title)Dim p As New Parameter("NewID", TypeCode.Int32)p.Direction = ParameterDirection.Outputparms.Add(p)Try   Dim rv As Integer = dsrc.Insert()   newid = parms("NewID")   Return newidCatch ex As Exception   Return -1End Try
The row is inserted into the database, but however I try to define and add the NewID parameter it never has a value.
Has anyone tried to do this and can tell me what I am doing wrong?
Jon

@@Rowcount Or Output Parameters Error

Dec 12, 2005

I have the following stored procedure working with an Access 2000 front end. The output parameters returned to Access are both Null when the record is successfully updated (ie when @@Rowcount = 1), but the correct parameters are returned when the update fails. I'm a bit new to using output parameters, but I have them working perfectly with an insert sproc, and they look basically the same. What bonehead error have I made here? The fact that the record is updated indicates to me that the Commit Trans line is being executed, so why aren't the 2 output parameters set?

TIA

EDIT: Solved, sort of. I found that dropping the "@ResNum +" from "@ResNum + ' Updated'" resolved the problem (@ResNum is an input parameter). This implies that the variable lost its value between the SQL statement and the If/Then, since the SQL correctly updates only the appropriate record from the WHERE clause. Is this supposed to happen? I looked in BOL, and if it's addressed there I missed it.

CREATE PROCEDURE [procResUpdate]

Various input parameters here,

@RetCode as int Output, @RetResNum as nvarchar(15) Output

AS

Declare @RowCounter int

Begin Tran

UPDATE tblReservations
SET Various set statements here, LastModified = @LastModified + 1
WHERE ResNum = @ResNum AND LastModified = @LastModified

SELECT @RowCounter = @@ROWCOUNT

If @RowCounter = 1
Begin
Commit Tran
Select @RetCode = 1
Select @RetResNum = @ResNum + ' Updated'
End
Else
Begin
Rollback Tran
Select @RetCode = 0
Select @RetResNum = 'Update Failed'
End

The Dynamic SQL Statements With Output Parameters

Nov 15, 2005

The dynamic SQL statements with output parameters, unfortunately, in the documentation are not described.
À) Simple example of the dynamic SQL statement with output parameters

-- dynamic SQL statements expects parameter of type 'ntext/nchar/nvarchar'.
declare @SQLString nvarchar(4000), @ParmDefinition nvarchar(4000)
-- the third parameter passed in the dynamic statement as by output, returns the length of
-- the hypotenuses of a right triangle, two first parameters are lengths of legs of a triangle
declare @nHypotenuse float
select @SQLString = 'select @nHypotenuse = sqrt(square(@nLeg1_of_a_triangle)+square(@nLeg2_of_a_triangle))',
@ParmDefinition = '@nLeg1_of_a_triangle float, @nLeg2_of_a_triangle float, @nHypotenuse float out'
-- we call the dynamic statement in such a way
exec sp_executesql @SQLString, @ParmDefinition, @nLeg1_of_a_triangle = 3.0, @nLeg2_of_a_triangle = 4.0, @nHypotenuse = @nHypotenuse out
-- or in such a way
exec sp_executesql @SQLString, @ParmDefinition, 3.0, 4.0, @nHypotenuse out
select @nHypotenuse -- Displays 5.0


B) Example of usage of the dynamic statement with output parameter and the function GETALLWORDS.
The following stored procedure get all words from a field of the type text or ntext, the word length should not exceed 4000 characters.

CREATE PROCEDURE SP_GETALLWORDSFROMTEXT
@TableName sysname, @FieldIdName sysname, @FieldIdValue sql_variant, @FieldTextName sysname, @cDelimiters nvarchar(256) = NULL
AS
-- this Stored procedure inserts the words from a text field into the table.
-- WORDNUM int – Sequence number of a word
-- WORD nvarchar(4000) – the word
-- STARTOFWORD int – position in the text field, with which the word starts
-- LENGTHOFWORD smallint – length of the word
-- Parameters
-- @TableName name of the table with the text or ntext field
-- @FieldIdName name of Id field
-- @FieldIdValue value of Id field
-- @FieldTextName name of field text or ntext
-- @cDelimiters Specifies one or more optional characters used to separate words in the text field
begin
set nocount on

declare @k int, @wordcount int, @nBegSubString int, @nEndSubString int, @nEndString int, @divisor tinyint, @flag bit, @RetTable bit,
@cString nvarchar(4000), @TypeField varchar(13), @SQLString nvarchar(4000), @ParmDefinition nvarchar(500), @nBegSubString1 smallint, @nEndSubString1 smallint
select @TableName = object_name(object_id(lower(ltrim(rtrim(@TableName))))), @FieldIdName = lower(ltrim(rtrim(@FieldIdName))), @FieldTextName = lower(ltrim(rtrim(@FieldTextName))),
@cDelimiters = isnull(@cDelimiters, nchar(32)+nchar(9)+nchar(10)+nchar(13)), -- if no break string is specified, the function uses spaces, tabs, carriage return and line feed to delimit words.
@nBegSubString = 1, @nEndSubString = 4000, @flag = 0, @RetTable = 0, @wordcount = 0

-- If the temporary table is not created in the calling procedure, we create the temporary table
if object_id( 'tempdb..#GETALLWORDSFROMTEXT') is null
begin
create table #GETALLWORDSFROMTEXT (WORDNUM int, WORD nvarchar(4000), STARTOFWORD int, LENGTHOFWORD smallint)
select @RetTable = 1
end
-- we use the dynamic SQL statement to receive the exact name of text field
-- as we can write names of fields by a call of the given stored procedure in the arbitrary register
-- in the string of parameters definition @ParmDefinition we use a keyword output
-- and by a call of the dynamic SQL statement exec sp_executesql @SQLString, @ParmDefinition, @FieldTextName = @FieldTextName output
-- Also we use a keyword output for definite before parameter
select @SQLString = 'select @FieldTextName = name from syscolumns where id = OBJECT_ID('''+ @TableName+''') and lower(name) = '''+@FieldTextName+''''
select @ParmDefinition = '@FieldTextName sysname output'
exec sp_executesql @SQLString, @ParmDefinition, @FieldTextName = @FieldTextName output

-- we use the dynamic SQL statement to receive the exact name of Id field
select @SQLString = 'select @FieldIdName = name from syscolumns where id = OBJECT_ID('''+ @TableName+''') and lower(name) = '''+@FieldIdName+''''
select @ParmDefinition = '@FieldIdName sysname output'
exec sp_executesql @SQLString, @ParmDefinition, @FieldIdName = @FieldIdName output

-- we use the dynamic SQL statement to receive the type of field (text or ntext)
select @SQLString = 'select @TypeField = name from systypes where xtype = any ( select xtype from syscolumns where id = OBJECT_ID('''+ @TableName+''') and lower(name) = '''+@FieldTextName+''')'
select @ParmDefinition = '@TypeField varchar(13) output'
exec sp_executesql @SQLString, @ParmDefinition, @TypeField = @TypeField output

select @divisor = case @TypeField when 'ntext' then 2 else 1 end -- 2 for unicode

-- we use the dynamic SQL statement to receive a length of the text field
select @SQLString = 'select @nEndString = 1 + datalength('+ @FieldTextName+')/'+cast( @divisor as nchar(1)) +' from '+@TableName +' where '+ @FieldIdName+' = ' +cast(@FieldIdValue as nchar(50))

Stored Procedure And Output Parameters

Mar 23, 2007

Hi,

I hope someone can help.

I've written a stored procedure that returns a value via an output parameter.

I'm calling the stored procedure in an sql session is a loop, and it passes the value back correctly the first time, but all subsequent calls the output parameter appears to have the same value. I believe that I'm making some very basic mistake, but I can't work it out.

Here's how I'm calling the stored procedure several times
begin
declare @instrumentid int
exec GetInstrumentId 'OFX,AUDCHF,p,1,2007-03-20 16:54:21.843,2007-06-20,100.1', @instrumentid output;
select @instrumentid
exec GetInstrumentId 'OFX,AUDUSD,c,2,2007-03-20 16:54:21.843,2007-06-20,100.2', @instrumentid output;
select @instrumentid
exec GetInstrumentId 'OFX,AUDCHF,p,3,2007-03-20 16:54:21.843,2007-06-20,100.3', @instrumentid output;
select @instrumentid
end

And this is the start of the stored procedure

Create PROCEDURE [dbo].[GetInstrumentId]
(@Ticket varchar(250), @InstrumentId int output)
AS


If I call the stored procedure once it gives the corect output, if I call it several times the output parameter (@instrumentid ) never changes.

OUT And OUTPUT - Stored Procedure Parameters.

Nov 19, 2006

Hi All,

The following is a code snippit. My main interests are the OUT and OUTPUT parameter keywords. One returns a single value, and the other seemingly a resultset. OUTPUT returns a single value, however OUT seems to return a list of values. Could I please get this confirmed?

Also, I cannot see how the value being returned by OUT is being iterated...

Any help on the obove two matters is appreciated.

Thank You

Chris

Sp_executesql And NVARCHAR OUTPUT Parameters

Oct 24, 2007

Hi All,

We seem to have an problem with using sp_executesql and retrieving back NVARCHAR output parameters. We are trying to dynamically set string values using string templates ( for English and other languages that require using NVARCHAR parameters ). A test case is:

DECLARE @Description NVARCHAR(400)
DECLARE @Template NVARCHAR(400)

SET @Template = N'''ПричинÑ?ет ''' -- this string is in Russian
SET @Template = N'SET @DescriptionOUT = ' + @Template

EXEC sp_executesql @Template, N'@DescriptionOUT NVARCHAR(4000) OUTPUT', @DescriptionOUT = @Description OUTPUT

PRINT @Description

If you print @Description it appears as: ????????? instead of the Russian text.

Any thoughts or ideas on why this isn't working as the BOL indicate that everything should correctly handle NVARCHARs?

Thanks.

Robert

How To Extract Output Parameters From A Stored Procedure.

Jan 25, 2008

I am stuck on how to syntactically retrieve an output value (@ProdCount) from a stored procedure. The SPROC works fine: the value of @ProdCount appears correctly in the output window. However, I can't retrieve it in the DAL handler (value remains 0). Does anyone have an idea on how to properly extract the return value. TIA for any pointers.SPROC (abridged): ALTER PROCEDURE and_Store_GetProductsByProdCatID_SortPage (@ProdCatID INT,...@ProdCount INT OUTPUT
)

ASSELECT @ProdCount=(SELECT COUNT(*) FROM and_StoreProduct WHERE ProdCatID= @ProdCatID)DECLARE @SQL nvarchar(4000)SET @SQL = 'WITH tmpProd AS ( SELECT ROW_NUMBER() etc.. )SELECT ProdID, etc..FROM tmpProdWHERE Row BETWEEN etc..ORDER BY etc..'

EXECUTE(@SQL)RETURNDAL handler (abridged): Public Overloads Shared Function GetProductListByCatID(ByVal ProdCatID As Integer, ..., ByVal ProdCount As Integer) As List(Of Product) Dim productList As List(Of Product) = New List(Of Product) Try

Some Problems With Output Parameters In Stored Procedures

Jul 6, 2004

I have written a simple C# console application that create my own Stored Procedures
the code is here
----------------------------------------------------------------------------

static void Main(string[] args)
{
SqlConnection cn;
string strSql;
string strConnection;
SqlCommand cmd;
strConnection="server=(local);database=Northwind;integrated security=true;";
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) @counter int OUTPUT AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID SET @counter=@@rowcount";
cn=new SqlConnection(strConnection);
cn.Open();
cmd=new SqlCommand(strSql,cn);
cmd.ExecuteNonQuery();
cn.Close();
Console.WriteLine("Procedure Created!");
}

------------------------------------------------------------------------------------
but it has some errors becuase of my strSql
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) @counter int OUTPUT AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID SET @counter=@@rowcount";
I mean in creating the stored procedure
if i delete the Output parameter from my stored procedure
and my strSql would be somethimg like this
strSql="CREATE PROCEDURE spmahdi @CustomerID nchar(5) AS SELECT OrderID, OrderDate,RequiredDate,ShippedDate FROM Orders WHERE CustomerID = @CustomerID ORDER BY OrderID ";
There will be no errors
I use Visual Studio.NET 2003(full versoin)and MSDE(not Sql Server)
Could someone help me solve this problem?
Thanks and Regards.

Full-Text Search And Output Parameters

Nov 14, 2007

Hi,

I'd like to incorporate search functionality (SQL Server 2005 Full-Text Search) into a web application, so I want to be able to return a paged list of results based on the user's search terms. I already have a parameterized stored procedure that returns a list of products when a category ID is supplied. I modified this procedure to use a different input parameter (@SearchTerms), but I'd still like to return the number of records, as in the original stored procedure.

However, I'm getting this error: Invalid object name 'ProductEntries'.

Here's the original stored procedure:

ALTER PROCEDURE dbo.GetProductsByCategoryID
(
@CategoryID INT,
@PageIndex INT,
@NumRows INT,
@CategoryName VARCHAR(50) OUTPUT,
@CategoryProductCount INT OUTPUT
)
AS

BEGIN
SELECT @CategoryProductCount = (SELECT COUNT(ProductID)
FROM Products
WHERE Products.CategoryID = @CategoryID)
SELECT @CategoryName = (SELECT CategoryName
FROM Categories
WHERE Categories.CategoryID = @CategoryID)

DECLARE @startRowIndex INT;
SET @startRowIndex = (@PageIndex * @NumRows) + 1;

WITH ProductEntries AS (
SELECT ROW_NUMBER() OVER(ORDER BY ProductID) AS Row, ProductID, CategoryID, Description, ProductImage, UnitCost
FROM Products
WHERE CategoryID = @CategoryID
)

SELECT ProductID, CategoryID, Description, ProductImage, UnitCost
FROM ProductEntries
WHERE Row BETWEEN
@startRowIndex AND @startRowIndex + @NumRows - 1

END


And here's the modified one:

ALTER PROCEDURE dbo.GetSearchResults
(
@SearchTerms VARCHAR(200),
@PageIndex INT,
@NumRows INT,
@ProductCount INT OUTPUT
)
AS

BEGIN
SELECT @ProductCount = (SELECT COUNT(ProductID)
FROM ProductEntries)

DECLARE @startRowIndex INT;
SET @startRowIndex = (@PageIndex * @NumRows) + 1;

WITH ProductEntries AS (
SELECT ROW_NUMBER() OVER(ORDER BY ProductID) AS Row, ProductID, CategoryID, Description, ProductImage, UnitCost
FROM CONTAINSTABLE (Products, *, @SearchTerms, 25) AS c, Products p
WHERE c.[KEY] = p.ProductID
)

SELECT ProductID, CategoryID, Description, ProductImage, UnitCost
FROM ProductEntries
WHERE Row BETWEEN
@startRowIndex AND @startRowIndex + @NumRows - 1

END

I thought I might be getting this error because SELECT @ProductCount occurs before the ProductEntries table is created, but when I move that SELECT statement further down, I still get the same error.

How can I get the value of @ProductCount in this scenario so that I can display it in the UI of the web app?

Problem With Output Parameters That Are Varchar And Null

May 30, 2006

I am using version 9.00.2047.00 SP1 of Visual Studio 2005.

Using ADO.NET, I have been unable to get the Execute SQL task to successfully return the value of an output parameter defined as varchar or nvarchar when the value is null. No other data types seem to have this problem, including the sql_variant data type.

Here is the stored procedure I am calling:

create proc spx
@in int = null output,
@vc nvarchar(10) = null output,
@dt datetime = null output
as
select
@in = null,
@vc = null,
@dt = null
return

The variables to which the three output parameters return their values have a data type of Object. The task runs fine when the integer or datetime parameters are used, and the variables can be identified as null using IsDBNull. But as soon as the nvarchar (or varchar) parameter is included, the task fails with this message:

"The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 ("@vc"): Data type 0xE7 has an invalid data length or metadata length."

I have seen a couple of postings that sound similar to this problem, but so far I have found no resolution. Any advice would be much appreciated.

Thanks,

Ron Rice

Deleted Event On Sqldatasource And Output Parameters... Always NULL!!

Apr 18, 2007

I have an event:
Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted
Dim command As SqlClient.SqlCommand
command = e.Command
If command.Parameters("@nReturnCode").Value <> 0 Then
    DROPDEAD()
End If
That  fires from:
<DeleteParameters>
<asp:Parameter Name="nDeletebyId" Type="Int64" />
<asp:Parameter Name="nOtherId" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />
</DeleteParameters>
End Sub
 
When I:
GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)
But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:
ALTER PROCEDURE [dbo].[sp_nDeletebyId]
 @nReturnCode bigint output,
@nReturnId bigint output AS
SET @nReturnCode = 0
SET @nReturnId = 0
And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock.  Has anyone seen this before?  The above sample stored proc did return 0 when executed one the server...
and, BTW, the row is deleted!
