Output Parameter Not Fetched From Dynamic T-SQL Procedure
Sep 9, 2005
I have a STORED PROC for dynamic T-SQL that returns a OUTPUT varaible of typevarchar . This works fine in query analyzer.
But when I try to get values in asp.net page it does not return anything. No execeptions or errors also. Below is the code snippet
HDConn = CommonMethods.BuildConnection();SqlCommand cmd1 = new SqlCommand("GenerateRowids",HDConn);cmd1.CommandType = CommandType.StoredProcedure;// add parameters for Proccmd1.Parameters.Add("@TableName",SqlDbType.VarChar,50).Value= "MetricsMaster";cmd1.Parameters.Add("@ColumnName",SqlDbType.VarChar,50).Value= "MetricId";cmd1.Parameters.Add("@rowidval",SqlDbType.VarChar,30);cmd1.Parameters["@rowidval"].Direction = ParameterDirection.Output;try{cmd1.ExecuteNonQuery();//the below line does not print the valueResponse.Write(cmd1.Parameters["@rowidval"].Value.ToString());}My stored proc looks like :CREATE PROCEDURE dbo.GenerateRowids@TableName varchar(50),@ColumnName varchar(50),@rowidval varchar(30) outputASBegindeclare @sql nvarchar(4000), @Idval varchar(50)
set @sql = N'select left(MAX(' + @ColumnName +') ,1)+ convert(varchar(5),Cast(SUBSTRING((MAX(' +@ColumnName+ ')),2,(len(MAX(' +@ColumnName+ '))))as int)+1) from ' + @TableNameexec sp_executesql @query = @sql,@params = N'@rowidval varchar OUTPUT', @rowidval = @rowidval OUTPUT ENDGO

In my ASP.NET page I use a stored procedure that have a parameter declared as OUTPUT...
however...I do not know how to get this OUTPUT to be stored in a ASP.NET-variable...
this is the sp:
CREATE PROCEDURE spInsertNews
@uidArticleId uniqueidentifier OUTPUT,
@strHeading nvarchar(300),
@strAbstract nvarchar(600),
@strText nvarchar(4000),
@dtDate datetime,
@dtDateStart datetime,
@dtDateStop datetime,
@strAuthor nvarchar(200),
@strAuthorEmail nvarchar(200),
@strKeywords nvarchar(400)
AS
SET @uidArticleId = newid()
INSERT INTO tblArticles
VALUES(@uidArticleId ,@strHeading,@strAbstract,@strText,@dtDate,@dtDateStart,@dtDateStop,@strAuthor,@strAuthorEmail,@strKeywords)
my asp code is something like this:
...
SqlCommand sqlcmdInsertNewsArticle = new SqlCommand(insertCmd, sqlconCon);
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strHeading", SqlDbType.NVarChar, 300));
sqlcmdInsertNewsArticle.Parameters["@strHeading"].Value = strHeading.Text;
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strAbstract", SqlDbType.NVarChar, 600));
sqlcmdInsertNewsArticle.Parameters["@strAbstract"].Value = strAbstract.Text;
sqlcmdInsertNewsArticle.Parameters.Add(new SqlParameter("@strText", SqlDbType.NVarChar, 4000));
sqlcmdInsertNewsArticle.Parameters["@strText"].Value = strText.Text;
...
sqlcmdInsertNewsArticle.Connection.Open();
sqlcmdInsertNewsArticle.ExecuteNonQuery();
sqlcmdInsertNewsArticle.Connection.Close();
How do I do if I want to catch the OUTPUT-parameter (@uidArticleId)?
anyone?

I have two stored procedures one generates an output parameter that I then use in the second stored procedure.
1 Try2 Dim myCommand As New SqlCommand("JP_GetChildren", myConn)3 myCommand.CommandType = Data.CommandType.StoredProcedure4
5 myCommand.CommandType = Data.CommandType.StoredProcedure6 myCommand.Parameters.Add(New SqlParameter("@ParentRule", Data.SqlDbType.NVarChar))7 myCommand.Parameters.Add(New SqlParameter("@PlantID", Data.SqlDbType.NVarChar))8 myCommand.Parameters.Add(New SqlParameter("@New_ReleasingRulePrefix", Data.SqlDbType.NVarChar))9 myCommand.Parameters.Add(New SqlParameter("@New_ReleasingRuleSuffix", Data.SqlDbType.NVarChar))10 myCommand.Parameters.Add(New SqlParameter("@New_PlantID", Data.SqlDbType.NVarChar))11 myCommand.Parameters.Add(New SqlParameter("@New_RuleSetID", Data.SqlDbType.NVarChar))12 myCommand.Parameters.Add(New SqlParameter("@Count", Data.SqlDbType.Int))13 myCommand.Parameters.Add(New SqlParameter("@IDField", Data.SqlDbType.NVarChar))14
15 Dim OParam As New SqlParameter()16 OParam.ParameterName = "@IDFieldOut"
17 OParam.Direction = ParameterDirection.Output18 OParam.SqlDbType = SqlDbType.NVarChar19 myCommand.Parameters.Add(OParam)20
21
22 myCommand.Parameters("@ParentRule").Value = txtParentRule.Text23 myCommand.Parameters("@PlantID").Value = txtStartingPlantID.Text24 myCommand.Parameters("@New_ReleasingRulePrefix").Value = txtReleaseRuleFromPrefix.Text25 myCommand.Parameters("@New_ReleasingRuleSuffix").Value = txtReleaseRuleFromSuffix.Text26 myCommand.Parameters("@New_PlantID").Value = txtEndingPlantID.Text27 myCommand.Parameters("@New_RuleSetID").Value = txtEndingRuleSetID.Text28 myCommand.Parameters("@Count").Value = 129 myCommand.Parameters("@IDField").Value = " "
30 myCommand.Parameters("@IDFieldOut").Value = 031
32 myCommand.ExecuteNonQuery()33
34 Dim IDField As String = myCommand.Parameters("@IDFieldOut").Value35
If i run this stored procedure in sql it does return my parameter. But when i run this code IDField comes back null. Any ideas

I have a sqlserver stored procedure with multiple output parameter like below. I am not sure how I can read the two output parameters at my VB.net code. I am trying to use ExecuteScalar from VB.net and it is throwing an exception.
Procedure:CREATE PROCEDURE dbo.spGetUser
@UserLoginId VARCHAR(80), 'E-mail of user
@Password VARCHAR(50), 'Password in hash
@UserId INT=NULL OUTPUT, 'system generated user id@UserType CHAR(2)=NULL OUTPUT 'type of the user
AS
BEGIN
..........
END
VB Code:
Inside my business layer class
===========================
TryWith objSQLCommand
.CommandType = CommandType.StoredProcedure
.CommandText = "spGetUser".Parameters.AddWithValue("@UserLoginId", UserLoginId)
.Parameters.AddWithValue("@Password", Password).Parameters.AddWithValue("@UserId", UserId)
.Parameters.AddWithValue("@UserType", UserType).Parameters("@UserId").Direction = ParameterDirection.Output
.Parameters("@UserType").Direction = ParameterDirection.Output
End With
bolReturn = mobjDataAccess.Execute(objSQLCommand)
If bolReturn Then GetDetail = True
End If
==========================
Inside my dataaccess layer class
===========================
Public Function Execute(ByVal objSQLCommand As SqlCommand) As Boolean
Execute = False
Dim intReturn As Integer ' 0 = Success, Otherwise Error
intReturn = 1
TryCall Connect()With objSQLCommand
.Connection = mobjConnection
.ExecuteScalar()
End WithCall Disconnect()
If intReturn = 0 Then
Execute = TrueEnd If
Catch ex As ExceptionCall Disconnect()
ex.Source = "Execute"
Execute = False
End Try
End Function

I have a stored procedure that inserts a new record, and returns the ID value for the newly inserted record. The procedure works fine, but I'm unable to get that return value in my code. Here's what I have:
IF OBJECT_ID ( 'dbo.dbEvent', 'P') IS NOT NULL
DROP PROCEDURE dbEvent
GO
CREATE PROCEDURE
@Name varchar(200)
,@Location varchar(200)
AS
INSERT INTO Event
(
NAME
, LOCATION
)
VALUES
(
NAME
, @LOCATION
)
SELECT SCOPE_IDENTITY()
And my code behind: public Int64 Insert(SqlConnection Conn)
{
try
{
using (SqlCommand Command = new SqlCommand("dbo.dbEvent", Conn))
{
Command.CommandType = CommandType.StoredProcedure;
Command.Parameters.Add("@ID", ID).Direction = ParameterDirection.Output;
Command.Parameters.Add("@NAME", SqlDbType.VarChar, 200).Value = PermitName;
Command.Parameters.Add("@LOCATION", SqlDbType.VarChar, 200).Value = Location;
if (Conn.State != ConnectionState.Open) Conn.Open();
Command.ExecuteNonQuery();
Int64 _requestId = Convert.ToInt64(Command.Parameters.Add("@ID", SqlDbType.BigInt).Value.ToString());
return _requestId;
}
I'm getting the error that I have "Too many arguments specified" in my Insert() method. When I test the procedure in Query Analyzer, it works fine and returns the correct value.
Any suggestions? Don't I need to declare that return value in my .NET code as an output parameter?

Hi
I should validate a USER and if the user is not a valid user it should
return a message to the front end application for this I have a procedure

FETCH NEXT from C1 INTO @Temp
While @fetch_status = 0
BEGIN
If @Temp <> @Userid
-- IF the USER is not a valid USER ...It should not execute
the Futher code(statement) it should exit the procedure
by returning the error statement.

I have a stored procedure (named Insert_SRegister) that calls another
stored procedure (named: Generate_Student_Code) and a value should be returned from the second to the first one.
The program goes like this:
The first stored procedure inserts info of students and every student should have his own id which is gentratead by the second stored
procedure.
The second sp which generates the id does its job well and the first sp which inserts the info does its job well too, the Problem occurs when the genrated ID is to retrurn from the second sp to the first. I do no not know why it refuses to be transmitted in a correct way it gives no error but the id inserted in the db is always zero and I am sure that the id is generated in correct way, the problem occurs only in the transmission;
The code of the first procedur is :
Create Procedure dbo.Insert_SRegister

Hi,
I am trying to cast the parameter returned from the stored procedure to an int32 type. But it is giving me an error message as " Input string is not in the correct format "
my code is
int valid = Int32.Parse(command.Parameters["@Valid"].Value.ToString());
the @Valid parameter is an output parameter and is declared as int in the stored procedure.... the command is a DbCommand object
does anyone have an idea why this error is happening.

Greetings all! I'm writing a small content management program for a website that I'm putting together. One of the critical aspects of this projects is that users want to be able to cut n' paste from Word in to a FreeTextBox control and save it to the database. Well, we've run in to some problems. These entries are running well over 4000 characters, and I'm going to have to use an ntext datatype in order to the field to accomodate the amount of text they want to post.
My input stored procedures work great and it's dumping it well in to the table. But the problem I'm having is with the output. Apparently, you can't pass the values to an output parameter or reference the field directly in a stored procedure. I've scoured the internet and purchased several books just to deal with this issue. Can someone point me in the right direction or offer some examples of getting ntext data out through a stored procedure? I'm in a real squeeze here.
TIA

SELECT @parmRET1
--The parameter @parmRET1 returns NULL instead of 1 .
The @procName returns value 1 correctly if I run it separately ( outside of the dynamic sql)

Hi
Being a rookie to stored procedures the following cry for help will be posted.
The stored procedure below is supposed to create a dynamic string as an output parameter
create procedure spGetFieldNameList
@TableName varchar(256),@String varchar(8000) output
As
select @String = @String + sc.name + ','
from syscolumns as sc(nolock) join sysobjects as so(nolock)
on sc.id = so.id
and so.name = @TableName
order by colid asc
Creating the stored procedure does not trigger an error.
Calling the stored procedure as: spGetFieldNameList 'OfferCondition'.
Causes the following message:
Server: Msg 201, Level 16, State 4, Procedure spGetFieldNameList, Line 0
Procedure 'spGetFieldNameList' expects parameter '@String', which was not supplied.
Calling it this way:
declare @String as varchar(8000)
set @String = ''

Hi,
the stored procedure returns only the first letter of the ouput parameter i.e 'e'. spvr_ErrorDescription='error while updating data'. Actually It must return 'error while updating data'. can anybody help
me to solve this issue.How to set the size of output parameter
in dataaccess layer.
Below is the actual code
public string UserCostCenter_Upd(string spvp_Offering,
string spvp_UserId,
string spvp_CostCenter,
DateTime spvp_StartDate,
DateTime spvp_ExpiryDate,
ref string spvr_ErrorDescription)
{
// The instance ds will hold the result set obtained from the DataRequest
DataSet ds = new DataSet();
RequestParameter[] parms = new RequestParameter[7];
parms[0] = new RequestParameter("@Return_Value", DbType.Int32, ParameterDirection.ReturnValue, null, true);
parms[1] = new RequestParameter("@p_Offering", DbType.AnsiString);
parms[1].Value = spvp_Offering;
parms[2] = new RequestParameter("@p_UserId", DbType.AnsiStringFixedLength);
if (spvp_UserId == null)
parms[2].Value = DBNull.Value;
else
parms[2].Value = spvp_UserId;
parms[3] = new RequestParameter("@p_CostCenter", DbType.AnsiString);
if (spvp_CostCenter == null)
parms[3].Value = DBNull.Value;
else
parms[3].Value = spvp_CostCenter;
parms[4] = new RequestParameter("@p_StartDate", DbType.DateTime);
if (spvp_StartDate == null)
parms[4].Value = DBNull.Value;
else
parms[4].Value = spvp_StartDate;
parms[5] = new RequestParameter("@p_ExpiryDate", DbType.DateTime);
if (spvp_ExpiryDate == null)
parms[5].Value = DBNull.Value;
else
parms[5].Value = spvp_ExpiryDate;
parms[6] = new RequestParameter("@r_ErrorDescription", DbType.String, ParameterDirection.InputOutput , null, true);
parms[6].Value = spvr_ErrorDescription;
// Create an instance of DataSQLClient
AirProducts.GlobalIT.Framework.DataAccess.DataSqlClient daSQL = new DataSqlClient(Constants.ApplicationName); ;
// typDSRef holds the ref. to the strongly typed dataset
DataSet typDSRef = (DataSet)ds;
DataSet resultDataSet = daSQL.ExecuteDataSet("[ap_UserCostCenter_Upd]", ref parms);
// Call DataHelper.MapResultSet function for mapping the result set obtained in ordinary DataSet to strongly typed DataSet
DataHelper helper = new DataHelper();
if (!helper.MapResultSet(ref typDSRef, resultDataSet))
ds = null; // Returns a null reference if the DataHelper.MapResultSet is failed.
//returnCode = (int)parms[0].Value;
spvr_ErrorDescription = (string)((parms[6].Value == DBNull.Value) ? null : parms[6].Value);
return spvr_ErrorDescription ;
}

Hi guys. I have a procedure with just one parameter. That's a output parameter. It's type is NVARCHAR
I think there's no problem with the procedure. Now I want to execute it. Can I declare that variable passed by parameter to the procedure ? Must I use the Execute command ?
thanks a lot.

How can I declare output parameter in stored procedure, written in C++/CLR?
In C# it is proc_name( out SqlInt32 value ).
In VB.NET it is proc_name( <Out()> ByRef value As SqlInt32 ).
And in C++ ?
Thanks a lot for support.

Hello,
I am struggling with this, having read many msdn articles and posts I am non the wiser. I have a sproc with an output parameter @regemail. I can call the sproc OK from my code as below, via a tableadapter. And the sproc works as desired from management studio express. I want to get the result returned in the OUTPUT parameter (NOT the Return Value) and place it in a variable. Can anyone advise how I can do this? J.
THE CODE I USE TO CALL THE SPROC
Dim tableAdapter As New DataSet1TableAdapters.RegistrationTableAdaptertableAdapter.SPVerifyUser(strRegGuid, String.Empty)
THE STORED PROCEDURECREATE Proc [prs_VerifyUser
@regid uniqueidentifier,@regemail nvarchar(250) OUTPUT
ASBEGIN
IF EXISTS(SELECT RegEmail from dbo.Registration WHERE RegID = @regid)
BEGIN
SELECT @regemail = RegEmail FROM Registration WHERE RegID = @regid
Return 1
END
Return 2
END

Hi all,i have a problem and couldnt find anything even close to it. please help me, here is the description of what i m trying to accomplish:I have a trigger that is generating a column value and calling a stored procedure after the value is generated. And this stored procedure is setting this generated value as an output parameter. But my problem is:my asp.net page is only sending an insert parameter to the table with the trigger, trigger is running some code depending on the insert parameter and calling this other stored procedure internally. So basically i m not calling this last stored procedure that sets the output parameter within my web form. How can i get the output parameter in my webform? Everthing is working now, whenever an insert hits the table trigger runs and generates this value and called stored procedure sets it as an output parameter. I can get the output parameter with no problem in query analyzer, so the logic has no problem but i have no idea how this generated output parameter can be passed in my webform since its not initiated there.any help will greately be appreciated, i m sure asp.net and sql server 2000 is powerful and flexible enough to accomplish this but how??-shane

I am having a problem getting the output parameter from a stored procedure that deletes a record. I use the EXACT same process for the insert and update procs and they work fine. For some reason, the delete proc is either not returning an output parameter, or the SqlDataSource (dsCompany) is not able to get the information in the dsCompany_Deleted method. I simply want the proc to return an output value so that when I eventually get around to checking if the record can be deleted due to foreign key restraints, I can deliver the appropriate message to the user.I have highlighted the line that is giving the problem. I also highlighted a default value in the parameter, that when removed causes the app to crash because it is getting a null value back. Thanks in advance to anyone who can help!STORED PROC (eventually I will add foreign key restraints)

@iOutput int OUTPUT

Hello,I am currently trying to assign some string to a TEXT output parameterof a stored procedure.The basic structure of the stored procedure looks like this:-- 8< --CREATE PROCEDURE owner.StoredProc(@blob_data image,@clob_data text OUTPUT)ASINSERT INTO Table (blob_data, clob_data) VALUES (@blob_data, @clob_data);GO-- 8< --My previous attempts include using the convert function to convert astring into a TEXT data type:SET @clob_data = CONVERT(text, 'This is a test');Unfortunately, this leads to the following error: "Error 409: Theassignment operator operation cannot take a text data type as an argument."Is there any alternative available to make an assignment to a TEXToutput parameter?Regards,Thilo
