DELETE Procedure. How To Return A Value?

Dec 3, 2006

Hello,

I created a DELETE Stored Procedure in SQL 2005.
When calling this procedure from my server code (VB.NET in my case) I
need to know if the record was deleted or not.

How should I do this?

Should I make the procedure to return True or False? If yes, how can I
do this?

My Stored Procedure is as follows (I think it is ok):

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[Content_DeleteContent]

  -- Define the procedure parameters
  @ContentName NVARCHAR(100),
  @ContentCulture NVARCHAR(5)

AS

-- Prevent extra result sets from interfering with SELECT statements.
SET NOCOUNT ON;

-- Declare and define ContentId
DECLARE @ContentId UNIQUEIDENTIFIER;
SELECT @ContentId = ContentId FROM dbo.Content WHERE ContentName =
@ContentName

-- Check if ContentId is Not Null
IF @ContentId IS NOT NULL
  BEGIN

    -- Check if ContentId is Null
    IF @ContentCulture IS NULL
                        BEGIN

                                -- Delete all localized contents from dbo.ContentLocalized
                                DELETE
                                FROM dbo.ContentLocalized
                                WHERE ContentId = @ContentId

                                -- Delete content from dbo.Content
                                DELETE
                                FROM dbo.Content
                                WHERE ContentName = @ContentName;

                        END
                ELSE

                        -- Delete localized content from dbo.ContentLocalized
                        DELETE
                        FROM dbo.ContentLocalized
                        WHERE (ContentID = @ContentID   AND ContentCulture = @ContentCulture)

  END

GO
Thanks,
Miguel

Return Error Code (return Value) From A Stored Procedure Using A Sql Task

Feb 12, 2008


I have a package that I have been attempting to return a error code after the stored procedure executes, otherwise the package works great.

I call the stored procedure from a Execute SQL Task (execute Marketing_extract_history_load_test ?, ? OUTPUT)
The sql task rowset is set to NONE. It is a OLEB connection.

I have two parameters mapped:

tablename input varchar 0 (this variable is set earlier in a foreach loop) ADO.
returnvalue output long 1

I set the breakpoint and see the values change, but I have a OnFailure conditon set if it returns a failure. The failure is ignored and the package completes. No quite what I wanted.

The first part of the sp is below and I set the value @i and return.


CREATE procedure [dbo].[Marketing_extract_history_load_TEST]

@table_name varchar(200),

@i int output

as

Why is it not capturing and setting the error and execute my OnFailure code? I have tried setting one of my parameter mappings to returnvalue with no success.

Using Delete With Sp_executesql And Getting Return Value

May 19, 2008


The basic syntax for the sp_executesql with a return value is:




Code Snippet
DECLARE @count int
DECLARE @ParmStr nvarchar(256)
set @count=0
set @ParmStr = N' @lvl tinyint, @cnt int OUTPUT'
execute sp_executesql
N'select @cnt=count(*) from pubs.dbo.employee where job_lvl = @lvl',
@ParmStr, @lvl = 35, @cnt=@count OUTPUT
print 'count: ' + cast(@count as nvarchar(4))




This returns a value of 3.

I need to change this to return the numbers of rows that were deleted, such as:




Code Snippet
DECLARE @count int
DECLARE @ParmStr nvarchar(256)
set @count=0
set @ParmStr = N' @lvl tinyint'
execute sp_executesql
N'delete from pubs.dbo.employee where job_lvl = @lvl',
@ParmStr, @lvl = 35
-- Need count
print 'count: ' + cast(@count as nvarchar(4))




Any ideas on how to modify this so that I can report on number of rows deleted?

Transact SQL :: Return Set Of Values From SELECT As One Of Return Values From Stored Procedure

Aug 19, 2015

I have a stored procedure that selects the unique Name of an item from one table. 

SELECT DISTINCT ChainName from Chains

For each ChainName, there exists 0 or more StoreNames in the Stores. I want to return the result of this select as the second field in each row of the result set.

SELECT DISTINCT StoreName FROM Stores WHERE Stores.ChainName = ChainName

Each row of the result set returned by the stored procedure would contain:

ChainName, Array of StoreNames (or comma separated strings or whatever)

How can I code a stored procedure to do this?

Using The Return Value From A Stored Procedure In VB

Nov 20, 2007

 Hi guys I know this is a really common question, and I have read loads of replies on it but everything I try does not work.  I have written a small stored procedure in SQL server to upload images to a table and return the new ID using scope_identity.  I have tested it and it works fine.  here it is:*******    @siteID numeric(18,0),    @imgNum numeric(18,0),    @title NVarchar(50),    @MIMEtype nchar(10),    @imageData varbinary(max)ASBEGINSET NOCOUNT ONdeclare @imageID intINSERT INTO [site_images] ([img_siteID], [img_num], [img_title], [img_MIME], [Img_Data]) VALUES (@siteID, @imgNum, @Title, @MIMEType, @ImageData) SET @imageID = SCOPE_IDENTITY()RETURN @imageIDSET NOCOUNT OFF************If I run this in management studio express it runs fine and returns the ID under 'return value'. The problem I have is trying to actually call that return value in VB.  If I try using these lines:Dim returnParam As SqlParameterreturnParam = New SqlParameter("@imageID", SqlDbType.UniqueIdentifier)returnParam.Direction = ParameterDirection.OutputcmdTest.Parameters.Add(returnParam)withcnBKTest.Open()cmdTest.ExecuteNonQuery() imageIDparam = returnParam.value.toStringcnBKTest.Close()  I get the error "procedure has too many arguments specified"And if I try to access the return value like this: imageIDparam = cmdTest.Parameters("@return_value").ValueI get the error "@return_value is not contained by this sqlparametercollection"  What am I doing wrong?  Any help would be greatly appreciated. Robsa

Getting A Return Value From A Stored Procedure

Nov 25, 2005

Hi all,Is there anyway to get a returned value from a called Stored Procedure from within a piece of SQL? For example, I have the following code...DECLARE @testval AS INTSET @testval = EXEC u_checknew_dwi_limits '163'IF (@testval = 0)BEGIN     PRINT '0 Returned'ENDELSEBEGIN     PRINT '1 Returned'END...which
as you can see calls a SP called 'u_checknew_dwi_limits'. This SP
(u_checknew_dwi_limits) actually returns a value (1 or 0), so I want to
assign that value to the '@testval' variable (as you can see in my
code) - but Query Analyser is throwing an error at me. Is this the
correct way to do this?ThanksTryst

How To Get The Return Value Of A Stored Procedure

Apr 28, 2006

I have a Stored procedure (sql 2000), that inserts data into a table. Then, I add this, at the end: Return Scope_Identity()
I have the parameters for the sProc defined and added to the Command, but I'm having a really lousy time trying to figure out how to get the return value of the Stored PRocedure. BTW - I'm using OleDB instead of SQL due to using a UDL for the connection string.
I have intReturn defined as an integer
I've tried :Dim retValParam As OleDbParameter = cmd.Parameters.Add("@RETURN_VALUE", OleDbType.Integer)retValParam.Direction = ParameterDirection.ReturnValueintReturn=cmd.Parameters("@RETURN_VALUE").Value
whenever I add this section - I get an error that there are too many arguments for the sProc.
I've tried:intreturn=cmd.ExecuteNonquery - tried adding a DataReader - using ExecuteScalar - I've tried so many things and gotten so many errors - I've forgotten which formations go with which errors.
What is the best way to do this in the code part (VB.Net)?
Thanks ahead of time

Dear all,

I have a store procedure called ValidateUser which retrtive an authneticated ID from a database.
This procedure is defined as follow :




Code Snippet
ALTER PROCEDURE [dbo].[ValidateUser]
-- Add the parameters for the stored procedure here
@LoginId int = 0 OUTPUT,
@UserName varchar(50),
@pw varchar(60),
@LineId varchar(16)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;

-- return the User id as validted
SELECT @loginID = Id
FROM [NomosConfig].[dbo].Users
WHERE [UserName] = @UserName
AND [PassWord] = @pw
AND [LineId] = @LineId
-- if no record returns, the request user is not allowed
if @@ROWCOUNT < 1
SELECT @loginID = 0

END




Runing this procesdure alone work well and return correct LoginId


What I would like to do is retrieve that return LoginID inside an other procedure. For that I am doinmg as follow :




Code Snippet
DECLARE @AuthenticatedUserId int;



-- verify that user is authorized to access to PSU login
EXECUTE @AuthenticatedUserId= [ValidateUser]
@UserName ='cal'
,@pw ='cal'
,@LineId='PR495250'
SELECT @AuthenticatedUserId




What is strange is that the @AuthenticatedUserId is always retunring 0 ..
Did I write something wrong ?

I am a newbie to SSIS and need some help. I need to get the return value from a stored procedure into a SSIS variable. I'm assuming I would use an OLE DB Command but I havn't a clue on how to capture the return value. Can someone get me started on how I can do this?

Note, the return value is actually an identity of the inserted value. I need this value in my data flow for further processing.

Thanks is advance!

Help With Delete Procedure?

Mar 18, 2008

Hi, I am kinda stuck on a delete stored procedure in my project and I was wondering if you could give me a hand.

My table is like this: Image <----FKconstraint ----- ImageNote --------FKconstraint------>Note.

What I want to do is delete all the notes linkeds to and Image through ImageNote when I am calling the storedprocedure DeleteImage:

So far I did something like this:


DELETE FROM [ImageNote] WHERE [Image Id]=@Id
DELETE FROM [Note] WHERE Id IN (SELECT [Note Id] FROM [ImageNote] WHERE [Image Id]=@Id)

DELETE FROM [Image]
WHERE (Id = @Id)
RETURN


Obvisouly the second DELETE statement won't work as ""SELECT [Note Id] FROM [ImageNote] WHERE [Image Id]=@Id"" won't return a thing at that time. However I have to delete ImageNote first due to the constraint.

A friend told me I should try a trigger, but perhaps there would be something easier to do with some kind of array?

Return Single Value From Stored Procedure

Jul 10, 2006

   I am have stored procedure that accepts one parameter and returns a single value
The sp works fine.
My question is how do I set the c# webpage to return the single value.
I need a specific example of how to code.
this is how the code should work.
A blank form is loaded, when the user clicks submit I need the code to pull the Login name from the text box and check to see if it exist. I have the sp working the way I need it to. But I can figure how to pull the single value into a variable in the code behind.
I am using dataset elsewhere on the site, so I created a ds the calls the sp. Can it work this way?
thanks,

cmd.Parameters["@LastModifiedBy"].Precision = 9;
cmd.Parameters["@LastModifiedBy"].Scale = 0;
cmd.Parameters["@LastModifiedBy"].Value = staffid;

SqlParameter sp = new SqlParameter("@OLDManagerReturn", SqlDbType.Int);
sp.Direction = ParameterDirection.Output;
cmd.Parameters.Add(sp);

lbl_ERROR.Text = Convert.ToString(sp);

conn.Open();
SqlTransaction trans = conn.BeginTransaction();
cmd.Transaction = trans;
cmd.ExecuteNonQuery();
conn.Close();
 My parameter sp is coming back null for some reason. Am I not setting the parameter correctly? I set a break point and it says the value is null.
 Here is the parts of my stored proc returning the value...
DECLARE @OLDManagerReturn numeric(9)
SELECT @OLDManagerReturn =  ManagerProfileID FROM tblBMS_Staff_rel_Staff WHERE StaffProfileID = @OldStaffProfileID AND Active=1 AND BudgetYear = @BudgetYear
RETURN @OLDManagerReturn

Dataset Stored Procedure Return Value

Mar 24, 2008

I'm not sure if anybody else is having a problem with the Return Value of Stored Procedures where you get the "Specified cast not valid" error, but I think I found a "bug" in VS2005 that prevents you from having a return value other than Int64 datatype. I tried to look for the solution for myself on the forums but unfortunately I just couldn't find it. Hopefully, this will help out anyone who had come across the same problem.
Basically, I have a stored procedure that I wanted to call as an Update for my ObjectDataSource that returns a Money value. Everytime I do this, I keep getting that error saying "Specified cast not valid" even when I try to change the @RETURN_VALUE data type to Currency or Money. After a long session of eye gouging moments, I decided to look at the code for my dataset. There, I noticed that the ScalarCallRetval for my StoredProcedure query was still set to System.Int64. I changed it to System.Object and, like a miracle, everything works like its suppose to.
Ex. protected void SomeObjectDataSource_Updated(object sender, ObjectDataSourceStatusEventArgs e)
{GrandTotalLabel.Text = ((decimal)e.ReturnValue).ToString("C");
}
