SCOPE_IDENTITY()

Trying to insert record in Parent table and return value of that rows IDENTITY, to pass back to app for use inserting child rows into other table. Looks clean against tutorial samples(http://aspnet.4guysfromrolla.com/demos/printPage.aspx?path=/articles/050207-1.aspx). Works with Insert until *** lines are added - HELP?

ERROR:

Msg 201, Level 16, State 4, Procedure qc_submitInsertQCparentReturningID_2, Line 0

Procedure or function 'qc_submitInsertQCparentReturningID_2' expects parameter '@.newQCparent_ID', which was not supplied.

Based on this Procedure:

ALTER PROCEDURE qc_submitInsertQCparentReturningID_2

(@.newQCparent_ID INT OUTPUT) ***

AS

-- Insert New QCparent RETURNING qcParentID

INSERT INTO app.dbo.a1_qcParent

([rowCreatedBy]

,[rowNotes]

,[rowLastAction]

,[rowLastActionBy]

,[rowLastActionNote])

-- Using Parameter Variables

VALUES('Anonymous Submit'

,'By qc_submitInsertQCparentReturningID'

,'Insert'

,'Guest'

,'show donald')

-- Read the qcParient_ID back for Items2fix Insert

SET @.newQCparent_ID = SCOPE_IDENTITY() ***

- Try New SPROC

EXEC qc_submitInsertQCparentReturningID_2

Thanks, unfortunately neither worked...

snippet 1 Error (EXEC qc_submitInsertQCparentReturningID_2 @.newQCparent_ID=@.newQCparent_ID):

Sorry, I got it wrong; Leave your original procedure code as it was. Change your call of the stored procedure from

Code Snippet

EXEC qc_submitInsertQCparentReturningID_2

to

Code Snippet

declare @.outputParm integer

EXEC qc_submitInsertQCparentReturningID_2 @.newQCparent_ID=@.outputParm output

and if you wish to see the results something like:

Code Snippet

declare @.outputParm integer

EXEC qc_submitInsertQCparentReturningID_2 @.newQCparent_ID=@.outputParm output

select @.outputParm as [@.outputParm]

|||

Parameters are by default NULLable in SQL Server. But in case of OUTPUT parameters, you will have to always pass a value. So if you want to ignore the output value you can do:

exec qc_submitInsertQCparentReturningID_2 NULL;

If you need to retrieve the output value then do:

declare @.id int;

exec qc_submitInsertQCparentReturningID_2 @.id OUTPUT;

THat allowed it to run, insert was successful, but the following resulted in 9 as scope_Identity but 14 rows listed:

- Try New SPROC

declare @.id int;

exec qc_submitInsertQCparentReturningID_4 @.id OUTPUT;

go

Select SCOPE_IDENTITY()

go

Select * from a1_qcParent

a) I was expecting to see the same scope as the last inserted rows ID (14) ?

and

b) can I use the @.id to populate another procedure insert ?

|||Removed the GO between statements, but Scope_Identity remained 9 while rows increased|||

In the statement:

Code Snippet

declare @.id int;

exec qc_submitInsertQCparentReturningID_4 @.id OUTPUT;

go

Select SCOPE_IDENTITY()

go

Select * from a1_qcParent

The SCOPE_IDENTITY() function will not work as you are thinking -- because the IDENTITY column is assigned inside of the stored procedure and what happened there is NOT in the scope of the CALLING query. As I said above, you will need to do something like

Code Snippet

declare @.id int;

exec qc_submitInsertQCparentReturningID_4 @.id OUTPUT;

Select @.id

Select * from a1_qcParent

scope_identity question

I have a app that is inserting data into a SQL 2005 database and I would like to return the UniqueID of the inserted record.

I am using

Dim queryStringAsString ="INSERT INTO dbo.DATATABLE (FIELD) VALUES (@.FIELD);SELECT Scope_Identity()"

Dim sIDAsString = comSQL.ExecuteScalar()

This isn't working - it says the value returned is DBNull...

Any ideas on how to make this work?

You can convert the adhoc SQL to a stored proc and use a proper OUTPUT parameter and retrieve the ID. Also, is that your entire code? Where are you opening the connection? where is it define/initialized etc?

hi mate,

The syntax used for retriving identity value is worn...It will be as follows

SELECT @.@.SCOPE_IDENTITY

Otherwise you can use

SELECT @.@.Identity

Hope now i can see ur smile

Thanx

Vijay

Your use of scope_identity() is correct. Perhaps your insert is failing. Can you make sure that new row are actually being added to the table?

SELECT @.@.SCOPE_IDENTITY

This is incorrect. The correct way to use it is SCOPE_IDENTITY().
