Using the @@IDENTITY
I am using MS SQL 2000, with vb.net. I have the following query that inserts some information into two different tables.
Table1 has a primary key that is used to relate to Table2. After the information has been inserted into the tables, I want to return the PropertyID (@@IDENTITY). This all works, if I don't include the second insert. But when I include the second insert as shown, the return value for @@IDENTITY is 0.
Thanks in advanced!

CREATE PROCEDURE [dbo].[Add_Residential_Property]

@UserID As int,
@CountryID As int,
@LandDimensions As int,
@SQFT As int,

AS

INSERT INTO Table1(CountryID,LandDimensions)
VALUES( @CountryID, @LandDimensions)

INSERT INTO Table2(PropertyID, LandDimensions, SQFT)VALUES(@@IDENTITY, @GarageCap, @TotalBeds)

RETURN @@IDENTITY
GO

Code:
CREATE PROCEDURE dbo.Add_Residential_Property

@UserID As int,
@CountryID As int,
@LandDimensions As int,
@SQFT As int

AS

declare @id int

set nocount on

INSERT INTO Table1(CountryID,LandDimensions)
VALUES( @CountryID, @LandDimensions)

set @id = @@identity

INSERT INTO Table2(PropertyID, LandDimensions, SQFT)VALUES(@id, @GarageCap, @TotalBeds)

select @id
GO


You shouldn't use return in this case as it is more intended for reporting a status back to the caller. You should also include some error handling.

Without the set nocount on option each update/insert/delete statement will return an empty result set to the client.
