Return an unique identifier to an ASP.NET page to send it as a parameter into another stor

Hi !

I have a problem with the unique identifier and don't know how to solve it.

I have a stored procedure, called from my ASP.NET page, which inserts a new record into a table. I need to get the Id of the row just inserted in order to use it as a parameter of another stored procedure which inserts a new row with this value and other values.

I tried withSCOPE_IDENTITYbut i don't know how to ask for this value to the first stored procedure and stored it into an ASP variable.

Dim

cmdAsNew SqlCommand

cmd.CommandText ="Insertar_Contacto"

cmd.CommandType = CommandType.StoredProcedure

cmd.Connection = connect

Thanks!!

Create a parameter of type OUTPUT in your stored proc, assign the value of SCOPE_IDENTITY() to it after your insert, create the same parameter on your application layer, set its direction to OUTPU and retrieve the value. Search my posts here for some sample code as I posted some code for someone, in the last few days.|||

Have a look at

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO

CREATE PROCEDURE dbo.usp_Test_Insert
(
@.IsAdmin bit,
@.JobTitle nvarchar (50),
@.Name nvarchar (50),
@.DateCreated datetime,
@.RETURN INT OUTPUT,
@.IDENTITY INT OUTPUT
) AS
-- Purpose:
-- Insert record into Test table
-- Parameters:
-- IsAdmin -
-- JobTitle -
-- Name -
-- DateCreated -
-- RETURN - Zero or Error Code
-- IDENTITY - Identity of inserted row
-- History:
-- 11Jan2006 ACERXP\Administrator Original coding
SET NOCOUNT ON
INSERT INTO Test( IsAdmin, JobTitle, Name, DateCreated)
VALUES (
@.IsAdmin,
@.JobTitle,
@.Name,
@.DateCreated)
SELECT @.RETURN = @.@.error, @.IDENTITY = SCOPE_IDENTITY()
RETURN
----- this is the end ------
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
