Question

I have a table let us say TableA. I have created a trigger which is fired on Insertion, Update or Deletion of record in TableA and inserts record in another table let us say TableB. Now where am I finding difficulty is from some of the stored procedures of TableA I am returning scope_identity() of inserted record. That must be returned from TableA's record while I am getting it from TableB. Is there any way to solve this issue? I want scope_identity() from TableA only, NOT from TableB. Awaiting for your valuable response.

Thanks in advance..

SCOPE_IDENTITY() should work in that situation, it should be scoped to your stored proc and the insert to TableA, not the insert done in the trigger.

CREATE TABLE [dbo].[TableA](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [TestColumn] [nvarchar](50) NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[TableB](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [TestColumn] [nvarchar](50) NULL
) ON [PRIMARY]

CREATE TRIGGER [dbo].[TableA_AIDU]
   ON  [dbo].[TableA]
   AFTER INSERT,DELETE,UPDATE
AS 
BEGIN
    SET NOCOUNT ON;
    INSERT INTO TableB ( TestColumn )
    SELECT 'TableA Modified'
END

CREATE PROCEDURE [dbo].[sp_InsertToTableA]
    @ID INT OUTPUT  
AS
BEGIN
    SET NOCOUNT ON;
    INSERT TableA ( TestColumn )
    SELECT 'Insert from sp_InsertToTableA'
    SET @ID = SCOPE_IDENTITY()
END

The stored proc returns the ID from TableA, and the TableB insert is triggered as expected. Are you sure you’re not using @@IDENTITY instead of SCOPE_IDENTITY()?
