SQL Output Clause SQL Server

SQL Server- Output clause

Byvivekjohari

Jan 22, 2012 #SQL Advance Concepts, #SQL Output Clause
Output Clause:- The SQL SERVER 2005 gives us an Output Clause which gives us the information about each row affected by the Insert, Update , Delete and Merge statement. It is more useful than @@scope_Identity and @@Identity column since these global variables gives us the information about the last inserted identity column value, but the Output clause gives us the last affected identity in case of Inserted, deleted, updated and merge statement. Output clause has the access to the Magic tables (Inserted and deleted) and we can capture the records of affected rows into the temporary tables too for latter use.

Create table Tbl_output (id int identity(1,1), fname nvarchar(100), lname nvarchar(100))

Example of Output clause in case of Insert command

Declare @outputtemp Table  (id int , fname nvarchar(100), lname nvarchar(100))

Insert into tbl_output(fname,lname)
Output inserted.id, inserted.fname, inserted.lname into @outputtemp
values(‘Vivek’, ‘Johari’)

Select * from @outputtemp

Example of Output clause in case of Update command
