>but i do not understand
>1. the output into clause
that OUTPUT INTO clause saves the data into a table (variable), so you can proceed working on the data after the insert.
in this case, it's not really needed, visibly

>2. the output clause
the OUTPUT clause, without INTO, will just do what a SELECT would do with the inserted records.

>3.why it shows a single record?
because there is only 1 record inserted (VALUES calsue ...)

SQL Server 2005 has new OUTPUT clause, which is quite useful. OUTPUT clause has accesses to inserted and deleted tables (virtual tables) just like triggers. OUTPUT clause can be used to return values to client clause. OUTPUT clause can be used with INSERT, UPDATE, or DELETE to identify the actual rows affected by these statements.

OUTPUT clause can generate table variable, a permanent table, or temporary table. Even though, @@Identity will still work in SQL Server 2005, however I find OUTPUT clause very easy and powerful to use. Let us understand OUTPUT clause using example.
