Scope Identity in SQL Server

Background

SCOPE_IDENTITY gets the last identity value inserted into a column that is a  defined identity in the same scope.

Scope may be a Stored Procedure, trigger, function or a batch statement.

The SCOPE_IDENTITY() function will return the most recent IDENTITY value inserted in the same scope (Stored Procedure, trigger, function or batch statement).

Note: It will return the NULL value if the function is invoked before any insert statements into an identity column in the scope.

Syntax

SCOPE_IDENTITY()

Return the type of the preceding function as a sql_variant.
