Answer / honey
SELECT @@IDENTITY
It returns the last IDENTITY value produced on a
connection, regardless of the table that produced the
value, and regardless of the scope of the statement that
produced the value.
@@IDENTITY will return the last identity value entered into
a table in your current session. While @@IDENTITY is
limited to the current session, it is not limited to the
current scope. If you have a trigger on a table that causes
an identity to be created in another table, you will get
the identity that was created last, even if it was the
trigger that created it.
SELECT SCOPE_IDENTITY()
It returns the last IDENTITY value produced on a connection
and by a statement in the same scope, regardless of the
table that produced the value.
SCOPE_IDENTITY(), like @@IDENTITY, will return the last
identity value created in the current session, but it will
also limit it to your current scope as well. In other
words, it will return the last identity value that you
explicitly created, rather than any identity that was
created by a trigger or a user defined function.
SELECT IDENT_CURRENT(‘tablename’)
It returns the last IDENTITY value produced in a table,
regardless of the connection that created the value, and
regardless of the scope of the statement that produced the
value.
IDENT_CURRENT is not limited by scope and session; it is
limited to a specified table. IDENT_CURRENT returns the
identity value generated for a specific table in any
session and any scope.
To avoid the potential problems associated with adding a
trigger later on, always use SCOPE_IDENTITY() to return the
identity of the recently added row in your T SQL Statement
or Stored Procedure.
