Question

Is is possible to get new values for Id (IDENTITY) before inserting data in a table ?

Is is possible to write something like that :

INSERT INTO Table1
SELECT *GET_NEW_IDENTITY*, Field1, Field2 FROM Table2

I need the values of Id because I want to insert data in Table1 and, just after, insert data in another table which has a foreign key linked to Table1 (with Id)

Answer 1

IDENT_CURRENT. Returns the last identity value generated for a specified table or view. The last identity value generated can be for any session and any scope.

SCOPE_IDENTITY. Returns the last identity value inserted into an identity column in the same scope. A scope is a module: a stored procedure, trigger, function, or batch.

OUTPUT. Returns information from, or expressions based on, each row affected by an INSERT, UPDATE, DELETE, or MERGE statement. […] The OUTPUT clause may be useful to retrieve the value of identity or computed columns after an INSERT or UPDATE operation.
