Question

What the question title says. With a query such as SELECT @@IDENTITY AS ins_id, do I need to supply the table name or any other info to specify which table/database i’m talking about?

Answer 1

@@IDENTITY returns the most recent identity generated in the current session. In most cases you’ll probably want to use SCOPE_IDENTITY instead, which returns the most recent identity generated in the current scope.

For example, if you insert a row into table1, but that insert fires a trigger which inserts a row into table2, then @@IDENTITY will return the identity from table2 whereas SCOPE_IDENTITY will return the identity from table1.

INSERT INTO my_table (my_column) VALUES ('test')  -- return the identity of the row you just inserted into my_table -- regardless of any other inserts made by triggers etc SELECT SCOPE_IDENTITY() AS ins_id
