basic trigger ?

Hi
I want to have a trigger than when record is inserting into table A, the
trigger inserts a record into table B
I want the identity value from Table A to be one of the values inserted into
table B.
How do I get the indentity value from tableA in my trigger so that I can
insert into table b

CREATE TRIGGER A_tri ON A FOR INSERT AS
INSERT B (some_col, some_other_col, ...)
SELECT i.identity_col, i.other_col, ...
FROM inserted i
JOIN ...
inserted is a virttual table holds the inserted rows, so you find the
identity value right there.
Be aware of that a trigger fires once per *statement*.

You might want to consider using 'After Insert' instead of 'For
Insert'. This way you know that the record has been successfully inserted
into Table A, Before you insert into Table B.

For Insert triggers are classified as After Insert triggers, and only fire
after the row has been successfully inserted. Instead Of triggers fire in
place of the triggering action. If you want to perform an insert, then the
body of the Instead Of Insert trigger must issue an insert into the
underlying table.
