Commit And Rollback Problem

Hi,

I still haven't got a decent book on relational databases :-)

My stored procedure insert_wire inserts values into two tables (wire and
cablewire). The wire_ref (primary key) will be the same for both inserts.
However, if for any reason the first insert fails then I would like a
rollback system to take place. I have tried testing for an error (@@error
<> 0) after the 1st transaction but I just get a syntax error. Am I going
down the right lines here? Any tips appreciated.

Thanks, Mary.

CREATE procedure insert_wire(in wire_ref VARCHAR(22), in standard
VARCHAR(16), in a_color VARCHAR(16), in material VARCHAR(22),
in metres INTEGER, in amps FLOAT(3), in volts FLOAT(3), in ni SMALLINT, in
some_comment VARCHAR(32))
BEGIN
insert into cablewire
values(wire_ref, standard, a_color, material, metres, some_comment);
insert into wire
values(wire_ref, amps, volts, ni);
commit;
END!
