Hello to all the SQL gurus...
I have this little table:
test1 ( id char(8) primary key, name char(20), create_date timestamp
);
Now, the create_date need to be updated
to date and time whenever id is being
inserted or updated.
Is there a way in SQL that I can do this
automatically?
I try the following command using 'trigger'
----
CREATE_TRIGGER test1_autodate AFTER INSERT OR UPDATE ON test1 FOR EACH ROW EXECUTE update("test1")
CREATE FUNCTION update(char *) RETURNS int4 AS 'UPDATE $1 set date="now"' LANGUAGE 'sql';
----
But realized 'char *' is not allow... Is there a
way to solve this?
Or Am I the right track in solving this problem?
Hope someone can help me... thanks.
Sei Heng
