PostgreSQL 8.3 on Windows. I have the table below which has a before
insert trigger. The CREATE TRIGGER statement and the trigger function
are also shown below. When I insert a row into this table using pgAdmin
III and the INSERT statement
insert into note.category (category_id, category)
values(689, 'Ztest');
the before insert trigger function is not called. The notice is not
displayed and no value is assigned to the version or uc_category columns
and the insert fails with a violation of the not null constraint on the
version field? I have created a simple two column test table with a
before insert trigger and it works perfectly. I am new to PostgreSQL so
I suspect I am missing something simple but I cannot figure out what.
Why is the trigger function never called?
Thanks,
Bill
