I'll admit straight away I'm a novice, but this one has me perplexed....
I have a table, T1, with a column (userid) that is an int4 generated from a
sequence.
I have a second table (T2) that I wish to use to hold audited values from
T1.
I have created a trigger function written in PL/PGSQL, set to be for each
row after update on T2, which is supposed to copy the OLD values into T2.
The snag is that when I try to update a row in T1 I get:
ERROR: record "old" has no field "userid"
This behaviour does not seem to be documented anywhere. Am I just being
dense?
TIA,
Steve S
