Hello !
I would like to write a PL/PGSQL trigger that will store changes (Table
name / Column name / primary key id / OLD value / NEW value) in several
tables.
As I said, this trigger must be usable for every table (it assumes that
theses table will have only one primary key).
In order to that, I have to iterate fields into the NEW.*
How can I do that iteration ?
Many thanks in advance for any tips !
Regards,
