A Perl script that needs to update a referring table with many new
entries before knowing the foreign keys for each new record. (I
described a similar situation in a recent post, Subject: Populating
large DB from Perl script.)
Also, Ron, the *owner* of a table is not a "regular user" as far as
that table is concern. That user has special privileges, including
that of dropping constraints. What I seek to do is no greater a
violation of the idea of enforcing relational integrity than is the
ability to drop constraints altogether.
BTW, I realize that I can just drop and reinstate constraints, but
from the point of view of writing a Perl script to do all this, it
would be much easier if I could just disable temporarily all the FK
constraints on a table.
