I realized I made my previous post look like it was a reply and not the
original question, so here I go again... =o)
Original message below
=========================================================================
Hello,
I have tables in a user administration database and need to link different
tables with FK's for integrity.
How do I do this?
for example:
I have two tables, one called applications, the other called
forum_moderators.
Applications Catches all form submissions.
Forum_Moderators hold the details of active/current moderators
I want to link these two tables by rsm_id in applications, and fk_rsm_id in
forum_mod's.
How would i do this in MySQL and or PHP?
Table Structure:
for those that need a clearer picture of my layout, I have supplied the SQL
statement to create the tables
#--------------------------------------------------------

# Table structure for table 'applications'
#
DROP TABLE IF EXISTS applications;
