The QTC error arises when the entire query exceeds 64KBytes after
compilation. It's probably just coincidence that this is happening
after 30 joins in your case.
I really have to wonder about your table structure! Sounds like a sea
urchin... are you linking 30 (or fifty, or how many?) dependent tables
to 30 (or fifty) separate fields, or what?
I have a table registrants with many tables linked to it.
For instance there are tables marriage status, referred
by, and so on... This query I wanted for a report that
would print out all of the Info not just the codes that
were used in the registrant table to link to the other
fields.
