No, I am not trying to delete with a select statement. That was just there
to show my tables, fields, etc.
So if I understand what you are saying I can not do a delete statement with
a join in it. I would have to query each individual row for the ID that need
to be deleted, delete the row in the first table, then delete the row in the
second table, third table, etc. Then loop for the next intance. Theres got
to be a better way. Also, after this is done should I run some sort compact
or defrag on the database that restore wasted space?
Thanks,
Shaun
