That did not take long... about 13 minutes to reload the tables from an *.mdb
file, and a second or two for each of the 'alter table foo add foreign
key...' lines. I tried to drop a 'referencing' table, and the database would
not let me, said that something depended on it ;o)
Is there some way to name the foreign key so that it can be dropped later, or
is there a way to drop the foreign key using information already in the
database?
John.
