Обсуждение: droping unique constraint
Hi, can anybody help me with dropping unique constrint on attribute. I was looking for it in pg_attributebut I think this is done in some other way. How can I change it without recreating whole table. tia ps. list archives are unfortunately unusable... Marcin Mazurek -- Kierownik Działu Systemowego MULTINET SA o/Poznan http://www.multinet.pl/
When the unique constraint was added, it should have made a unique index on that column. Removing that index should remove the unique constraint (you may wish to make a non-unique index if you have queries that were using the index) Stephan Szabo sszabo@bigpanda.com On Tue, 24 Oct 2000, Marcin Mazurek wrote: > Hi, > can anybody help me with dropping unique constrint on attribute.
