Обсуждение: How to rename a constraint/trigger??
Hi to all,
I have a database, where in the tables I have around 100 constrains (link to other tables) that don't have a name "<unnamed>" or they have a name like "$1" "$2". Now, I have a module which bases on the same structure, but I get some query errors from a "<unnamed>" constraint. I really don't know exaclty which the constrain generates the error, in that table I have 12 such constrains.
Does anyone have a script or it exist a command so that I can rename all the "<unnamed>"constrains in this database?
I'm using postgre 7.3.2.
Thankx,
Andy.

You'll be happy to know that in 7.4 we stopped using "<unnamed>". > Does anyone have a script or it exist a command so that I can rename all > the "<unnamed>"constrains in this database? You can't rename constraints, you have to drop and re-create them under a new name (do this in a transaction for data safety). However, this requires knowing what all those constraints do. I'd suggest doing a text pg_dump file of your schema only (no data) and looking in the constraints section at the end. -- Josh Berkus Aglio Database Solutions San Francisco
