Thread: CREATE TABLE IF NOT EXIST
Hi Postgres Experts,
I'm trying to create tables (if they don't exist) through the ODBC driver. I've tried the following:
SELECT relname FROM pg_class WHERE relname = 'mytable';
This works from the psql command line program when logged into my database, but not when connected to my database over ODBC ( I get SQL_NO_DATA back from SQLFetch)
Any ideas? Are there other ways to find out if a table exists?
Many thanks,
Mike
IF NOT EXISTS(SELECT tablename FROM pg_catalog.pg_tables WHERE tablename = 'mytable')
....
IF NOT EXISTS(SELECT table_name FROM information_schema.tables where table_name = 'mytable')
Maybe the problem you are having is a permissions problem though. Are you using the same account in psql as you are in ODBC?
Hope that helps,
Regina
