Re: CREATE TABLE IF NOT EXIST

["Obe, Regina" <robe(dot)dnd(at)cityofboston(dot)gov>]

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

Subject: [ODBC] 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
