Hi, guys, In the database theory each table is identified as "schema_name"."table_name". When I tried to look at how to get the table id inside the PostgreSQL, I saw that I needed to look at the pg_class table. SELECT oid FROM pg_class WHERE relname = "table_name"; However that query will give a non-unique table id (see the first sentence). So how do I get the table id based on the "schema_name.table_name"? There is a pg_namespace table - is this where the schema should come from? If yes - how? Looking at that table I don't see any unique fields... Or is this something that is hidden? In fact I'm trying to run following query: SELECT c.oid FROM pg_class c, pg_namespace nc WHERE nc.oid = c.relnamespace AND c.relname = ? AND nc.nspname = ?; from my ODBC based program, but it returns 0 rows on SQLFetch. I know PostgreSQL does not use '?' for query parameters but I thought that since its an ODBC everything should work. Nevertheless, all bindings were successful, but now rows are returned. Is this query correct? Thank you.
