Thread: Metadata/ODBC query
Hi
I'm experimenting with PostgreSQL 8.3.0 on Windows connecting via ODBC. One curiosity so far is this:
If I use pgAdmin and run "SELECT catalog_name FROM Information_Schema.Schemata" I get data back as expected.
If I connect via ODBC and issue the same query I don't see any data. SQLFetch() simply returns SQL_NO_DATA_FOUND. Both ODBC test apps work fine when accessing the same server/database running queries such as "SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE table_type = 'BASE TABLE'"
I'm using the latest psqlODBC Windows installer from the web site. The driver is set to show system tables ...
Any clues?
Thanks.
Jerry.

What userid are you connecting as under ODBC? Has it got privileges to
any of the schemas? The information_schema views generally hide objects
that you have no privileges for ...

In fact, looking closer, it looks like the schemata view only shows you
schemas that you are the *owner* of (as is required by spec). So a
superuser would see everything but ordinary users might well not see
anything.
