Hello everyone! Heres my question: I am using JDBC to connect to Postgres, and create a query. The ResultSet returned by the query contains MetaData about the table. I am using this table information to build a map of the table. I need to know how to retrieve an table, with NO rows, or alternativly, just 1 single row (even if more rows exist in the table). ie: SELECT * TOP 1 FROM TABLE //This does the trick in MS Access SELECT * FROM TABLE WHERE ROWNUM <= 1 //This works in Oracle? I need to know how to do this in STANDARD SQL. I would actually prefer getting NO rows from my query. I remember seeing something like: SELECT * FROM TABLE WHERE FALSE //This was someones proprietary QL to provide en empty table (what I would like) Anyone have any ideas? Also, I need to know how to do this *WITHOUT* any information about the coulmns in the table. No names, no keys, nothing. yikes. PS. Please copy directly to my email, because I am not subscribed to the majordomo. Thanks! Larry Wolcott bigdog@pitnet.net
