Don't do that. It is going to drive you nuts. Usually people get mixed case table and column names when they export an Acess database or another database via ODBC to Oracle. The tool will quote all the table and column names and thus make them mixed case. Which means you have to type select "myColumnOne","myColumnTwo" from "myTable" where "myColumnOne"=5; Jim Received on Sat Jan 31 2004 - 17:54:57 CET
