Then table names will not be treated as case sensitive, and you can write them in any lettercase in your queries. Two points to note, though: - Before setting the varable, rename all your tables to lowercase. Otherwise they won't be recognized properly when you set the variable. (The way it works is that if causes the server to lowercase the names of new tables when they are created.) - Although you will be able to refer to tables using any lettercase, *within a given query*, you must refer to the table consistently.

Besides, if you set it with a SET statement, the value would be lost the next time you start the server. Best to put it in an option file so that it's used each time the server starts up: [mysqld] lower_case_table_names=1 -- Paul DuBois, Senior Technical Writer Madison, Wisconsin, USA MySQL AB, www.mysql.com Are you MySQL certified? http://www.mysql.com/certification/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
