Dear Sir, I was wondering on mailing list for last 3 days and I didn't get proper response, I am really in problem. I am getting problem to use Mysql Stored procedures with Freeradius. After exploring web It came to know that, (this text I got from mysql.com forum:) the result's of SP execution are sent as result sets over the protocol. Once you call a SP you get at least 1 return code and could get many result sets. The execution of a stored procedure is very similar to execution of a multi-query. MySQL 5.0 supports the execution of multiple statements specified in a single query string. To use this capability with a given connection, you must specify the CLIENT_MULTI_STATEMENTS option in the flags parameter to mysql_real_connect() when opening the connection. You can also set this for an existing connection by calling mysql_set_server_option(MYSQL_OPTION_MULTI_STATEMENTS_ON). By default, mysql_query() and mysql_real_query() return only the first query status and the subsequent queries status can be processed using mysql_more_results() and mysql_next_result(). /* Connect to server with option CLIENT_MULTI_STATEMENTS */ mysql_real_connect(..., CLIENT_MULTI_STATEMENTS); /* Now execute multiple queries */ mysql_query(mysql,"DROP TABLE IF EXISTS test_table;\ CREATE TABLE test_table(id INT);\ INSERT INTO test_table VALUES(10);\ UPDATE test_table SET id=20 WHERE id=10;\ SELECT * FROM test_table;\ DROP TABLE test_table"); Means I need to use CLIENT_MULTI_STATEMENTS in mysql_real_connect(), so, for now, I just need this little guidance that which file should I edit to get SP working with Freeradius. I hope I'll get response this time thanking you in advance Best Regards
