In order to successfully change users a valid username and password parameters must be provided and that user must have sufficient permissions to access the desired database. If for any reason authorization fails, the current user authentication will remain. Using this command will always cause the current database connection to behave as if was a completely new database connection, regardless of if the operation was completed successfully. This reset includes performing a rollback on any active transactions, closing all temporary tables, and unlocking all locked tables. &reftitle.returnvalues; &return.success; &reftitle.examples; query("SELECT * FROM dual")) { $row = $result->fetch_row(); printf("Result: %s\n", $row[0]); $result->free(); } /* reset all and select a new database */ if (!$maxdb->change_user("DBADMIN", "SECRET", "DEMODB")) { printf("Database not running\n"); } else { printf("Database running\n"); } /* close connection */ $maxdb->close(); ?> ]]> ]]> &example.outputs.similar; &reftitle.seealso; maxdb_connect maxdb_select_db
