Answer 1

Use the below code. This is working fine. And follow the MySQL prepared statement https://dev.mysql.com/doc/refman/5.7/en/sql-syntax-prepared-statements.html

SET @max_id = (SELECT MAX(id) FROM `ids_tbl` );
SET @sql = CONCAT('ALTER TABLE `outgoing_tbl` AUTO_INCREMENT = ', @max_id);
PREPARE st FROM @sql;
EXECUTE st;
