Hi mohan, can you please try the below code. Here I have used customer and accounts table for example. If there is an error signal, customer table will be printed, else account table will be printed.

DELIMITER $$
CREATE DEFINER=dbadmin@% PROCEDURE transactionCode()
BEGIN
    DECLARE _rollback BOOL DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET _rollback = 1;
        
    START TRANSACTION;
        SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = "This above executed SQL statements will be rollbacked";
    IF _rollback 
    THEN
        ROLLBACK;
        SELECT * from Customer;
    ELSE
        COMMIT;
        SELECT * from accounts;
    END IF;
END$$
DELIMITER ;
