MySQL Select into variable
I want to further use in the procedure the values I get from a select into execution but can't figure out how to do it. As a test I wrote the following but cannot use the v_1, v_2 or v_3 variables for further logic as they don't take the values 1,2 & 3 as i expected... DROP PROCEDURE IF EXISTS MPT_testing; DELIMITER // CREATE PROCEDURE MPT_testing() READS SQL DATA BEGIN DECLARE v_1 INT; DECLARE v_2 INT; DECLARE v_3 INT; SET @sql=CONCAT('SELECT 1,2 into v_1, v_2'); PREPARE s1 FROM @sql; EXECUTE s1; DEALLOCATE PREPARE s1; SET v_3 = v_1 + v_2; SELECT v_3; END // DELIMITER ; Can somebody help here
