I know this won't work, tried it in various forms and failed all times. What is the simplest way to achieve the following result?
ALTER TABLE XYZ AUTO_INCREMENT = (select max(ID) from ABC);
This is great for automation projects. Thank you!
SELECT @max := (max(ID)+1) from ABC; -> This works! select ID from ABC where ID = (@max-1); -> This works! ALTER TABLE XYZ AUTO_INCREMENT = (@max+1); -> This fails :( Why?
Use a Prepared Statement:
SELECT @max := MAX(ID)+ 1 FROM ABC; PREPARE stmt FROM 'ALTER TABLE ABC AUTO_INCREMENT = ?'; EXECUTE stmt USING @max; DEALLOCATE PREPARE stmt;
