How to Reset an MySQL AutoIncrement using a MAX value from another table?

Question

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_INCRE         


        

Answer 1

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;
