    Description

      DELIMITER $$
      		 
      CREATE OR REPLACE PROCEDURE p1(a INT)
      		 
      BEGIN
      		 
        DECLARE res INT DEFAULT 0;
      		 
        IF (a < 0) THEN
      		 
          SET res=x;
      		 
        END IF;
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;

      Now if I call the procedure as follows:

      CALL p1(0);

      it still returns no errors.

      It only returns an error if the condition in IF evaluates to true:

      call p1(-1);


      ERROR 1054 (42S22): Unknown column 'x' in 'field list'

      This behavior makes it very difficult to design stored procedures.
      The error should happen during CREATE PROCEDURE time.

      In this context, x can only be a variable. It cannot be a column because no tables are involved.
