Un error en CREATE PROCEDURE que no encuentro la solución :

[alkortius]

CREATE PROCEDURE x.nombre (IN F CHAR,IN V CHAR, IN column1 CHAR(8),IN column2 CHAR(1))
BEGIN
.......
DELETE FROM tabla1 AS A WHERE A.id = id AND A.column1 = column1 AND
A.column2 = column2;
.......



Script line: 3 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AS A WHERE A.id = id AND A.column1 = column1 AND A.column2 = column2;
' at line 14

Gracias por tu atención.
