I use this PROCEDURE to add new user.
I like to add GRANT statment to this PROCEDURE. (GRANT SELECT,
UPDATE ON TBLCUST TO USER TBLCUST.CID;)
How can I do? I am using firebird 1.5.3

/* ------------------------------------------------------------ */
CREATE PROCEDURE ADD_NEW_USER (
CID CHAR (8) CHARACTER SET WIN1251,
CNAME CHAR (30) CHARACTER SET WIN1251,
CPHONE CHAR (10) CHARACTER SET WIN1251,
CEMAIL CHAR (30) CHARACTER SET WIN1251,
CPSW CHAR (8) CHARACTER SET WIN1251)
AS

BEGIN
BEGIN
INSERT INTO TBLCUST (CID, CNAME,CPHONE,CEMAIL,CPSW) VALUES
(:CID, :CNAME,:CPHONE,:CEMAIL,:CPSW);
END
SUSPEND;
END
