CREATE PROCEDURE innerproc(OUT param1 INT)
BEGIN
insert into sometable;
SELECT LAST_INSERT_ID() into param1 ;
END
-----------------------------------
CREATE PROCEDURE outerproc()
BEGIN
CALL innerproc(@a);
// @a gives you the result of innerproc
SELECT @a INTO variableinouterproc FROM dual;
END
OUT parameters should help you in getting the values back to the calling procedure. Based on that the solution must be something like this.
