初用sysbase ,写了个简单存储过程在PB中调用怎么没执行呀?以下是代码:

CREATE PROCEDURE dbo.sp_model_prepare;1
/* [ (@param_name datatype [= default] [output] ), ... ] */
@end_date datetime
AS
BEGIN
truncate table tmp

update statistics tmp
insert into tmp select id_xh,id_xm,id_je,max(date_fix)
from main
where date_fix < dateadd(month,1,@end_date)
group by id_xh,id_xm,id_je

END

执行后什么反应也没有,tmp库没变化,跟没执行一样??
