1：创建触发器，A表新增记录时B表也相应添加一条记录

CREATE TRIGGER task_insert
ON [A]
FOR INSERT
AS
insert into B(OrgAddr,DestAddr,SM_Content,SendTime,SubTime,ServiceID) 
select OrgAddr,DestAddr,SM_Content,SendTime,SubTime,ServiceID from Inserted 
go

?

2：左连接

select a.mobile,b.name
from tbl_senduser a left join tbl_employee b
on( b.mobile=a.mobile) where a.sjb_id=8

?

?

3：时间模糊查找

select * from tbl_gz where convert(varchar,edittime,120)   like '%2010%' 

?
