方法一：



select distinct A.ID from  A where A.ID not in (select ID from B)


方法二：



select A.ID from A left join B on A.ID=B.ID where B.ID is null


方法三：



select * from  B  where (select count(1) as num from A where A.ID = B.ID) = 0


方法四：



SELECT * FROM b WHERE NOT EXISTS(SELECT 1 FROM a WHERE tel_no=b.tel_no)


 

方法五：



SQLServer两张表筛选相同数据和不同数据_javascript

--相同数据
select tel_no from a
intersect
select tel_no from b

--不同数据
select tel_no from b
except
select tel_no from a


SQLServer两张表筛选相同数据和不同数据_数据_02
