按条件查询

SQL code

select JO026,* FROM     [dbo].[APSJOB]where    JO015 IN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu')

我想实现：
JO026 = '0'加JO015 IN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu')条件限定
JO026 = '1'不加JO015 IN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu')条件限定

开始我想像下边这样写，显然思路和语法不对

SQL code

select *     FROM         [dbo].[APSJOB]whereJO015 IN CASE WHEN JO026 = '0' THEN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu')ELSE(SELECT DISTINCT RE002 FROM APSRES )END

[解决办法]

SQL code

select     case when JO015 IN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu') then '0'else '1' end as JO026,* from [dbo].[APSJOB]
[解决办法]
SQL code
select JO026,* FROM     [dbo].[APSJOB]where    (isnull(JO026,'0') = '0' and JO015 IN (SELECT RE002 FROM APSRES WHERE RE001 = 'liyu'))    or JO026='1'
