我正在尝试加入来自两个不同表格的列。
TBWORKFLOWPROCESS
,列名称为processname
TBLSTAPP
,列名称为isforreconsideration
,isforamendment
我的查询是:
select
pro.processname, app.isforreconsideration, app.isforamendment
from
TBWORKFLOWPROCESS pro
left join
TBLSTAPP app on app.applicationtype = pro.workflowid
where
sequenceno >= 10 and pro.workflowid = 1
group by
pro.processname, app.isforreconsideration, app.isforamendment
输出:
processname isforreconsideration isforamendment
------------------------------------------------------------------------
booked
booked,doc pending
cancelled
rejected
输出正确但我想要的是这个。
processname
---------------
booked
booked,doc pending
cancelled
rejected
isforreconsideration
isforamendment
任何人都可以帮我吗?谢谢你们。
答案 0 :(得分:0)
鉴于您提出的问题需要解释很多,并且基于我能理解的内容和许多假设,我认为您希望将相同条件下的两个属性(isforreconsideration和isforamendment)的值合并。在processname的属性下显示它们。
因此,在这里,我假设您需要一列下的所有数据。
在下面的代码中,我基本上只使用UNION
关键字添加了两行,因此将其重命名为另一列的不良编码。
select
pro.processname
from
TBWORKFLOWPROCESS pro
LEFT JOIN TBLSTAPP app on app.applicationtype = pro.workflowid
where
pro.sequenceno >=10
and pro.workflowid = 1
union
select
app.isforreconsideration as 'processname'
from
TBWORKFLOWPROCESS pro
LEFT JOIN TBLSTAPP app on app.applicationtype = pro.workflowid
where
sequenceno >=10
and pro.workflowid = 1
union
select app.isforamendment as 'processname'
from
TBWORKFLOWPROCESS pro
LEFT JOIN TBLSTAPP app on app.applicationtype = pro.workflowid
where
sequenceno >=10
and pro.workflowid = 1
P.S。 :我非常确定这段代码不是很正确,我可能已经触及了太多的神经,但是如果你能给出数据类型,每列都有,你想要的是哪种数据的例子输出,许多其他人将能够提供帮助。
