Question

有人可以帮忙解决问题，我还要加入两个CTE＆＃39;

Msg 102，Level 15，State 1，Line 19 ＆＃39;（＆＃39;附近的语法错误。消息156，第15级，状态1，第26行关键字＆＃39; left＆＃39;附近的语法不正确。

查询：

   with Cte_LatestPatInfo as

    (select max(a.LogID) as LastPatRec, p.unitnum, p.PatNum, a.iplan from         rrscsql2.arhighdollar.dbo.tblarinfoHistory a
    inner join rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
    on a.patID=p.patID and a.LogID=p.LogID
    where a.Active = 1
    and a.ReasonCode is not null
    group by  p.unitnum, p.PatNum, a.iplan)

    select *,rc.Description from  rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
    inner join cte_LatestPatInfo li
    on p.PatNum=li.PatNum and p.UnitNum=li.UnitNum and p.LogID = li.LastPatRec
    inner join  rrscsql2.arhighdollar.dbo.tblarinfoHistory ah 
    on ah.LogID=p.LogID and ah.iplan = li.iplan and p.PatID=ah.PatID
    left join rrscsql2.ARHighDollar.dbo.tblReasonCodes rc 
    on ah.ReasonCode=rc.ReasonCode,

    cte_EOMDenials as
    (select d.* from rrscsql2.Denials.dbo.tblDenialMonthEnd d 
    Inner join rrscsql3.Facilities.dbo.vwFacilities f
    on d.UnitNum = f.UnitNum and f.Owner like '%LifePoint%'
    Inner join rrscsql2.Denials.dbo.tblDispositionDictionary t
    on d.disposition=t.disposition and DispositionType like'O%'
    Where datediff(mm, monthending, GETDATE()) = 1
    and DATEDIFF(mm,DischDate,monthending)>2)
    left join cte_EOMDenials d
    on p.unitnum=d.unitnum and p.patnum = d.patnum and p.insplan=d.iplan

Answer 1

您必须首先通过单个CTE介绍WITH的所有，然后您可以在最终查询中使用它们：

with Cte_LatestPatInfo as

(select max(a.LogID) as LastPatRec, p.unitnum, p.PatNum, a.iplan from
     rrscsql2.arhighdollar.dbo.tblarinfoHistory a
inner join rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
on a.patID=p.patID and a.LogID=p.LogID
where a.Active = 1
and a.ReasonCode is not null
group by  p.unitnum, p.PatNum, a.iplan),

cte_EOMDenials as
(select d.* from rrscsql2.Denials.dbo.tblDenialMonthEnd d 
Inner join rrscsql3.Facilities.dbo.vwFacilities f
on d.UnitNum = f.UnitNum and f.Owner like '%LifePoint%'
Inner join rrscsql2.Denials.dbo.tblDispositionDictionary t
on d.disposition=t.disposition and DispositionType like'O%'
Where datediff(mm, monthending, GETDATE()) = 1
and DATEDIFF(mm,DischDate,monthending)>2)

select *,rc.Description from  rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
inner join cte_LatestPatInfo li
on p.PatNum=li.PatNum and p.UnitNum=li.UnitNum and p.LogID = li.LastPatRec
inner join  rrscsql2.arhighdollar.dbo.tblarinfoHistory ah 
on ah.LogID=p.LogID and ah.iplan = li.iplan and p.PatID=ah.PatID
left join rrscsql2.ARHighDollar.dbo.tblReasonCodes rc 
on ah.ReasonCode=rc.ReasonCode
left join cte_EOMDenials d
on p.unitnum=d.unitnum and p.patnum = d.patnum and p.insplan=d.iplan

Answer 2

声明似乎没有加入两个CTE。如果你想加入两个ctes，你可以像下面的例子那样实现它

;WITH CTE_1
as
( select field1, field2... from sometable),
CTE_2 
as
(select field1, field2... from sometable),
select  a.field1, a.field2, b.field1, b.field2 
from CTE_1 a left join CTE_2 b on a.field1 = b.field1;

您会注意到首先定义了两个ctes，用逗号（，）分隔，然后在select语句中使用。
