WITH 子句语法错误 - 使用外部选择时

Question

我在下面创建了一个 sql，当我试图将它放在外部选择下时，它将只显示从下面的 WITH 子句查询呈现的结果，它在 sql server 中给了我错误，在那里工作正常与甲骨文。 我不想创建一个视图，我想把它放在合并语句中的输出下面...

select custno, slipno, category, donation, unique_nm from
( 
-- Here it is throwing error
with  got_debit_custno (custno, slipno, category, donation, debit_custno)  as
(
    select  custno, slipno, category, donation
    ,   case
          when category = 'CREDIT'
          then 'N/A'
          else custno
        end
    from    a
)
,  prep (custno, slipno, category, donation, debit_custno, rn, rdt) as
(
    select  dc.*
    ,   row_number ()  over (partition by debit_custno, category order by donation, slipno)
    ,       sum (donation) over (partition by debit_custno, category order by donation, slipno)
    from    got_debit_custno dc
)
,  r (custno, slipno, category, donation, debit_custno, rn, rdt, mn) as
(
    select  custno, slipno, category, donation, debit_custno
    ,       case
            when rn = max(rn) over (partition by debit_custno, category)
            then rn
        end
    ,       rdt, 1
    from    prep
    where   rdt <= 27000 or rn = 1
 union all
    select  p.custno, p.slipno, p.category, p.donation, p.debit_custno
    ,       case
            when p.rn = max(p.rn) over (partition by p.debit_custno, p.category)
            then p.rn
        end
    ,       p.rdt, r.mn + 1

WITH 必须是查询的第一个关键字。前面的语句必须被; 终止为：

    ;WITH got_debit_custno (custno, slipno, category, donation, debit_custno)  as
    (
        select  custno, slipno, category, donation
        ,   case
              when category = 'CREDIT'
              then 'N/A'
              else custno
            end
        from    a
    )
    ,  prep (custno, slipno, category, donation, debit_custno, rn, rdt) as
    (
        select  dc.*
        ,   row_number ()  over (partition by debit_custno, category order by donation, slipno)
        ,       sum (donation) over (partition by debit_custno, category order by donation, slipno)
        from    got_debit_custno dc
    )
    ,  r (custno, slipno, category, donation, debit_custno, rn, rdt, mn) as
    (
        select  custno, slipno, category, donation, debit_custno
        ,       case
                when rn = max(rn) over (partition by debit_custno, category)
                then rn
            end
        ,       rdt, 1
        from    prep
        where   rdt <= 27000 or rn = 1
     union all
        select  p.custno, p.slipno, p.category, p.donation, p.debit_custno
        ,       case
                when p.rn = max(p.rn) over (partition by p.debit_custno, p.category)
                then p.rn
            end
        ,       p.rdt, r.mn + 1
        from    prep p
        join    r    on  p.debit_custno = r.debit_custno
                 and p.category = r.categoRy
                 and p.rn > r.rn
                             and (p.rdt <= r.rdt + 27000 or p.rn = r.rn + 1)
    )
    select    custno, slipno, category, donation
    ,         dense_rank () over (order by debit_custno, category, mn) as unique_nm
    from      r
    order by  custno, unique_nm, donation
