Question

请您查看代码并注意我不能在“联盟”的任何一侧的主要Select Statement Query中使用“MYDELTOT”

代码：

select 
    'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID, 
    (select sum(DYN_PORDERDELS.DelQty) as MMTD 
     from DYN_PORDERDELS 
     where DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
    * 
from 
    DYN_PORDERSRS
inner join 
    DYN_PORDERS on DYN_PORDERS.id = DYN_PORDERSRS.RSOrderID
inner join 
    SYS_SUPPLIERS on SYS_SUPPLIERS.id = DYN_PORDERS.SupplierID
inner join 
    DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
where 
    DYN_PORDERSRS.RSDate <= '20151031'
    and DYN_PORDERS.Qnty >= MYDELTOT

union

select 
    'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID,
    (select sum(DYN_PORDERDELS.DelQty) as MMTD 
     from DYN_PORDERDELS 
     where DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
    * 
from 
    DYN_PORDERSRS
inner join 
    DYN_PORDERS on DYN_PORDERS.id = DYN_PORDERSRS.RSOrderID
inner join 
    SYS_SUPPLIERS on SYS_SUPPLIERS.id = DYN_PORDERS.SupplierID
inner join 
    DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
where 
    DYN_PORDERSRS.rsdate  >= '20151101' 
    and DYN_PORDERS.Qnty >= MYDELTOT

请帮忙

Answer 1

您可以尝试在以下内容中使用CTE：

 ;with cte as (
    select 'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID, 
    (select sum(DYN_PORDERDELS.DelQty) as MMTD from DYN_PORDERDELS where                           
    DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
    * from DYN_PORDERSRS
    inner join DYN_PORDERS on DYN_PORDERS.id=DYN_PORDERSRS.RSOrderID
    inner join SYS_SUPPLIERS on SYS_SUPPLIERS.id=DYN_PORDERS.SupplierID
    inner join DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
    where DYN_PORDERSRS.RSDate  <=  '20151031'
    union
    select 'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID,
    (select sum(DYN_PORDERDELS.DelQty) as MMTD from DYN_PORDERDELS where                         
    DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
    * from DYN_PORDERSRS
    inner join DYN_PORDERS on DYN_PORDERS.id=DYN_PORDERSRS.RSOrderID
    inner join SYS_SUPPLIERS on SYS_SUPPLIERS.id=DYN_PORDERS.SupplierID
    inner join DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
    where DYN_PORDERSRS.rsdate  >= '20151101' 
)
select * 
from cte
where Qnty >= MYDELTOT

你的sql看起来有点滑稽但是应该这样做.....今天第二个

SELECT q.* FROM
(
  select 'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID, DYN_PORDERS.Qnty,
  (select sum(DYN_PORDERDELS.DelQty) as MMTD from DYN_PORDERDELS where                           
  DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
  * from DYN_PORDERSRS
  inner join DYN_PORDERS on DYN_PORDERS.id=DYN_PORDERSRS.RSOrderID
  inner join SYS_SUPPLIERS on SYS_SUPPLIERS.id=DYN_PORDERS.SupplierID
  inner join DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
  where DYN_PORDERSRS.RSDate  <=  '20151031'
  union
  select 'POID' = DYN_PORDERS.ID, 'PSID' = SYS_SUPPLIERS.ID, DYN_PORDERS.Qnty,
  (select sum(DYN_PORDERDELS.DelQty) as MMTD from DYN_PORDERDELS where                         
  DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID) as MYDELTOT,
  * from DYN_PORDERSRS
  inner join DYN_PORDERS on DYN_PORDERS.id=DYN_PORDERSRS.RSOrderID
  inner join SYS_SUPPLIERS on SYS_SUPPLIERS.id=DYN_PORDERS.SupplierID
  inner join DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
  where DYN_PORDERSRS.rsdate  >= '20151101' 
) q
where 
  AND q.Qnty >= q.MYDELTOT

Answer 3

在WHERE条件之后应用别名，这意味着在应用条件时没有任何名称为MYDELTOT。

解决这个问题的一种方法是在子查询中创建别名，别名将与子查询级别的值相关联

select 'POID' = DYN_PORDERS.ID
     , 'PSID' = SYS_SUPPLIERS.ID
     , t.MYDELTOT
     , * 
from   DYN_PORDERSRS
       inner join DYN_PORDERS on DYN_PORDERS.id = DYN_PORDERSRS.RSOrderID
       inner join SYS_SUPPLIERS on SYS_SUPPLIERS.id = DYN_PORDERS.SupplierID
       inner join DYN_porderdels on DYN_PORDERS.ID = DYN_PORDERDELS.DelPOID
       CROSS APPLY (select sum(DYN_PORDERDELS.DelQty) as MYDELTOT
                    from   DYN_PORDERDELS 
                    where  DYN_PORDERDELS.DelPOID = DYN_PORDERS.ID
                   ) as t
where  DYN_PORDERSRS.rsdate <= '20151031' 
  and  DYN_PORDERS.Qnty >= t.MYDELTOT

SQL - 使用Sub Select语句中的列作为Main Select语句中的查询
