子查询sql的问题

  • 772

您好我收到此错误：

当不使用 EXISTS 引入子查询时，选择列表中只能指定一个表达式。

这是我当前的 SQL 查询：

DECLARE @UgpEntry VARCHAR(50)

SELECT @UgpEntry = UgpEntry FROM OITM t1 WHERE t1.ItemCode='CID-11418272385'

IF (@UgpEntry = -1)

SELECT
t1.ItemCode as sapitemcode
     , t1.CodeBars as Barcode
     , t1.ItemName as description
     ,LEFT(t1.ItemName,20) as short_description
     , 
           (select max(p.Price)
        from ITM1 p 
        where p.ItemCode = t1.ItemCode 
          and p.PriceList = 1) as [price_1]
     ,
         (SELECT T0.[ItemCode], T2.[U_NAME] as 'User that created Item', t0.updatedate

FROM AITM T0 inner join OUSR T2 on t0.usersign = t2.internal_K

WHERE T0.[ItemCode] = t1.ItemCode

group by T0.[ItemCode], T2.[U_NAME], t0.loginstanc, t0.updatedate

having t0.loginstanc = (select min(loginstanc) from AITM where itemcode = t0.loginstanc)),
     CASE t1.VatGourpSa when 'V0' THEN 4 when 'V1' THEN 1 WHEN 'V2' THEN 2 WHEN 'V3' THEN 3 END as TaxCode,t1.U_GRUPOA, t1.U_GRUPOB, t1.U_GRUPOC, t1.UgpEntry

FROM OITM t1
WHERE t1.ItemCode='CID-11418272385'
 
ELSE

SELECT t1.ItemCode as sapitemcode
     , t1.CodeBars as Barcode
     , t1.ItemName as description
     ,LEFT(t1.ItemName,20) as short_description
     , (select max(p.Price)
        from ITM9 p 
        where p.ItemCode = t1.ItemCode 
          and p.UomEntry = 1 and p.PriceList = 1) as [price_1mananitas],

           (select max(p.Price)
        from ITM1 p 
        where p.ItemCode = t1.ItemCode 
          and p.PriceList = 1) as [preciocajamananitas],
(select max(p.Price)
        from ITM9 p 
        where p.ItemCode = t1.ItemCode 
          and p.UomEntry = 1 and p.PriceList = 2) as [price_2cabra],
               (select max(p.Price)
        from ITM1 p 
        where p.ItemCode = t1.ItemCode 
          and p.PriceList = 2) as [preciocajacabra]

     , CASE t1.VatGourpSa when 'V0' THEN 4 when 'V1' THEN 1 WHEN 'V2' THEN 2 WHEN 'V3' THEN 3 END as TaxCode,t1.U_GRUPOA, t1.U_GRUPOB, t1.U_GRUPOC, t1.UgpEntry

FROM OITM t1
WHERE t1.ItemCode='CID-11418272385'

我刚刚添加了这个子查询：

(SELECT T0.[ItemCode], T2.[U_NAME] as 'User that created Item', t0.updatedate
    
    FROM AITM T0 inner join OUSR T2 on t0.usersign = t2.internal_K
    
    WHERE T0.[ItemCode] = t1.ItemCode
    
    group by T0.[ItemCode], T2.[U_NAME], t0.loginstanc, t0.updatedate
    
    having t0.loginstanc = (select min(loginstanc) from AITM where itemcode = t1.ItemCode))

当我单独运行它时，我会得到这样的结果：

我想要做的是在我的主查询中添加该选择，以便在原始查询中显示为新列。所以它应该像这样在末尾出现新列（T2.[U_NAME] 和 t0.updatedate）：

我错过了什么？
