Question

运行以下代码时，出现错误：

子查询返回了多个值。当子查询紧随!=，<，<=，>，>=，(select top 1 convert(varchar,PaymentDate,103) from tblUTRDetail where CCN_No=CR.CCN_NO and CR.Claim_Status='Y' order by PaymentDate desc union all select top 1 convert(varchar,CreatedDate,103) from tblOpenCloseTrans where S_NO=CR.S_NO and OpenCloseType='C' and CR.Claim_Status='C' order by CreatedDate desc union all select top 1 convert(varchar,GENERATED_DATE,103) from tbldeficiencyletterTrans where S_NO=CR.S_NO and DEFICIENT_REPUDATION_FLAG='NC' and CR.Claim_Status='NC' order by GENERATED_DATE desc union all select top 1 convert(varchar,GENERATED_DATE,103) from tbldeficiencyletterTrans where S_NO=CR.S_NO and DEFICIENT_REPUDATION_FLAG='R' and CR.Claim_Status='RC' order by GENERATED_DATE desc union (select GENERATED_DATE from (Select s_no, convert (varchar,(GENERATED_DATE),103)as GENERATED_DATE ,row_number() over(partition by s_no order by s_no asc )as rw from tblDeficiencyLetterTrans b where DEFICIENT_REPUDATION_FLAG='NC' and s_no=CR.S_NO) T where rw=1) ) as SETTLEMENT_DATE,或将子查询用作表达式

当我添加最后一段代码时（请在并集后参阅）

start_date = driver.find_element_by_id('DayEndSumDate1').send_keys("30062019")

Answer 1

您的查询如下：

SELECT *

,(select 1 union all select 2
union all select 3
union all select 3
union (select 4)) as SETTLEMENT_DATE
FROM sys.tables

您正在选择一些列值，对于其中一个，您最多可以为一列SETTLEMENT_DATE返回4个值。

因此，您可以有多个值，其中一个值是期望值，这就是错误对您的意思。您必须选择：

如果要查看所有值，只需像这样为每列指定一个单独的名称

SELECT *

,select 1 as SETTLEMENT_DATE1
,
select 2 as SETTLEMENT_DATE2
,
select 3 as SETTLEMENT_DATE3
,
select 3 as SETTLEMENT_DATE4
,
(select 4) as SETTLEMENT_DATE5
FROM sys.tables

添加更多逻辑，以便每次从此子查询中仅返回一个值

(
    SELECT TOP 1 date
    FROM
    (

        (select top 1 convert(varchar,PaymentDate,103) from tblUTRDetail where CCN_No=CR.CCN_NO and CR.Claim_Status='Y' order by PaymentDate desc
        union all
        select top 1 convert(varchar,CreatedDate,103) from tblOpenCloseTrans where S_NO=CR.S_NO and OpenCloseType='C' and CR.Claim_Status='C' order by CreatedDate desc
        union all
        select top 1 convert(varchar,GENERATED_DATE,103) from tbldeficiencyletterTrans where S_NO=CR.S_NO and DEFICIENT_REPUDATION_FLAG='NC' and CR.Claim_Status='NC' order by GENERATED_DATE desc
        union all
        select top 1 convert(varchar,GENERATED_DATE,103) from tbldeficiencyletterTrans where S_NO=CR.S_NO and DEFICIENT_REPUDATION_FLAG='R' and CR.Claim_Status='RC' order by GENERATED_DATE desc
        union 
        (select GENERATED_DATE from  (Select s_no, convert (varchar,(GENERATED_DATE),103)as GENERATED_DATE ,row_number()
        over(partition by s_no order by s_no asc )as rw from tblDeficiencyLetterTrans b
        where DEFICIENT_REPUDATION_FLAG='NC' and s_no=CR.S_NO) T where rw=1)
        ) 
    )  DS (date)
    ORDER BY date
)
as SETTLEMENT_DATE,

create table #tempT (Material varchar(10),yyyyww  int,item_type  varchar(10),TPT int    )
-------------Insert---------------
insert into #tempT values('E123'    ,    201919 , 'Assembly'  , 7)
insert into #tempT values('E123'    ,    201919 , 'Assembly'  , 6)
insert into #tempT values('E123'    ,    201919 , 'Assembly'  , 7)
insert into #tempT values('E123'    ,    201919 , 'Assembly'  , 7)
insert into #tempT values('E123'    ,    201919 , 'FG'        , 2)
insert into #tempT values('E123'    ,    201919 , 'FG'        , 2)
insert into #tempT values('E123'    ,    201919 , 'FG'        , 1)
insert into #tempT values('E123'    ,    201919 , 'TEST'      , 7)
insert into #tempT values('E123'    ,    201919 , 'TEST'      , 4)

------------Output-------------
select Material ,ceiling(((sum((MaxTPT)))/7.00)+1)MaxTPT  
 from(select Material,item_type,case when item_type='Assembly' then max(TPT)
when item_type='fg' then max(TPT)
when item_type='TEST' then max(TPT) end MaxTPT from #tempT
group by Material,item_type)a`enter code here`
group by Material
