Sql server 无法在sql上绑定多部分标识符，其大小写为

大家好，我有一个sql查询，其中我使用case when和internal join

我面临的问题是我得到了多部分标识符的错误

这是我的sql查询

SELECT 
CASE when row_num = 1 THEN bill_id ELSE NULL 
END as bill_id, listinvoice.sonvinid,
listinvoice.date, listinvoice.brandname,listinvoice.venue,listinvoice.zone,
listinvoice.location,
listinvoice.instructore,listinvoice.paymentid,listinvoice.amount
FROM (
select bill_id, row_number()
 over
 (partition by bill_id order by listinvoice.date asc)
  row_num, listinvoice.sonvinid, tid, listinvoice.date
  , listinvoice.brandname,listinvoice.venue,
  listinvoice.zone,listinvoice.location,
  listinvoice.instructore,paymentid,amount
from listinvoice
inner join sonvininsert
on 
sonvininsert.sonvinid=listinvoice.sonvinid
 where 
tid in (select tid from trainerdetails where empname='andrew charles')
and listinvoice.[date] between
'2015-02-02' and '2017-02-02'
)data

还有我的错误

Msg 4104，16级，状态1，第1行-多部分标识符 无法绑定“listinvoice.sonvinid”。味精4104，16级，状态 1，第1行无法找到多部分标识符“listinvoice.date” 跳跃Msg 4104，16级，状态1，第1行-多部分标识符 无法绑定“listinvoice.brandname”。味精4104，16级，状态 1，第1行无法找到多部分标识符“listinvoice.Vincement” 跳跃Msg 4104，16级，状态1，第1行-多部分标识符 无法绑定“listinvoice.zone”。味精4104，16级，状态1， 第1行无法找到多部分标识符“listinvoice.location” 跳跃Msg 4104，16级，状态1，第1行-多部分标识符 无法绑定“listinvoice.Instructor”。味精4104，16级， 状态1，第1行多部分标识符“listinvoice.paymentid” 无法约束。Msg 4104，16级，状态1，第1行，多部件 无法绑定标识符“listinvoice.amount”

对此可能的修复方法是什么？

除了内部查询的别名外，您的查询是正确的，需要进行一次更改：

SELECT 
    CASE 
        when row_num = 1 
        THEN bill_id 
        ELSE NULL 
    END as bill_id, 
    listinvoice.sonvinid,
    listinvoice.date,
    listinvoice.brandname,
    listinvoice.venue,
    listinvoice.zone,
    listinvoice.location,
    listinvoice.instructore,
    listinvoice.paymentid,
    listinvoice.amount
FROM (
    select 
        bill_id, 
        row_number() over
            (partition by bill_id order by listinvoice.date asc) row_num, 
        listinvoice.sonvinid, 
        tid, 
        listinvoice.date , 
        listinvoice.brandname,
        listinvoice.venue,  
        listinvoice.zone,
        listinvoice.location,
        listinvoice.instructore,
        paymentid,
        amount
    from listinvoice
        inner join sonvininsert
            on 
            sonvininsert.sonvinid=listinvoice.sonvinid
    where 
        tid in 
            (
                select 
                    tid 
                from trainerdetails 
                where empname='andrew charles'
            )
    and listinvoice.[date] 
        between '2015-02-02' and '2017-02-02'
        )listinvoice -- change required here to correct the alias

您的

SELECT

语句是从名为

data

的派生表中提取的，因此您需要适当地引用表名

尝试将第一个

SELECT

s更改为

data。columnnames

来自

listinvoice。columnnames

来自您发布的内容，此内容根本不需要子查询。此处的数据是什么？@SeanLange此内容与主题无关，但是您对查询和聚合有着非常深刻的理解，一般来说，您不会看到数据样本。。。真是太神奇了。你是怎么做到的？我是正确的。我没有看到您在外部查询中引用行号列的部分。但其他人已经回答了你的问题。

SELECT 
CASE when row_num = 1 THEN bill_id ELSE NULL 
END as bill_id, data.sonvinid,
data.date, data.brandname,data.venue,data.zone,
data.location,
data.instructore,data.paymentid,data.amount
FROM (
select bill_id, row_number()
 over
 (partition by bill_id order by listinvoice.date asc)
  row_num, listinvoice.sonvinid, tid, listinvoice.date
  , listinvoice.brandname,listinvoice.venue,
  listinvoice.zone,listinvoice.location,
  listinvoice.instructore,paymentid,amount
from listinvoice
inner join sonvininsert
on 
sonvininsert.sonvinid=listinvoice.sonvinid
 where 
tid in (select tid from trainerdetails where empname='andrew charles')
and listinvoice.[date] between
'2015-02-02' and '2017-02-02'
)data -- here is where you named your table
