为什么在SQL Server查询中尝试联接表时出错

我写了下面的查询来收集与卡车司机收入相关的数据。主查询和联接查询都能正常工作。但是，当我合并它们时，我会得到一个错误

Msg 4104，16级，状态1，第37行 无法绑定多部分标识符tn.ctripnumber

与tRev.ctripnumber有关=tn.ctripnumber。我尝试过使用revenue表名和tRev别名

select 
    tn.ctripnumber as "Load Number",
    tr.cresourcedesc as "Carrier/Driver",
    tr.resourcetype as "Resource Type",
    tn.cfirmorigin as "Pickup Origin",
    tn.corigaddress as "Origin Address",
    tn.corigcity as "Origin City",
    tn.corigstate as "Origin State",
    tn.corigzip as "Origin Zip",
    tn.dorigappt_start as "Scheduled Arrival Date",
    tn.dorigappt_end as "Scheduled Late Arrival Date",
    tn.dtripstartdate as "Actual Arrival Date",
    datediff(minute,tn.dorigappt_start,tn.dtripstartdate) as "Arrival Diff",
    (case when tn.dtripstartdate-tn.dorigappt_start < 0 then 'Early' when tn.dorigappt_start-tn.dtripstartdate = 0 then 'On-time' else 'Late' end) as Arrival_Rank,
    tn.cfirmdestination as "Delivery Destination",
    tn.cdestaddress as "Destination Address",
    tn.cdestcity as "Destination City",
    tn.cdeststate as "Destination State",
    tn.cdestzip as "Destination Zip",
    tn.ddestappt_start as "Scheduled Delivery Date",
    tn.ddestappt_end as "Scheduled Late Delivery Date",
    tn.ddeliverydate as "Actual Delivery Date",
    datediff(minute,tn.ddestappt_start,tn.ddeliverydate) as "Delivery Diff",
    (case when tn.ddeliverydate-tn.ddestappt_start < 0 then 'Early' when tn.ddeliverydate-tn.ddestappt_start = 0 then 'On-time' else 'Late' end) as "Delivery Rank",
    tn.nideadheadmiles as "Deadhead Miles",
    tn.niloadedmiles as "Loaded Miles",
    tn.nideadheadmiles + tn.niloadedmiles as "Total Miles"
from 
    tripnumber tn,tripresources tr
inner join
    (select  
         r.ctripnumber, sum(Revenue_Subtotal) as "Revenue" 
     from 
         (select 
              r.ctripnumber, r.cmethod, sum(r.curevenue) as Revenue_Subtotal
          from 
              revenuedtl r 
          where 
              r.cmethod in (select distinct r.cmethod from revenuedtl r)
          group by 
              r.ctripnumber, r.cmethod) r
     --where r.cmethod like 'BROK%'
     group by 
         r.ctripnumber) tRev on tRev.ctripnumber = tn.ctripnumber
where 
    tn.ctripnumber = tr.ctripnumber
    --and tn.ctripnumber = '324412'
    and tr.resourcetype in ('D','M')
    and tn.dtripstartdate >= '2018-12-01 00:00:00.000'
    and tn.dtripstartdate < '2019-01-01 00:00:00.000'

这是您的from条款：

简单规则：在FROM子句中不要使用逗号。始终使用正确、明确、标准的联接语法

因此，请使用适当的联接重写此代码：

你的错误就会消失

查询失败的技术原因是，的作用域规则不同于交叉联接。实际上，您可以用交叉连接替换逗号来解决问题。但正确的解决方案是正确地表示联接。

这是一条不适合在评论部分的评论。尽量不要把旧的学校联谊会和现代联谊会混为一谈。这使得读取和调试更加困难

例如，更改此项：

from tripnumber tn,tripresources tr
where tn.ctripnumber = tr.ctripnumber

为此：

from tripnumber tn
join tripresources tr on tn.ctripnumber = tr.ctripnumber
