Question

我試圖與工會都結合起來，查詢：

use SalesDWH 
go 


select cast(COUNT([specimen id]) as varchar) +'|'+[practice name]+'|'+b.[mlis practice id]+'|'+[practice code]+'|'+[Requesting Physician]+'|'+c.salesrep+'|'+ 
    cast(c.dateestablished as varchar)+'|'+ c.practicecity+'|'+c.practicestate 
from quicklabdump a 
    inner join qlmlismapping b 
    on (b.[quiklab practice code] = a.[practice code]) 
    inner join PracticeandPhysician c 
    on (a.[Requesting Physician]=c.doctorfirstname+' '+c.DOCTORLASTNAME 
     and a.[practice code]=c.practicecode) 
where DATEPART(yy, [DATE entered]) = 2011 
    and DATEPART(mm, [DATE entered]) = 12 
group by a.[practice name],b.[mlis practice id],a.[practice code], 
    a.[Requesting Physician],c.salesrep,c.dateestablished, c.practicecity,c.practicestate 
order by COUNT([specimen id]) desc 

union all 

select cast(COUNT([specimen id]) as varchar) +'|'+[practice name]+'|'+b.[mlis practice id]+'|'+[practice code]+'|'+[Requesting Physician]+'|'+c.salesrep+'|'+ 
    cast(c.dateestablished as varchar)+'|'+ c.practicecity+'|'+c.practicestate 
from quicklabdump a 
    inner join qlmlismapping b 
    on (b.[quiklab practice code] = a.[practice code]) 
    inner join PracticeandPhysician c 
    on (a.[Requesting Physician]=c.doctorfirstname+' '+c.DOCTORLASTNAME 
     and a.[practice code]=c.practicecode) 
where DATEPART(yy, [DATE entered]) = 2011 
    and DATEPART(mm, [DATE entered]) = 11 
group by a.[practice name],b.[mlis practice id],a.[practice code], 
    a.[Requesting Physician],c.salesrep,c.dateestablished, c.practicecity,c.practicestate 
order by COUNT([specimen id]) desc 

但我收到此錯誤：

Msg 156, Level 15, State 1, Line 2 
Incorrect syntax near the keyword 'union'. 

我在做什麼錯？

Answer 1

除去第一

order by COUNT([specimen id]) desc 

或做到這一點：

select cDATEPART(mm, [DATE entered]) as Month, cast(COUNT([specimen id]) as varchar) +'|'+[practice name]+'|'+b.[mlis practice id]+'|'+[practice code]+'|'+[Requesting Physician]+'|'+c.salesrep+'|'+ 
    cast(c.dateestablished as varchar)+'|'+ c.practicecity+'|'+c.practicestate 
from quicklabdump a 
    inner join qlmlismapping b 
    on (b.[quiklab practice code] = a.[practice code]) 
    inner join PracticeandPhysician c 
    on (a.[Requesting Physician]=c.doctorfirstname+' '+c.DOCTORLASTNAME 
     and a.[practice code]=c.practicecode) 
where DATEPART(yy, [DATE entered]) = 2011 
    and DATEPART(mm, [DATE entered]) in (11,12) 
group by DATEPART(mm, [DATE entered]), a.[practice name],b.[mlis practice id],a.[practice code], 
    a.[Requesting Physician],c.salesrep,c.dateestablished, c.practicecity,c.practicestate 
order by COUNT([specimen id]) desc 

你也可以這樣說

select CASE WHEN cDATEPART(mm, [DATE entered]) = 11 THEN 'The 11th Month' 
      WHEN cDATEPART(mm, [DATE entered]) = 12 THEN 'The 12th Month' END as [when], ... 

Answer 2

你order by只能走在最後聲明：

use SalesDWH 
go 


select cast(COUNT([specimen id]) as varchar) +'|'+[practice name]+'|'+b.[mlis practice id]+'|'+[practice code]+'|'+[Requesting Physician]+'|'+c.salesrep+'|'+ 
    cast(c.dateestablished as varchar)+'|'+ c.practicecity+'|'+c.practicestate 
from quicklabdump a 
    inner join qlmlismapping b 
    on (b.[quiklab practice code] = a.[practice code]) 
    inner join PracticeandPhysician c 
    on (a.[Requesting Physician]=c.doctorfirstname+' '+c.DOCTORLASTNAME 
     and a.[practice code]=c.practicecode) 
where DATEPART(yy, [DATE entered]) = 2011 
    and DATEPART(mm, [DATE entered]) = 12 
group by a.[practice name],b.[mlis practice id],a.[practice code], 
    a.[Requesting Physician],c.salesrep,c.dateestablished, c.practicecity,c.practicestate 

union all 

select cast(COUNT([specimen id]) as varchar) +'|'+[practice name]+'|'+b.[mlis practice id]+'|'+[practice code]+'|'+[Requesting Physician]+'|'+c.salesrep+'|'+ 
    cast(c.dateestablished as varchar)+'|'+ c.practicecity+'|'+c.practicestate 
from quicklabdump a 
    inner join qlmlismapping b 
    on (b.[quiklab practice code] = a.[practice code]) 
    inner join PracticeandPhysician c 
    on (a.[Requesting Physician]=c.doctorfirstname+' '+c.DOCTORLASTNAME 
     and a.[practice code]=c.practicecode) 
where DATEPART(yy, [DATE entered]) = 2011 
    and DATEPART(mm, [DATE entered]) = 11 
group by a.[practice name],b.[mlis practice id],a.[practice code], 
    a.[Requesting Physician],c.salesrep,c.dateestablished, c.practicecity,c.practicestate 
order by COUNT([specimen id]) desc 

這是因爲排序發生在結果集後達到，這是後結合。在最終返回之前，您無法訂購一套。
