合併行SQL查詢特定

Question

我需要一些幫助來開發將組合相同客戶端的行的查詢。基本上我有一個客戶端，有一個稅務經理，一個審計經理，一個客戶經理等。

到目前爲止我已經使用的代碼，我能夠拉起信息，但它吐出了幾行同一客戶端對於每種類型的經理

圖片上的示例（帶有代碼和結果）。我在下面添加了一個鏈接，它不會讓我直接添加圖片。

Here is the link of the screenshot to get a better idea, it wouldn't let me add a picture here!!

的代碼如下：

select ocr.staffcode as OCR, clientcode, clientname, 
case when cs.ServIndex = 'TAXCOMP' then tax.StaffCode else '-' end as 'Tax', 
case when cs.ServIndex = 'AUDIT' then audit.staffcode else '-' end as 'Audit', 
case when cs.ServIndex = 'REVIEW' then review.staffcode else '-' end as 'Review', 
case when cs.ServIndex = 'COMP' then comp.staffcode else '-' end as 'Comp', 
case when cs.ServIndex = 'RandE' then rande.staffcode else '-' end as 'R&E', 
case when cs.ServIndex = 'ACCTG' then acctg.staffcode else '-' end as 'Acctg', 
case when cs.ServIndex = 'VMA' then vma.staffcode else '-' end as 'BV', 
case when cs.ServIndex = 'LIT' then lit.staffcode else '-' end as 'Lit', 
case when cs.ServIndex = 'FORENSIC' then lit.staffcode else '-' end as 'Forensics', 
case when cs.ServIndex = 'CONS' then lit.staffcode else '-' end as 'Consulting' 
from tblEngagement e 
inner join tblClientServices cs on cs.ContIndex = e.contindex 
left outer join tblStaff ocr on ocr.StaffIndex = e.ClientPartner 
left outer join tblStaff tax on tax.StaffIndex = cs.ServManager 
left outer join tblStaff audit on audit.StaffIndex = cs.ServManager 
left outer join tblStaff review on review.StaffIndex = cs.ServManager 
left outer join tblStaff comp on comp.StaffIndex = cs.ServManager 
left outer join tblStaff rande on rande.StaffIndex = cs.ServManager 
left outer join tblStaff acctg on acctg.StaffIndex = cs.ServManager 
left outer join tblStaff vma on vma.StaffIndex = cs.ServManager 
left outer join tblStaff lit on lit.StaffIndex = cs.ServManager 
left outer join tblStaff fore on fore.staffindex = cs.ServManager 
where e.ContIndex < 900000 and cs.ServActPos = 1 and ClientStatus in ('ACTIVE','SUSPENDED') 
order by ClientCode 

我希望能夠只是將所有這些相同的OCR，Clietcode，客戶名稱的一排顯示的稅務經理，審計經理，審查經理等全部在一行......如果沒有經理爲其中一個顯示「 - 」，就像我在我的例子中那樣。我一直在讀幾個地方，試圖做自己，但沒有運氣。任何人都可以幫助我指引正確的方向？

Answer 1

嘗試通過客戶端進行分組，從而消除重複項，最大化案例列並在此之後用' - '填充NULL。但下面的代碼將只顯示一個管理每個類別。所以應該有兩個審計經理，只有一個會被這個返回：

select ocr.staffcode as OCR, clientcode, clientname, 
coalesce(max(case when cs.ServIndex = 'TAXCOMP' then tax.StaffCode end),'-') as 'Tax', 
coalesce(max(case when cs.ServIndex = 'AUDIT' then audit.staffcode end),'-') as 'Audit', 
coalesce(max(case when cs.ServIndex = 'REVIEW' then review.staffcode end),'-') as 'Review', 
coalesce(max(case when cs.ServIndex = 'COMP' then comp.staffcode end),'-') as 'Comp', 
coalesce(max(case when cs.ServIndex = 'RandE' then rande.staffcode end),'-') as 'R&E', 
coalesce(max(case when cs.ServIndex = 'ACCTG' then acctg.staffcode end),'-') as 'Acctg', 
coalesce(max(case when cs.ServIndex = 'VMA' then vma.staffcode end),'-') as 'BV', 
coalesce(max(case when cs.ServIndex = 'LIT' then lit.staffcode end),'-') as 'Lit', 
coalesce(max(case when cs.ServIndex = 'FORENSIC' then lit.staffcode end),'-') as 'Forensics', 
coalesce(max(case when cs.ServIndex = 'CONS' then lit.staffcode end),'-') as 'Consulting' 
from tblEngagement e 
inner join tblClientServices cs on cs.ContIndex = e.contindex 
left outer join tblStaff ocr on ocr.StaffIndex = e.ClientPartner 
left outer join tblStaff tax on tax.StaffIndex = cs.ServManager 
left outer join tblStaff audit on audit.StaffIndex = cs.ServManager 
left outer join tblStaff review on review.StaffIndex = cs.ServManager 
left outer join tblStaff comp on comp.StaffIndex = cs.ServManager 
left outer join tblStaff rande on rande.StaffIndex = cs.ServManager 
left outer join tblStaff acctg on acctg.StaffIndex = cs.ServManager 
left outer join tblStaff vma on vma.StaffIndex = cs.ServManager 
left outer join tblStaff lit on lit.StaffIndex = cs.ServManager 
left outer join tblStaff fore on fore.staffindex = cs.ServManager 
where e.ContIndex < 900000 and cs.ServActPos = 1 and ClientStatus in ('ACTIVE','SUSPENDED') 
group by ocr.staffcode, clientcode, clientname 
order by ClientCode

此代碼也可以，我上面非常相似，Brett的

select ocr.staffcode as OCR, clientcode, clientname, 
max(case when cs.ServIndex = 'TAXCOMP' then tax.StaffCode else '-' end) as 'Tax', 
max(case when cs.ServIndex = 'AUDIT' then audit.staffcode else '-' end) as 'Audit', 
max(case when cs.ServIndex = 'REVIEW' then review.staffcode else '-' end) as 'Review', 
max(case when cs.ServIndex = 'COMP' then comp.staffcode else '-' end) as 'Comp', 
max(case when cs.ServIndex = 'RandE' then rande.staffcode else '-' end) as 'R&E', 
max(case when cs.ServIndex = 'ACCTG' then acctg.staffcode else '-' end) as 'Acctg', 
max(case when cs.ServIndex = 'VMA' then vma.staffcode else '-' end) as 'BV', 
max(case when cs.ServIndex = 'LIT' then lit.staffcode else '-' end) as 'Lit', 
max(case when cs.ServIndex = 'FORENSIC' then lit.staffcode else '-' end) as 'Forensics', 
max(case when cs.ServIndex = 'CONS' then lit.staffcode else '-' end) as 'Consulting' 
from tblEngagement e 
inner join tblClientServices cs on cs.ContIndex = e.contindex 
left outer join tblStaff ocr on ocr.StaffIndex = e.ClientPartner 
left outer join tblStaff tax on tax.StaffIndex = cs.ServManager 
left outer join tblStaff audit on audit.StaffIndex = cs.ServManager 
left outer join tblStaff review on review.StaffIndex = cs.ServManager 
left outer join tblStaff comp on comp.StaffIndex = cs.ServManager 
left outer join tblStaff rande on rande.StaffIndex = cs.ServManager 
left outer join tblStaff acctg on acctg.StaffIndex = cs.ServManager 
left outer join tblStaff vma on vma.StaffIndex = cs.ServManager 
left outer join tblStaff lit on lit.StaffIndex = cs.ServManager 
left outer join tblStaff fore on fore.staffindex = cs.ServManager 
where e.ContIndex < 900000 and cs.ServActPos = 1 and ClientStatus in ('ACTIVE','SUSPENDED') 
group by ocr.staffcode, clientcode, clientname 
order by ClientCode
