Question

有没有办法可以将这两个查询结合起来：

第一次查询

select top 100
WORK.pzInsKey,
WORK.pyID,
PARTY.MacID,
PARTY.OtherPartyID,
PARTY.CustomerEmail,
ACCOUNT.AccountNumber,
ACCOUNT.AccountName,
ACCOUNT.AdviserCode,
ACCOUNT.AdviserName,
ACCOUNT.DealerCode,
ACCOUNT.DealerName,
ACCOUNT.PrimaryAccount,
ACCOUNT.ProductCategory,
ACCOUNT.ProductCode,
ACCOUNT.ProductDescription,
ACCOUNT.RegisteredState,
DOCUMENT.UDOCID
from 
workTable WORK,
partyTable PARTY,
accountTable ACCOUNT,
documentTable DOCUMENT,
notesTable NOTES
where WORK.pzInsKey = PARTY.pxInsIndexedKey
and WORK.pzInsKey = ACCOUNT.pxInsIndexedKey
and WORK.pyID = DOCUMENT.CaseID

和第二次查询

SELECT top 100 
BusinessAreaTbl.businessarea,
ProcessTbl.process,
SubProcessTbl.subprocess
FROM workTable WORK
LEFT OUTER JOIN (SELECT DISTINCT Product_ID businessarea_id, Product businessarea from CaseTypesTable) BusinessAreaTbl
ON WORK.RequestBusinessArea#1 = BusinessAreaTbl.businessarea_id

LEFT OUTER JOIN (SELECT DISTINCT Process_ID, Process, Product_ID businessarea_id from CaseTypesTable) ProcessTbl
ON WORK.RequestProcess#1 = ProcessTbl.process_id
AND ProcessTbl.businessarea_id = WORK.RequestBusinessArea#1

LEFT OUTER JOIN (SELECT DISTINCT SubProcess_ID, SubProcess, Product_ID businessarea_id, Process_ID from CaseTypesTable) SubProcessTbl
ON WORK.RequestSubProcess#1 = SubProcessTbl.subprocess_id
AND SubProcessTbl.businessarea_id = WORK.RequestBusinessArea#1
AND SubProcessTbl.process_id = WORK.RequestProcess#1

它基本上是两个产生单独结果的查询，但每个查询都包含来自workTable的数据。在第二个查询中，workTable数据派生自CaseTypesTable。

我基本上只希望将businessarea，进程和子进程字段包含在第一个查询的结果中。

提前感谢您的帮助。

这应该有效：

(SELECT top 100
w.pzInsKey,
w.pyID,
p.MacID,
p.OtherPartyID,
p.CustomerEmail,
a.AccountNumber,
a.AccountName,
a.AdviserCode,
a.AdviserName,
a.DealerCode,
a.DealerName,
a.PrimaryAccount,
a.ProductCategory,
a.ProductCode,
a.ProductDescription,
a.RegisteredState,
d.UDOCID
FROM workTable w
LEFT JOIN partyTable p
ON w.pzInsKey = p.pxInsIndexedKey
LEFT JOIN accountTable a
ON w.pzInsKey = a.pxInsIndexedKey
LEFT JOIN documentTable d
ON w.pyID = d.CaseID)
UNION 
(SELECT top 100 
ba.businessarea,
pr.process,
spr.subprocess
FROM workTable w

LEFT OUTER JOIN (SELECT DISTINCT Product_ID businessarea_id, Product businessarea from CaseTypesTable) BusinessAreaTbl ba
ON w.RequestBusinessArea#1 = ba.businessarea_id

LEFT OUTER JOIN (SELECT DISTINCT Process_ID, Process, Product_ID businessarea_id from CaseTypesTable) ProcessTbl pr
ON w.RequestProcess#1 = pr.process_id
AND pr.businessarea_id = w.RequestBusinessArea#1

LEFT OUTER JOIN (SELECT DISTINCT SubProcess_ID, SubProcess, Product_ID businessarea_id, Process_ID from CaseTypesTable) SubProcessTbl spr
ON w.RequestSubProcess#1 = spr.subprocess_id
AND spr.businessarea_id = w.RequestBusinessArea#1
AND spr.process_id = w.RequestProcess#1))

使用关键字UNION合并两个或多个单独的SELECT语句。

将两个SQL查询与多个表和左连接组合在一起
