Question

如何使用打开的查询正确加入查询？这是我的查询现在如何布局。作为OPENQUERY一部分的查询单独工作。

Select d.* from db.dbo.table d left join (select * from OPENQUERY(otherSource,' --working query SELECT... left join... inner join..') OQ ON d.col1 = OQ.col1

我正在捕捉错误'Incorrect syntax near 'ON'.

Answer 1

此语法对我有用：

select 
   a.id, b.ItemId, a.Name, b.[Description]
from 
   [A_Database]..tblA a
inner join 
   openquery([linkedServerDbName], 'select * from [B_Database]..[TableToJoin]') b
ON 
   a.id = b.ItemId

Answer 2

您可能需要撤消它，从OPENQUERY执行SELECT。所以类似的东西：
SELECT * FROM OPENQUERY（remotesource，'SELECT blahblah from tableA）A
RIGHT JOIN tableB B ON B.col1 = A.col1

SQL JOIN与OPENQUERY
