Answer 1

您可以在两个查询之间使用UNION ALL，例如

SELECT ...
FROM ...
WHERE...

UNION ALL

SELECT ...
FROM ....
WHERE...

您可以在此处了解UNION和UNION ALL中的差异：What is the difference between UNION and UNION ALL?

您也可以使用CTE - 如果您有可以加入的列，例如

;WITH Query1 AS
(
 SELECT Column1
 FROM ...
)
,Query2 AS
( 
 SELECT Column1
 FROM ...
)
SELECT     *
FROM       Query1 AS Q1
INNER JOIN Query2 AS Q2 ON Q1.Column1 = Q2.Column1

Answer 2

一种方法是使用UNION ALL方法，如其他人建议的那样。

ServletFilter

对于您的情况，可能会对连接条件进行大小写修改。请尝试以下方法：

(Query 1)
union all
(Query 2)

将两个select语句合并为一个
