TSQL -- 在 SSMS 中的一行上显示两个查询的结果

Question

我正在使用 TSQL，SSMS v.17.9.1 底层数据库是 Microsoft SQL Server 2014 SP3

出于显示目的，我想连接两个查询的结果：

SELECT TOP 1 colA as 'myCol1' FROM tableA
--
SELECT TOP 1 colB  as 'myCol2' FROM tableB

并在 SSMS 的一行中显示查询结果。（TOP 1 指令有望保证每个查询的结果数量相同，这将有助于将它们一起显示。如果这可以推广到 TOP 10 per query 这也会有所帮助）

Answer 1

这应该适用于任意数量的行，它假设您要按显示的列中的值排序

        With 
        TableA_CTE AS
        (
        SELECT TOP 1 colA as myCol1
        ,Row_Number() OVER (ORDER BY ColA DESC)  AS RowOrder 
        FROM tableA
        ),
        TableB_CTE AS
        (
        SELECT TOP 1 colB as myCol2
        ,Row_Number() OVER (ORDER BY ColB DESC)  AS RowOrder 
        FROM tableB
        )
        SELECT A.myCol1, B.MyCol2
        FROM TableA_CTE AS A
        INNER JOIN TableB_CTE AS B
           ON A.RowOrder = B.RowOrder

Answer 2

目前接受的答案有两个问题： I) 行前缺少逗号："Table B As" II) TSQL 写的好像是递归的，所以我重新写成非递归的方式：

这是对实际在 T-SQL:

中有效的已接受答案的修改

USE [Database_1];

 With 
   CTE_A AS
    (
    SELECT TOP 1 [Col1] as myCol1 
    ,Row_Number() OVER (ORDER BY [Col2] desc)  AS RowOrder 
    FROM [TableA]
    )
    ,
    CTE_B AS
    (
    SELECT TOP 1 [Col2] as myCol2
    ,Row_Number() OVER (ORDER BY [Col2] desc)  AS RowOrder 
    FROM  [TableB] 
    )
    SELECT A.myCol1, B.myCol2
    FROM CTE_A AS A
    INNER JOIN CTE_B  AS B
       ON ( A.RowOrder = B.RowOrder)
