Question

如何获得以下 TSQL 查询结果的转置 UNION

SELECT TOP 1 Column_A FROM table1

SELECT TOP 1 Column_B FROM table2

SELECT TOP 1 Column_C FROM table3

这样输出将是一行 3 列，每列有一个值：

[Column_A] [Column_B] [Column_C]

Answer 1

像这样：

Select 
 (SELECT TOP 1 Column_A FROM table1) as 'Column_A',
 (SELECT TOP 1 Column_B FROM table2) as 'Column_B',
 (SELECT TOP 1 Column_C FROM table3) as 'Column_C'
