2需要加入SELECT语句

Question

我需要加入这两个声明，但似乎我错误地使用了UNION和/或JOIN：

SELECT ElapsedTime2 AS 'All Waits/Walks' 
FROM TABLE_TEST2 
WHERE StepID = '1081' 
ORDER BY ElapsedTime2

SELECT ElapsedTime2 AS 'Arrives in Line' 
FROM TABLE_TEST2 
WHERE StepID = '1079' 
ORDER BY ElapsedTime2

希望它应该像这样聚集在一起：

All Waits/Walks Arrives in Line
6               9
8               12
11              15

感谢您的帮助!!我随着时间的流逝学习。
