我在SQL Server中创建了3个查询,我只是想知道我是否可以有1个查询而不是这3个查询？

这些是我的3个查询:

SELECT COUNT(JONumber) JANUARY
FROM JobOrders
WHERE JODate BETWEEN '01/01/2017' AND '01/31/2017'

SELECT COUNT(JONumber) FEBRUARY
FROM JobOrders
WHERE JODate BETWEEN '02/01/2017' AND '02/28/2017'

SELECT COUNT(JONumber) TOTAL
FROM JobOrders
WHERE JODate BETWEEN '01/01/2017' AND '02/28/2017'
