从两列结果集创建图表

Question

我需要创建一个 sql 查询来分析 atendimetos 员工

我的目标是通过此查询创建一个显示总分钟数的图表，称为：有多少人达到了 120 分钟（非常服务时间）和有多少低于 120 分钟（正常通话）在 C# 图表中使用

最简单的方法是生成两列，对吗？

我该怎么做？我想不出解决办法。

SELECT SUM(CallDuration)
FROM CallsFromCustomers
WHERE  DATE(CallDate) Between'2015-06-01' And '2015-06-31'
AND CallDuration < 120
UNION 
SELECT
SUM(CallDuration)
FROM CallsFromCustomers
WHERE  DATE(CallDate) Between '2015-06-01' And '2015-06-31'
AND CallDuration >= 120

结果

SUM(CallDuration)|
            5584 |
            759  |

Answer 1

SELECT 
(SELECT COUNT(*)
FROM CallsFromCustomers
WHERE  DATE(CallDate) Between'2015-06-01' And '2015-06-31'
AND CallDuration < 120) AS ShortCalls, 
(SELECT COUNT(*)
FROM CallsFromCustomers
WHERE  DATE(CallDate) Between '2015-06-01' And '2015-06-31'
AND CallDuration >= 120) AS LongCalls
