mysql - 如何从 SQL QUERY 的计算中剔除 WEEKENDS？

我有 SQL 查询，它返回上一年某些工人的平均利用率。

SELECT Name, AVG (hsum)
FROM
(
    SELECT Name,sum((number_hours)/8)*100 AS hsum
    FROM
    T1
    WHERE name='PERSON_A' and bookeddate>='2012-01-01' and booked_date<='2012-12-31'
    GROUP BY name,booked_date
) t

添加DAYOFWEEK()到您的WHERE条款：

 AND DAYOFWEEK(booked_date) <> 1 AND DAYOFWEEK(booked_date)<>7
