简化如下SQL:SELECT e.empName,e.ts,f.archermindNum,f.departureTimeMax,f.departureTimeMin,f.departureTimeAvg,f.departureTimeTotal from (select b.empName,count(clockDate) as ts from (SELECT empName,clockDate,COUNT(clockDate) from r_empmachineclock_data_analysis where clockDate between "2023-05-01" and "2023-05-30" GROUP BY empName,clockDate) b group by b.empName) e ,(select max(departureTime) as departureTimeMax,min(departureTime) as departureTimeMin,ROUND(avg(departureTime)) as departureTimeAvg,sum(departureTime) as departureTimeTotal,empName,archermindNum from r_empmachineclock_data_analysis where departureTime >0 and clockDate between "2023-05-01" and "2023-05-30" group by archermindNum) f where e.empName = f.empName

以下是简化后的SQL查询语句：

SELECT 
    e.empName, 
    e.ts, 
    f.archermindNum, 
    MAX(f.departureTime) AS departureTimeMax, 
    MIN(f.departureTime) AS departureTimeMin, 
    ROUND(AVG(f.departureTime)) AS departureTimeAvg, 
    SUM(f.departureTime) AS departureTimeTotal 
FROM 
    (
        SELECT 
            empName, 
            COUNT(clockDate) AS ts 
        FROM 
            (
                SELECT 
                    empName, 
                    clockDate, 
                    COUNT(clockDate) 
                FROM 
                    r_empmachineclock_data_analysis 
                WHERE 
                    clockDate BETWEEN "2023-05-01" AND "2023-05-30" 
                GROUP BY 
                    empName, 
                    clockDate
            ) b 
        GROUP BY 
            empName
    ) e 
    JOIN (
        SELECT 
            empName, 
            archermindNum, 
            departureTime 
        FROM 
            r_empmachineclock_data_analysis 
        WHERE 
            departureTime > 0 
            AND clockDate BETWEEN "2023-05-01" AND "2023-05-30"
    ) f 
    ON e.empName = f.empName 
GROUP BY 
    e.empName, 
    e.ts, 
    f.archermindNum

该查询使用了两个子查询，其中第一个子查询计算了每个员工的工作天数，第二个子查询计算了每个员工的出勤情况。通过内连接将这两个结果集合并，并使用GROUP BY对结果进行分组，以便得到每个员工的出勤统计信息。
