Question

我试图匹配员工日程表与报告日程表的结果。我需要输出一个报告，显示所有报告以及分配给他们的人。我遇到麻烦的地方是基于星期几。

我的ReportSchedule表看起来像这样：

╔══════════════╦══════════════╦══════╦══════╦══════╦══════╦══════╦══════╦════╗
║ ReportID     ║ Time         ║ M    ║ Tu   ║ W    ║ Th   ║ F    ║ Sa   ║ Su ║
╠══════════════╬══════════════╬══════╬══════╬══════╬══════╬══════╬══════╬════╣
║ 1001         ║ 06:18:00     ║ 1    ║ 1    ║ 1    ║ 1    ║ 1    ║ 0    ║  0 ║
║ 1002         ║ 06:48:00     ║ 0    ║ 0    ║ 0    ║ 0    ║ 0    ║ 1    ║  1 ║
║ 1003         ║ 07:18:00     ║ 1    ║ 1    ║ 1    ║ 1    ║ 1    ║ 1    ║  1 ║

我的EmployeesSchedule表看起来像这样：

╔════════════╦══════════╦═════════════╦═══════════╦═══╦════╦═══╦════╦═══╦════╦════╗
║ EmployeeID ║ ReportID ║ ReportStart ║ ReportEnd ║ M ║ Tu ║ W ║ Th ║ F ║ Sa ║ Su ║  
╠════════════╬══════════╬═════════════╬═══════════╬═══╬════╬═══╬════╬═══╬════╬════╣

║      22001 ║     1002 ║ 05:00:00    ║ 12:00:00  ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  0 ║  0 ║

║      22002 ║     1001 ║ 06:00:00    ║ 14:00:00  ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║  
║      22002 ║     1002 ║ 06:00:00    ║ 14:00:00  ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║  
║      22002 ║     1003 ║ 06:00:00    ║ 14:00:00  ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║  
╚════════════╩══════════╩═════════════╩═══════════╩═══╩════╩═══╩════╩═══╩════╩════╝

基于上述内容我需要的是：

╔════════════╦══════════╦══════════╦═══╦════╦═══╦════╦═══╦════╦════╗
║ EmployeeID ║ ReportID ║   Time   ║ M ║ Tu ║ W ║ Th ║ F ║ Sa ║ Su ║
╠════════════╬══════════╬══════════╬═══╬════╬═══╬════╬═══╬════╬════╣
║      22001 ║     1001 ║ 06:18:00 ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  0 ║  0 ║
║      22002 ║     1002 ║ 06:48:00 ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║
║      22001 ║     1003 ║ 07:18:00 ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  0 ║  0 ║
║      22002 ║     1003 ║ 07:18:00 ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║
╚════════════╩══════════╩══════════╩═══╩════╩═══╩════╩═══╩════╩════╝

我正在运行的查询如下：

SELECT EmployeeSchedule.EmployeeID, ReportSchedule.ReportID, ReportSchedule.Time, 
    ReportSchedule.M, ReportSchedule.Tu, ReportSchedule.W, ReportSchedule.Th, ReportSchedule.F, ReportSchedule.Sa, ReportSchedule.Su
FROM ReportSchedule
    INNER JOIN EmployeeSchedule on ReportSchedule.ReportID = EmployeeSchedule.ReportID
WHERE (
        ReportSchedule.Time > EmployeeSchedule.ReportStart AND 
        ReportSchedule.Time < EmployeeSchedule.ReportEnd AND
        (
            (ReportSchedule.M=1) AND (ReportSchedule.M = EmployeeSchedule.M) OR 
            (ReportSchedule.Tu=1) AND (ReportSchedule.Tu = EmployeeSchedule.Tu) OR 
            (ReportSchedule.W=1) AND (ReportSchedule.W = EmployeeSchedule.W) OR 
            (ReportSchedule.Th=1) AND (ReportSchedule.Th = EmployeeSchedule.Th) OR 
            (ReportSchedule.F=1) AND (ReportSchedule.F = EmployeeSchedule.F) OR 
            (ReportSchedule.Sa=1) AND (ReportSchedule.Sa = EmployeeSchedule.Sa) OR 
            (ReportSchedule.Su=1) AND (ReportSchedule.Su = EmployeeSchedule.Su)
        )
    )

这回归的结果不是我所寻找的，因为它没有过滤员工没有做报告的一周中的日子。以下是返回的内容：

╔════════════╦══════════╦══════════╦═══╦════╦═══╦════╦═══╦════╦════╗
║ EmployeeID ║ ReportID ║   Time   ║ M ║ Tu ║ W ║ Th ║ F ║ Sa ║ Su ║
╠════════════╬══════════╬══════════╬═══╬════╬═══╬════╬═══╬════╬════╣
║      22001 ║     1001 ║ 06:18:00 ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  0 ║  0 ║
║      22002 ║     1002 ║ 06:48:00 ║ 0 ║  0 ║ 0 ║  0 ║ 0 ║  1 ║  1 ║
║      22001 ║     1003 ║ 07:18:00 ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  1 ║  1 ║
║      22002 ║     1003 ║ 07:18:00 ║ 1 ║  1 ║ 1 ║  1 ║ 1 ║  1 ║  1 ║
╚════════════╩══════════╩══════════╩═══╩════╩═══╩════╩═══╩════╩════╝

我需要做些什么来获得我正在寻找的结果？

Answer 1

添加where子句，其中report＆lt;＆gt; 0？此外，你在where语句中有报告id = report id - 我不确定这是必要的，因为那是你的join子句。还是sql的新手，所以我不确定。

Answer 2

问题解决了。

我将原始查询插入到临时表中，然后运行以下内容并返回所需的数据。

SELECT #Temp.EmployeeID, #Temp.ReportID, #Temp.Time, 
    CASE WHEN EmployeeSchedule.M = 0 THEN 0 ELSE 1 END AS M,
    CASE WHEN EmployeeSchedule.Tu = 0 THEN 0 ELSE 1 END AS Tu,
    CASE WHEN EmployeeSchedule.W = 0 THEN 0 ELSE 1 END AS W,
    CASE WHEN EmployeeSchedule.Th = 0 THEN 0 ELSE 1 END AS Th,
    CASE WHEN EmployeeSchedule.F = 0 THEN 0 ELSE 1 END AS F,
    CASE WHEN EmployeeSchedule.Sa = 0 THEN 0 ELSE 1 END AS Sa,
    CASE WHEN EmployeeSchedule.Su = 0 THEN 0 ELSE 1 END AS Su
FROM #Temp
    INNER JOIN EmployeeSchedule on #Temp.ReportID = EmployeeSchedule.ReportID

返回基于匹配时间和天数的值
