Question

所以我有一个网页，要求用户将时间表输入到完整的每月数据中，但是我要做的是自动将时间表输入到该日期有公众假期的时间表中。帮助。

P.s我有一个表，其中存储了假日，因此我需要匹配今天的日期，如果在那一天是假日，则该框应显示'HH'sql。这是大型sql存储过程的一部分。但是我相信实现会在这里发生。...

DECLARE @DaysInMonth INT

    SELECT @DaysInMonth = DATEPART(dd, DATEADD(dd, -1, DATEADD(mm, 1, CAST(CAST(@Year AS VARCHAR) + '-' + CAST(@Month AS VARCHAR) + '-01' AS DATETIME))))

    DECLARE @Today DATETIME
    DECLARE @LunchStart DATETIME
    DECLARE @LunchEnd DATETIME
    DECLARE @CurrentMonth VARCHAR(16)
    DECLARE @CurrentDay INT
    SELECT @CurrentDay = 1

    SELECT @CurrentMonth = CAST(@Year AS VARCHAR) + '-' + CAST(@Month AS VARCHAR) + '-'

    DECLARE @DailyDataId INT

    WHILE @CurrentDay <= @DaysInMonth
    BEGIN
        SELECT @Today = CONVERT(DATETIME, @CurrentMonth + CAST(@CurrentDay AS VARCHAR),  20)

        -- If it's not a working day don't set a lunchbreak
        IF (DATENAME(weekday, @Today) IN (SELECT WorkingDay FROM dbo.udfGetWorkingDays(@TempTimesheetId)))
        BEGIN
            SELECT @LunchStart = @CurrentMonth + CAST(@CurrentDay AS VARCHAR) + ' ' + CAST(DATEPART(hh, @AMOut) AS VARCHAR) + ':' + CAST(DATEPART(mi, @AMOut) AS VARCHAR)
            SELECT @LunchEnd = @CurrentMonth + CAST(@CurrentDay AS VARCHAR) + ' ' + CAST(DATEPART(hh, @PMIn) AS VARCHAR) + ':' + CAST(DATEPART(mi, @PMIn) AS VARCHAR)
        END
        ELSE
        BEGIN
            SELECT @LunchStart = NULL
            SELECT @LunchEnd = NULL
        END

Answer 1

您可以使用EXISTS来检查一天是否为假期，即假期表中存在该天的记录。

IF EXISTS (SELECT *
                  FROM <holiday table>
                  WHERE <day column> = @Today)
BEGIN
  -- special handling for holidays goes here
END;

将<holiday table>替换为假期表的名称，并将<day column>替换为该表中保存日期的列。
