我想要一个sql查询,它可以计算出星期一,星期二等特定月份的次数。谁能告诉我怎么做?

(适用编辑)

鉴于MySQL date functions以及一些更简单的问题(how many days in monthfind month days),我已经找到了这个表达式:

ceil((day(last_day($dateInMonth)) - (7 + dayofweek(last_day($dateInMonth)) - $weekday) % 7) / 7)

其中$ dateInMonth是请求月份中的日期(例如今天为'2012-09-05'),$ weekday是SQL中的工作日数字(星期日为1,星期六为7)。

例如:本月(2012年9月)有4个星期五,但有5个星期六:

select ceil((day(last_day('2012-09-05')) - (7 + dayofweek(last_day('2012-09-05')) - 6) % 7) / 7);
select ceil((day(last_day('2012-09-05')) - (7 + dayofweek(last_day('2012-09-05')) - 7) % 7) / 7);

其他可能性:

  • 调用一些外部代码(例如Java,如果DBMS允许)
  • 使用预先计算的数据创建表格(例如DAYSPERMONTH)(如果月份可能在合理范围内)

检查sql method。找到一个月的具体天数。

此功能可以永久使用,有多种用途。

您所要做的就是创建函数并运行正确的select语句。我在函数末尾提供了一个示例(取自this site)。

只需用数据库名称替换顶部和底部的单词*database*

use *database*    
      SET ANSI_NULLS OFF
        GO

        SET QUOTED_IDENTIFIER ON
        GO


        create function [dbo].[F_TABLE_DATE]
        (
            @FIRST_DATE     datetime,
            @LAST_DATE      datetime
        )
        /*
        Function: dbo.F_TABLE_DATE

        This function returns a date table containing all dates
        from @FIRST_DATE through @LAST_DATE inclusive.
        @FIRST_DATE must be less than or equal to @LAST_DATE.
        The valid date range is 1754-01-01 through 9997-12-31.
        If any input parameters are invalid, the function will produce
        an error.

        The table returned by F_TABLE_DATE contains a date and
        columns with many calculated attributes of that date.
        It is designed to make it convenient to get various commonly
        needed date attributes without having to program and test
        the same logic in many applications.

        F_TABLE_DATE is primarily intended to load a permanant
        date table, but it can be used directly by an application
        when the date range needed falls outside the range loaded
        in a permanant table.

        If F_TABLE_DATE is used to load a permanant table, the create
        table code can be copied from this function.  For a permanent
        date table, most columns should be indexed to produce the
        best application performance.
