【中文标题】在 SQL Server 中创建自定义日期范围列表以便于使用【英文标题】：Creating a list of custom Date Ranges for ease of use, in SQL Server 【发布时间】：2020-10-08 16:01:49 【问题描述】：给定一个日期（例如今天的日期，“2020 年 10 月 8 日”）和日期范围列表（昨天、明天、上周、下周、上个月、下个月等），我们如何到达在必要的日期范围内，通过 SQL。
Yesterday 2020-10-07 00:00:00.000 2020-10-07 23:59:59.000
Tomorrow 2020-10-09 00:00:00.000 2020-10-09 23:59:59.000
Last Week 2020-09-27 00:00:00.000 2020-10-03 23:59:59.000
Next Week 2020-10-11 00:00:00.000 2020-10-17 23:59:59.000
Last Month 2020-09-01 00:00:00.000 2020-09-30 23:59:59.000
Next Month 2020-11-01 00:00:00.000 2020-11-30 23:59:59.000
【问题讨论】：
日期函数是高度特定于供应商的。请用您正在运行的数据库标记您的问题：mysql、oracle、sqlserver...？ 明确标题，添加更具体的标签。 为什么你认为23:59:59 是一天的结束？这有可能在任何一个方向上咬你（丢失数据或四舍五入并包含太多数据）。尝试将范围视为“大于等于范围的开始，小于下一个范围的开始”。找到下个月的月初比找到本月的月底要容易得多。
另见 mssqltips.com/sqlservertip/6088/… 和 sqlblog.org/2011/10/19/… 和 sqlblog.org/2019/09/12/… 和 mssqltips.com/sqlservertip/6072/… ...虽然整个问答更像是一篇博文，而不是问答。
@AaronBertrand 这正是一篇博文。他们回答了自己的问题
【参考方案1】：
作为起点，我们有一个 Dates 表：
CREATE TABLE [dbo].[sysDate](
[DateKey] [int] NOT NULL,
[Date] [datetime] NOT NULL,
[Day] [char](10) NULL,
[DayOfWeek] [smallint] NULL,
[DayOfMonth] [smallint] NULL,
[DayOfYear] [smallint] NULL,
[PreviousDay] [datetime] NULL,
[NextDay] [datetime] NULL,
[WeekOfYear] [smallint] NULL,
[Month] [char](10) NULL,
[MonthOfYear] [smallint] NULL,
[QuarterOfYear] [smallint] NULL,
[Year] [int] NULL,
[FiscalYearString] [varchar](9) NULL,
[FiscalQuarter] [int] NULL,
[FiscalQuarterStartDate] [datetime] NULL,
[FiscalQuarterEndDate] [datetime] NULL,
[FiscalYear] [int] NULL,
[FiscalYearStartDate] [datetime] NULL,
[FiscalYearEndDate] [datetime] NULL
) ON [PRIMARY]
这是我们多年前创建的，其中填充了 1900 年至 2030 年的数据，它还具有识别会计期间的额外好处。大多数企业使用从 4 月 1 日开始的会计年度，但情况并非总是如此。
为了应对这一挑战，我们决定希望能够根据需要灵活地添加新范围，而无需额外自定义生成范围的存储过程。然后，我们需要一个表格来保存将日期转换为其范围的“recipie”。
CREATE TABLE [dbo].[CustomDateRanges](
[DateRangeID] [int] IDENTITY(1,1) NOT NULL,
[DateRangeLabel] [varchar](50) NOT NULL,
[DisplayOrder] [int] NULL,
[isPast] [bit] NULL,
[isPresent] [bit] NULL,
[isFuture] [bit] NULL,
[StartDateAdjuster] [varchar](5) NULL,
[StartDayOfWeekAdjuster] [varchar](5) NULL,
[StartDayOfMonthAdjuster] [varchar](5) NULL,
[StartDayOfYearAdjuster] [varchar](5) NULL,
[StartWeekOfYearAdjuster] [varchar](5) NULL,
[StartMonthOfYearAdjuster] [varchar](5) NULL,
[StartQuarterOfYearAdjuster] [varchar](5) NULL,
[StartYearAdjuster] [varchar](5) NULL,
[StartFiscalYearAdjuster] [varchar](5) NULL,
[StartFiscalQuarterAdjuster] [varchar](5) NULL,
[EndDateAdjuster] [varchar](5) NULL,
[EndDayOfWeekAdjuster] [varchar](5) NULL,
[EndDayOfMonthAdjuster] [varchar](5) NULL,
[EndDayOfYearAdjuster] [varchar](5) NULL,
[EndWeekOfYearAdjuster] [varchar](5) NULL,
[EndMonthOfYearAdjuster] [varchar](5) NULL,
[EndQuarterOfYearAdjuster] [varchar](5) NULL,
[EndYearAdjuster] [varchar](5) NULL,
[EndFiscalYearAdjuster] [varchar](5) NULL,
[EndFiscalQuarterAdjuster] [varchar](5) NULL
)
为了识别一个范围，我们现在声明需要进行哪些操作才能将给定日期取为其范围的开头，然后将同一日期取为其范围的结尾。 CustomDateRanges 表中的 NULL 列表示相关字段不需要任何操作。调整器列中的允许值为：
+<number> -- used to add <number> to the element
-<number> -- used to subtract <number> from the element
<number> -- used to explicitly set the element to <number>
'END' -- used to set the element to its last valid value, but only for "End" adjusters
我们将数据添加到CustomDateRanges
INSERT INTO CustomDateRanges(DateRangeLabel, DisplayOrder, isPast, isPresent, isFuture, StartDateAdjuster, StartDayOfWeekAdjuster, StartDayOfMonthAdjuster, StartDayOfYearAdjuster, StartWeekOfYearAdjuster, StartMonthOfYearAdjuster, StartQuarterOfYearAdjuster, StartYearAdjuster, StartFiscalYearAdjuster, StartFiscalQuarterAdjuster, EndDateAdjuster, EndDayOfWeekAdjuster, EndDayOfMonthAdjuster, EndDayOfYearAdjuster, EndWeekOfYearAdjuster, EndMonthOfYearAdjuster, EndQuarterOfYearAdjuster, EndYearAdjuster, EndFiscalYearAdjuster, EndFiscalQuarterAdjuster)
VALUES
-- DateRangeLabel StartDateAdjuster StartMonthOfYearAdjuster EndDateAdjuster EndMonthOfYearAdjuster
-- | |DisplayOrder| StartDayOfWeekAdjuster | StartQuarterOfYearAdjuster | EndDayOfWeekAdjuster | EndQuarterOfYearAdjuster
-- | | isPast | | StartDayOfMonthAdjuster | StartYearAdjuster | | EndDayOfMonthAdjuster| | EndYearAdjuster
-- | | | isPresent | | StartDayOfYearAdjuster | StartFiscalYearAdjuster | EndDayOfYearAdjuster | | EndFiscalYearAdjuster

然后是执行操作的代码。代码中的第一步是去掉时间组件（通过CAST(CAST(@Date AS Date) AS DateTime)，以确保对 sysDate 表的查找始终准确，代码中的最后一步是确保 StartDate 始终从午夜开始，并且EndDate 始终以23:59:59 结束，确保完整的日期范围。
