SQL 用于数据透视查询的 Server 2008 动态标题（每周）
SQL Server 2008 Dynamic Heading (Weekly) for Pivot Query
我想创建一个动态 header 来显示开始日期和结束日期之间的周数。我已经添加了周数和年份。现在我想要那些周和年之间的 DATENAME，我需要修复这个错误。
这是我目前所做的：
DECLARE @Query AS VARCHAR(MAX)
DECLARE @Weeks INT
DECLARE @DayNum INT
DECLARE @tmp TABLE(WeekNum VARCHAR(MAX))
DECLARE @Headers VARCHAR(MAX)
DECLARE @DayNumbers INT = 1
DECLARE @FromDate DATETIME
DECLARE @ToDate DATETIME
SET @FromDate = '01/01/2016'
SET @ToDate = '03/01/2016'
SET @DayNum = 1
DECLARE @Years INT = YEAR(@FromDate)
DECLARE @DateRange INT = DATEDIFF(Week,@FromDate,'12/31/'+CAST(YEAR(@FromDate) AS VARCHAR))
SET @Weeks = DATEDIFF(Week, @FromDate, @ToDate)
WHILE 1 = 1
BEGIN
INSERT INTO @tmp(WeekNum)
VALUES ('Week ' + CAST(@DayNumbers AS VARCHAR(MAX)) + ' - ' + CAST(@Years AS VARCHAR))
IF @DayNum <= @Weeks
BEGIN
SET @DayNum = @DayNum + 1
SET @DayNumbers = @DayNumbers + 1
IF @DateRange = @DayNumbers
BEGIN
SET @Years = @Years + 1
SET @DateRange = DATEDIFF(WEEK,'01/01/' + CAST(@Years AS VARCHAR),'12/31/' + CAST(@Years AS VARCHAR))
SET @DayNumbers = 1
END
END
ELSE
BREAK
END
SELECT @Headers = ISNULL(@Headers + ',','') + QUOTENAME(t.WeekNum)
FROM @tmp t
SELECT *
FROm @tmp
这是 2016 年 1 月 1 日 和 2016 年 3 月 1 日
之间几周的结果
让我们试试不同的日期2016 年 1 月 1 日和2016 年 12 月 31 日
这是另一个问题。
它一直上升到 2017 年，尽管它只到 2016 年 12 月
