如何在 SQL Server 2005 中获取日期作为标题

Question

I am trying to get dates as headers that change depending on the current date. Here is an example of what I am trying to do in SQL Server 2005.
select c.[ar cust edi sef type], SUM(case when
s.[ar sale date] like DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))-7 and s.[ar sale document type] like 'invoice' then s.[AR SALE Balance Due] else 0 end) as getdate(),

getdate() does not work. Is there a way I can return a date as the header?

Answer 1

Column headers can not be dynamic. You can see this from the fact that usually you don't specify them as string, but like an identifier.

SELECT 1 as TestColumn

instead of

SELECT 1 as 'TestColumn'

You could do what you want in the form of a query you execute through exec

exec('SELECT 1 AS ' + CONVERT(nvarchar, getdate()))

Answer 2

Is this what you mean for date header?

You can do this without pivot, but mostly mssql uses pivot.

Answer 3

This code will list the dates as column headers. Used dynamic PIVOT to obtained the result. First I create a table with dates and a random text to test the solution. Substitute your table and change the code accordingly.

If you can provide your schema and data the answer will be more applicable and practical.

DECLARE @StartDate DATE = '20110901'
, @EndDate DATE = '20111001'

SELECT  DATEADD(DAY, nbr - 1, @StartDate) AS [Date]
,'test' AS  [Value]
into #temp_Dates
FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY c.object_id ) AS Nbr
      FROM      sys.columns c
    ) nbrs
WHERE   nbr - 1 <= DATEDIFF(DAY, @StartDate, @EndDate)
-------------------------------------------------------------------------------------- 


-----------Dynamic PIVOT section to make the date as a column header------------------

DECLARE @SQL  AS VARCHAR(MAX)
, @cols_ AS  vARCHAR(MAX) 
, @Table_Name VARCHAR(20)
SET @Table_Name = '#temp_Dates' 

--Making the column list dynamically 
 SELECT @cols_   = STUFF((SELECT DISTINCT ', '+QUOTENAME(  [T2].[Date]) 
               FROM  #temp_Dates [T2]              
               FOR XML PATH('')), 1, 1, '')          

SET @SQL = ' SELECT
       pivoted.* 
     
      FROM 
      (

      SELECT * 
      
      FROM  '+@Table_Name+'
     
      ) AS [p]
      PIVOT
      (
         MIN([P].[Value]) 
         FOR  [P].[Date]  IN (' + @cols_ + ')         
      ) AS pivoted;        

   ';

  PRINT( @SQL)
  EXEC (@SQL)


  DROP TABLE #temp_Dates

RESULT:
