Inserting the results set of SQL Dynamic Pivot Query into Temporary Table


How can I insert into global temporary table the results of the dynamic t-sql query in which columns is not fixed. See below for the table definition, value insertion and the t-sql for pivot query.

/****** Object:  Table [dbo].[ProdOrders]    Script Date: 30/8/2017 7:24:35 PM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[ProdOrders](
    [ItemCode] [nvarchar](50) NULL,
    [ReleasedDate] [date] NULL,
    [PlanQty] [float] NULL,
    [ActualQty] [float] NULL
) ON [PRIMARY]

GO

INSERT INTO [dbo].[ProdOrders]
           ([ItemCode]
           ,[ReleasedDate]
           ,[PlanQty]
           ,[ActualQty])

Declare @SQL varchar(max) = '

              ,B.*
         From  [dbo].[ProdOrders] A
         Cross Apply ( values ( convert(varchar(6),ReleasedDate,112)+''-Plan'',PlanQty)
                             ,( convert(varchar(6),ReleasedDate,112)+''-Actual'',ActualQty)
                     ) B (Item,Value)
      ) S
 Pivot (sum([Value]) For [Item] in (' + Stuff((Select Distinct ','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Plan') 
                                                              +','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Actual') 
                                               From [dbo].[ProdOrders]
                                               Order By 1 
                                               For XML Path('')),1,1,'')  + ') ) p'
Exec(@SQL);

I need to insert the results sets to global temporary table so that I can use it to refer with another query.


Solution

  • The script below creates dynamically a global temp table. This script does not have a check to see if the table allready exists, you have to add that yourself. Be carefull with using global temp tables. I think there are better alternatives to what you want.

        --Script for creating global temp table
        Declare @CreateTempTable [nvarchar](max) = '
        CREATE TABLE ##t ([ItemCode] nvarchar(50),' +
        stuff((Select distinct ',' + QuoteName(convert(varchar(6), ReleasedDate,112)+'-Plan') + ' float,' + QuoteName(convert(varchar(6),ReleasedDate,112)+'-Actual')  + '  float'
        From [dbo].[ProdOrders]
        Order By 1 For XML Path('')),1,1, '') + ')'
    
        Exec sp_executesql @CreateTempTable
    
        --Script for insert
        Declare @InsertSql [nvarchar](max) = '
        INSERT INTO ##t ([ItemCode], ' +
        stuff((Select distinct ','+QuoteName(convert(varchar(6), ReleasedDate,112)+'-Plan') + ', ' + QuoteName(convert(varchar(6),ReleasedDate,112)+'-Actual')  + ' '
        From [dbo].[ProdOrders]
        Order By 1 For XML Path('')),1,1, '') + ')'
    
        Declare @SQL varchar(max) = @InsertSql + '
        Select *
         From (
                Select A.ItemCode
                      ,B.*
                 From  [dbo].[ProdOrders] A
                 Cross Apply ( values ( convert(varchar(6),ReleasedDate,112)+''-Plan'',PlanQty)
                                     ,( convert(varchar(6),ReleasedDate,112)+''-Actual'',ActualQty)
                             ) B (Item,Value)
              ) S
         Pivot (sum([Value]) For [Item] in (' + Stuff((Select Distinct ','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Plan') 
                                                                      +','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Actual') 
                                                       From [dbo].[ProdOrders]
                                                       Order By 1 
                                                       For XML Path('')),1,1,'')  + ') ) p'
        Exec(@SQL);
    
        Select * From ##t
