如何在全局临时表中插入未修复列的动态t-sql查询的结果。 请参阅下面的表定义,值插入和用于数据透视查询的t-sql。

我需要将结果集插入到全局临时表中,以便我可以使用它来引用另一个查询。

在select语句中添加into子句并尝试

Declare @SQL varchar(max) = '
Select *
into ##globaltemptable
From ( ...

下面的脚本动态创建一个全局临时表。此脚本没有检查表是否已存在,您必须自己添加。 小心使用全局临时表。我认为你有更好的选择。

    --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
