将SQL动态枢轴查询的结果集插入临时表中

Question

如何将动态t-sql查询的结果插入，其中列未固定。有关表定义，值插入和枢轴查询的T-SQL，请参见下文。

Exec(@SQL);

我需要将结果集插入全局临时表，以便我可以使用它与另一个查询一起引用。

Answer 1

下面的脚本会动态创建一个全局温度表。此脚本没有检查表是否已经准备就绪的表是否已经存在，您必须自己添加。使用全局临时表谨慎。我认为您想要的是更好的选择。

    --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

Answer 2

在您的选择语句中添加到子句中，然后尝试

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