将 SQL 动态数据透视查询的结果集插入临时 Table

Question

如何将列不固定的动态 t-sql 查询的结果插入到全局临时 table 中。请参阅下面的 table 定义、值插入和用于数据透视查询的 t-sql。

/****** 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]

 Pivot (sum([Value]) For [Item] in (' + Stuff((Select Distinct ','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Plan') 
                                                              +','+QuoteName(convert(varchar(6),ReleasedDate,112)+'-Actual')

                                               Order By 1 
                                               For XML Path('')),1,1,'')  + ') ) p'
Exec(@SQL);

我需要将结果集插入全局临时 table 以便我可以使用它来引用另一个查询。

Answer 1

在您的 select 语句中添加 into 子句并尝试

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

Answer 2

下面的脚本动态创建一个全局临时文件 table。这个脚本没有检查 table 是否已经存在，你必须自己添加。小心使用全局温度 tables。我认为有比您想要的更好的选择。

    --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
