这是我的SP：

    Order By    COMP.Company_id


    /*
        We now need to create a table for the existing content for the old company.

    If Object_ID('tempdb..#Content') IS Not Null
        Begin

    Order By COMP.Company_id

    /*

    Insert  Into dbo.Content
    (
            Title,
            Content
    )   
    Select  Title,
            Content 
    From    dbo.#Content

    /*
        Have to the Content table up to the content sections table
        as this contains what ID has been add to the Content Table. 
    */


    Insert Into dbo.ContentSection
    (
            ContentID,
            SectionID,
            MenuOrder,
            CompanyID,
            SubMenu,
            Link,
            HeaderMenu,
            ParentContentID
    )

    Select  C.MaxContentID + C.ID,
            CS.SectionID,
            CS.MenuOrder,
            CS.NewCompanyID,
            CS.Submenu,
            CS.Link,
            CS.HEaderMEnu,
            CS.ParentContentID
    From    dbo.#Content C
    Join    dbo.#ContentSections CS
    On      C.ID = CS.ID

End

当我运行它时，我得到以下内容：

例如：

（41行（s）受影响）

消息207，级别16，状态3，过程sp_CopyCompanyContent，第122行列名称“ID”无效。消息207，级别16，状态3，过程sp_CopyCompanyContent，第122行列名称“ID”无效。消息207，级别16，状态3，过程sp_CopyCompanyContent，第122行列名称“ID”无效。

（1行受影响）

任何人都可以看到它为什么说无效的列ID？它应该完美地加入和填充内容。

尝试替换代码：

 Alter table #ContentSections Add ID Int Identity(1,1)
 Alter table #Content Add ID Int Identity(1,1)

与

exec('Alter table #ContentSections Add ID Int Identity(1,1)')
exec('Alter table #Content Add ID Int Identity(1,1)')

或添加到“select into”标识列，如下所示：

SELECT  ID=IDENTITY (int, 1, 1) ....
INTO    #Table
FROM    Table

例如：

 Select         ID=IDENTITY (int, 1, 1),
                CS.ContentID,
                CS.SectionID,
                CS.MenuOrder,
                @intNewCompanyID NewCompanyID,
                CS.CompanyID OldCompanyID,
                CS.SubMenu,
                CS.Link,
                CS.HeaderMenu,
                CS.ParentContentID,
                CRS.*

    Into        dbo.#ContentSections

    From        dbo.Company COMP
    Join        dbo.ContentSection CS
    On          COMP.Company_id = CS.CompanyID  
    Join        dbo.Content CONT
    On          CONT.ContentID = CS.ContentID

    Cross Join  (
                    Select  MAx(ContentSectionID) MaxContentSectionID
                    From    dbo.ContentSection CONT
                ) crs

    Where       COMP.Company_id  = @intCopyFromCompanyID
    Order By    COMP.Company_id
