sql-server – 存储过程事务

基本上我有一个应用程序的2个数据库.一个是存档 – 意味着不再被用户操纵的数据将被移动到这个数据库.但是,如果他们需要它,我将把所需的数据移回主数据库以供使用.我的存储过程如下：

CREATE PROCEDURE [dbo].[spReopenClosed] 
(
    @Return_Message VARCHAR(1024) = ''  OUT,@IID        uniqueidentifier,@OpenDate   smalldatetime,@ReopenedBy uniqueidentifier
)
AS
BEGIN
    SET NOCOUNT ON;

/******************************
*  Variable Declarations
*******************************/
    DECLARE     @ErrorCode  int  



/******************************
*  Initialize Variables
*******************************/

    SELECT @ErrorCode = @@ERROR

    IF @ErrorCode = 0

    BEGIN TRANSACTION
        /****************************************************************************
        * Step 1
        * Copy the Closed from the Archive
        ****************************************************************************/
        INSERT INTO OPS.dbo.SM_T_In
        SELECT          
        FROM OPS_ARCHIVE.Archive.SM_T_In    W
        WHERE W.GUID = @IID
            AND W.OpenDate = @OpenDate


        IF @ErrorCode <> 0
            BEGIN
                -- Rollback the Transaction
                ROLLBACK

                RAISERROR ('Error in Copying from the archive',16,1)
                RETURN
            END


        /****************************************************************************
        * Step 2
        * copy the notes
        ****************************************************************************/
        INSERT INTO OPS.dbo.SM_T_Notes
        SELECT 
        FROM OPS_ARCHIVE.Archive.SM_T_Notes W
        WHERE W.GUID = @IID

        IF @ErrorCode <> 0
            BEGIN
                -- Rollback the Transaction
                ROLLBACK

                RAISERROR ('Error in copying the notes',1)
                RETURN
            END

        /****************************************************************************
        * Step 3
        * Delete the from the Archive - this will also delete the notes
        ****************************************************************************/
        DELETE
        FROM OPS_ARCHIVE.Archive.SM_T_In
        WHERE OPS_ARCHIVE.Archive.SM_T_In.GUID = @IID

        IF @ErrorCode <> 0
            BEGIN
                -- Rollback the Transaction
                ROLLBACK

                RAISERROR ('Error in deleting the items from the Archive',1)
                RETURN
            END

        COMMIT

        BEGIN
            SELECT  @ErrorCode  = @@ERROR

            IF @ErrorCode = 0
                    SELECT  @Return_Message = 'All data was moved over'
        END



/*************************************
*  Get the Error Message for @@Error
*************************************/
    IF @ErrorCode <> 0
    BEGIN
        SELECT  @Return_Message = [Description]     -- Return the SQL Server error
          FROM  master.dbo.SYSMESSAGES
         WHERE  error = @ErrorCode
    END

/*************************************
*  Return from the Stored Procedure
*************************************/
    RETURN @ErrorCode                               -- =0 if success,<>0 if failure
END

我有两个插入,从存档数据库的2个表移动数据.如果这些插入成功,那么我将从存档数据库中删除数据.我非常感谢任何有关这方面的反馈意见,我需要确保我正确地做到这一点.

谢谢

此代码将在SQL 2005/2008中运行
