Question

这是我的存储过程

ALTER PROCEDURE dbo.sync_vmp

AS

    SET NOCOUNT ON;
    merge into FRM_DTA as Target
    using FRM_DTA_VMP as Source
    on Target.FRM_ID = Source.FRM_ID

如您所见，我正在将dbo.FRM_DTA_VMP中的数据合并到dbo.FRM_DTA

我的问题是如何在执行此存储过程后清空dbo.FRM_DTA_VMP？

如果合并中没有发生异常，我想这样做

如人们所说，你可以在MERGE语句后立即截断sproc中的表。检查@@ERROR变量的错误，如下所示; 澄清：

CREATE PROCEDURE YourProcedure
BEGIN
--code goes here

 IF @@ERROR = 0 --no errors
   BEGIN
    TRUNCATE TABLE dbo.FRM_DTA_VMP
   END
END
