下面是一个使用临时表的存储过程例子

USE [JointFrame31_zw]
GO
/****** Object:  StoredProcedure [dbo].[Proc_ZL_GetMonthFlow]    Script Date: 2017/04/05 9:18:29 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

ALTER PROCEDURE [dbo].[Proc_ZL_GetMonthFlow]

    insert into #w
    exec [AutoMonitor].[dbo].Proc_Big_Get_Pollutant_Month_Data_Water

    truncate table #w
    drop table #w

    truncate table #g

    truncate table #date
