存储过程规范写法

--1.判断存储过程是否存在，存在则删除
IF OBJECT_ID('存储过程名称', 'P') IS NOT NULL
    DROP PROCEDURE dbo.usp_GetMeasureAnalysisIssueReminder_Query（存储过程名）
GO

--2.这些是 SQL-92 设置语句，使 SQL Server 2000/2005 遵从 SQL-92 规则。可不写

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

--3.创建存储过程并声明传入参数
CREATE PROCEDURE usp_GetMeasureAnalysisIssueReminder_Query(
     @companyCode NVARCHAR(30)
    )
AS

--4.编写存储过程内容

BEGIN

    declare @lastMonth varchar(20)
    declare @currentMonth varchar(20)

    set @lastMonth=(select CONVERT(varchar(7), dateadd(mm,-1,getdate()) , 120) + '-1')
    set @currentMonth=(select CONVERT(varchar(7), getdate() , 120) + '-1')

    ;with 
    cr as
    (
       select distinct PassNo from MS_AssetGroupMeasure agm
       inner join MS_MeasureAnalysis ma on agm.Id = ma.AssetGroupMeasureId
       where ma.MeasureResult='Fail' and agm.PassDate between @lastMonth and @currentMonth 
       AND agm.CompanyCode = @companyCode
    )

    select 
     ag.Name
    ,agm.PassNo
    ,agm.BatchNo
    ,ma.SampleName
    ,ma.Item
    ,ma.AddedDate
    ,mr.CodeDescription AS MeasureResult
    ,CONVERT(varchar(20),CONVERT(DECIMAL(13,3),ma.RandR)) AS RandR
    ,CONVERT(varchar(20),CONVERT(DECIMAL(13,3),ma.Ndc)) AS Ndc
   from MS_AssetGroupMeasure agm
   inner join AMG_AssetGroup ag on ag.Id = agm.AssetGroupId and ag.IsDeleted=0
   inner join MS_MeasureAnalysis ma on agm.Id=ma.AssetGroupMeasureId and ma.IsDeleted=0
   LEFT JOIN dbo.SYS_CodeTable mr ON ma.MeasureResult=mr.Code AND mr.IsDeleted=0  AND mr.CodeCategory = 'MeasureResult' 
   where agm.IsDeleted=0 and agm.PassNo in (select * from cr)
   order by agm.PassNo DESC,ma.AddedDate DESC
