在Sql中使用Try Catch

原文:在Sql中使用Try Catch

今天在写sql中出现了！我想在sql使用trycatch吧! 哎..但是语法又记不住了! 那就清楚我们的google大师吧! 嘿，网上关于在sql中使用Try Catch的还有真不少的文章! 闲话就少了! 今天记录下来以便下次使时查阅！

创建错误日志表:

CREATE TABLE ErrorLog(errNum INT,ErrSev NVARCHAR(1000),ErrState INT,ErrProc NVARCHAR(1000),ErrLine INT, ErrMsg NVARCHAR(2000))

创建错误日志记录存储过程:

CREATE PROCEDURE ErrorLog
AS
     SELECT ERROR_NUMBER() AS ErrNum,ERROR_SEVERITY()AS ErrSev,ERROR_STATE() AS ErrState,ERROR_PROCEDURE() AS ErrProc,ERROR_LINE()AS ErrLine,ERROR_MESSAGE()AS ErrMsg
     INSERT
     INTO ErrorLog
     VALUES(ERROR_NUMBER(),ERROR_SEVERITY(),ERROR_STATE(),ERROR_PROCEDURE(),ERROR_LINE(),ERROR_MESSAGE())
GO

写一个存储过程吧!里面使用一下Try Catch:

USE [Your_Test]
GO
/****** Object:  StoredProcedure [dbo].[getTodayBirthday]
        Script Date: 05/17/2010 15:38:46
        Author:jinho
        Desc:获?取?当?天?生?日?的?所?有?人?
        ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[getTodayBirthday]
AS
BEGIN TRY
 declare @today datetime;
 SET @today = GETDATE();--获?取?今?天?的?日?期?
 DECLARE @day VARCHAR(2);
 SET @day =REPLACE(DAY(@today),0,‘‘);
 DECLARE @month VARCHAR(2) ;
 SET @month = REPLACE(month(@today),0,‘‘);
 DECLARE @year VARCHAR(4);
 SET @year = YEAR(@today);
 SELECT * FROM dbo.UserInfo  WHERE REPLACE(DAY(CONVERT(DATETIME,Birthday )),0,’’) =@day AND REPLACE(MONTH(CONVERT(DATETIME,Brithday)),0,’’)=@month AND Birthday IS NOT NULL 

 END TRY
 BEGIN CATCH
 ErrorLog --调用上面的存储过程,保存错误日志
 END CATCH 

 说明:ERROR_NUMBER(),ERROR_SEVERITY(),ERROR_STATE(),ERROR_PROCEDURE(),ERROR_LINE(),ERROR_MESSAGE() 这几个函数只能用在Catch里面!

// ‘;
document.write(str);
document.write("");
}
// ]]>
