SQL Server 中使用 Try Catch 处理异常

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

CREATE PROCEDURE ProcErrorLog
AS 
BEGIN
     SELECT 
        ERROR_NUMBER() AS ErrNum,--返回导致运行 CATCH 块的错误消息的错误号。
        ERROR_SEVERITY()AS ErrSev,--返回导致 CATCH 块运行的错误消息的严重级别
        ERROR_STATE() AS ErrState,--返回导致 CATCH 块运行的错误消息的状态号
        ERROR_PROCEDURE() AS ErrProc,--返回出现错误的存储过程名称
        ERROR_LINE()AS ErrLine,--返回发生错误的行号
        ERROR_MESSAGE()AS ErrMsg--返回导致 CATCH 块运行的错误消息的完整文本 
     INSERT INTO ErrorLog VALUES(
        ERROR_NUMBER(),
        ERROR_SEVERITY(),
        ERROR_STATE(),
        ERROR_PROCEDURE(),
        ERROR_LINE(),
    ERROR_MESSAGE())
END

CREATE PROCEDURE TestErrorLog
AS
BEGIN
    BEGIN TRY 
        SELECT GETDATE() 
        SELECT 1/0--Evergreen divide by zero example! 
    END TRY 
    BEGIN CATCH 
        SELECT 'There was an error! ' + ERROR_MESSAGE() 
        ProcErrorLog --调用上面的存储过程,保存错误日志
        RETURN  
    END CATCH; 
END
