SQL存储过程中使用BEGIN TRY捕捉错误并保存

1、创建保存错误的数据表:

CREATE TABLE ErrorLog(
                                            errNum INT,
                                            ErrSev NVARCHAR(500),
                                            ErrState INT,
                                            ErrProc NVARCHAR(1000),
                                            ErrLine INT, 
                                            ErrMsg NVARCHAR(2000)
                                            )

2、创建保存错误信息的存储过程：

CREATE PROCEDURE InsErrorLog
AS 
BEGIN
        INSERT INTO ErrorLog 
             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 
END

3、在存储过程中使用BEGIN TRY,并捕捉错误保存：

CREATE　PROCEDURE GetErrorTest
AS
BEGIN TRY
   
     ***
END TRY
BEGIN CATCH
    EXEC InsErrorLog --调用 InsErrorLog 存储过程,保存错误日志
END CATCH
