SQL Server日志记录失败的查询

Question

我试图实现一个系统范围内的日志记录，它将记录我们的dabatase中所有失败的存储过程执行，并且正在查看扩展事件。

我做了一些研究，它似乎很容易捕获失败使用下面的代码语句：

--Create an extended event session 
CREATE EVENT SESSION what_queries_are_failing ON SERVER 
ADD EVENT sqlserver.error_reported (
    ACTION (sqlserver.sql_text 
     , sqlserver.tsql_stack 
     , sqlserver.database_id 
     , sqlserver.username 
     ) 
    WHERE ([severity] > 10) 
    ) 
ADD TARGET package0.asynchronous_file_target (
    SET filename = 'C:\XEventSessions\what_queries_are_failing.xel' 
    , metadatafile = 'C:\XEventSessions\what_queries_are_failing.xem' 
    , max_file_size = 5 
    , max_rollover_files = 5 
    ) 
    WITH (MAX_DISPATCH_LATENCY = 5 SECONDS) 
GO 

-- Start the session 
ALTER EVENT SESSION what_queries_are_failing ON SERVER STATE = START 
GO 

;WITH events_cte 
AS (
    SELECT DATEADD(mi, DATEDIFF(mi, GETUTCDATE(), CURRENT_TIMESTAMP), xevents.event_data.value('(event/@timestamp)[1]', 'datetime2')) AS [err_timestamp] 
     , xevents.event_data.value('(event/data[@name="severity"]/value)[1]', 'bigint') AS [err_severity] 
     , xevents.event_data.value('(event/data[@name="error_number"]/value)[1]', 'bigint') AS [err_number] 
     , xevents.event_data.value('(event/data[@name="message"]/value)[1]', 'nvarchar(512)') AS [err_message] 
     , xevents.event_data.value('(event/action[@name="sql_text"]/value)[1]', 'nvarchar(max)') AS [sql_text] 
     , xevents.event_data 
    FROM sys.fn_xe_file_target_read_file('S:\XEventSessions\what_queries_are_failing*.xel', 'S:\XEventSessions\what_queries_are_failing*.xem', NULL, NULL) 
    CROSS APPLY (
     SELECT CAST(event_data AS XML) AS event_data 
     ) AS xevents 
    ) 
SELECT * 
FROM events_cte 
ORDER BY err_timestamp; 

不过，我想立即失败语句存储到一个表，让我们把它Logs.Errors但我找不到办法做到这一点，上面的方法将不得不作为一个计划的工作。

眼下，我们的程序看起来像：

CREATE PROCEDURE [dbo].[MyProcedure] 
AS 
BEGIN 
    SET NOCOUNT ON; 
    BEGIN TRY 
     SELECT 1; 
    END TRY 
    BEGIN CATCH 
     EXECUTE Logs.PrintError; 
     EXECUTE Logs.LogError; 
    END CATCH 
END 

凡Logs.LogError过程使得DBCC INPUTBUFFER();使用，但它并没有捕捉到的参数，只是在执行的具体程序。这就是我可以从它那里得到：

+----------------------------+-----------+-----------+------------------------------+ 
|  ErrorMessage  | EventType | Parameter |   Statement   | 
+----------------------------+-----------+-----------+------------------------------+ 
| Incorrect syntax near '.'. | RPC Event |   0 | DbName.dbo.FailedProcedure;1 | 
+----------------------------+-----------+-----------+------------------------------+ 

我正在寻找一种方式，迫使它捕获整个陈述或XE插入记录直入一些表，如果可能的话要么使DBCC INPUTBUFFER()工作。

任何问题 - 让我知道。

我发现XEvents非常适合在事件发生时进行监视。但是，他们没有提供“处理”观察事件的机制。为了填补这个空白，我使用了Event Notifications。我经常将它们描述为异步DDL触发器。我会让你决定这个tl;dr的定义是否准确。

如果你想给事件通知一个尝试，这里是一个脚本，你可以开始（抱歉，它真的很长）。如果您有任何疑问/问题，请告知我。我会尽力尽可能地回复。
