我决定将日志记录添加到SQL Broker Queue的Activation存储过程 - 目标是记录错误。经过测试，日志表不断充满错误。
在添加记录之前：
添加记录后
服务器性能仍然只显示“blip”，但是......
服务队列“OutboundEventRequestQueue”目前已被禁用。
在运行以下命令
之前，日志记录不会停止ALTER DATABASE [MyDatabaseName] SET NEW_BROKER with ROLLBACK IMMEDIATE
存储程序：
ALTER PROCEDURE [dbo].[usp_OutboundEventRequestQueueActivation]
AS
BEGIN
SET NOCOUNT ON;
DECLARE @ConversationHandle UNIQUEIDENTIFIER;
DECLARE @MessageBody XML;
DECLARE @MessageTypeName SYSNAME;
---------------
-- READS ALL THE MESSAGES IN THE QUEUE
---------------
WHILE (1=1)
BEGIN
BEGIN TRY
BEGIN TRANSACTION;
---------------
-- KEEPS READING While In 'Notified' State

WAITFOR

RECEIVE TOP (1)
@ConversationHandle = conversation_handle,
@MessageBody = CAST(message_body AS XML),
@MessageTypeName = message_type_name
FROM [dbo].[OutboundEventRequestQueue]
), TIMEOUT 5000;
IF (@@ROWCOUNT = 0)
BEGIN
ROLLBACK TRANSACTION;
BREAK;
END

THE QUEUE：
ALTER QUEUE [dbo].[OutboundEventRequestQueue] WITH STATUS = OFF , RETENTION = OFF , ACTIVATION ( STATUS = ON , PROCEDURE_NAME = [dbo].[usp_OutboundEventRequestQueueActivation] , MAX_QUEUE_READERS = 10 , EXECUTE AS OWNER ), POISON_MESSAGE_HANDLING (STATUS = ON)
答案 0 :(得分：0)
好的，我现在觉得很蠢。我很惊讶没有人抓住这个...我很惊讶我没有。
问题代码：
WHILE（1 = 1）
经过纠正的存储程序：
这将正确捕获错误
