清空SQL SERVER SEVICE BROKER 队列

USE [NDAS]
GO

/****** Object:  BrokerService [Service_Argot]    Script Date: 2012/8/30 15:07:06 ******/
CREATE SERVICE [Service_Argot]  ON QUEUE [dbo].[Queue_Argot] ([XMLMessageContract])
GO

那么客户端接受到的消息如果没有处理，也会积攒在客户端队列中，其实就相当于许多未读邮件，我们可以使用以下脚本读取队列 ，读取后队列自动清空: 

USE TestDB 
DECLARE @RecvReplyMsg NVARCHAR(100) ; 
DECLARE @RecvReplyDlgHandle UNIQUEIDENTIFIER ; 
BEGIN TRANSACTION ; 
WHILE ( 1 = 1 ) 
BEGIN 
WAITFOR 
( RECEIVE TOP(1) 
@RecvReplyDlgHandle = conversation_handle, 
@RecvReplyMsg = message_body 
FROM dbo.Test_TargetQueue 
), TIMEOUT 1000 ; 
END CONVERSATION @RecvReplyDlgHandle ; 
SELECT @RecvReplyMsg AS ReceivedReplyMsg ; 
END 
COMMIT TRANSACTION ;

SELECT state_desc,conversation_handle FROM sys.conversation_endpoints
