USE TestDB
declare @conversation uniqueidentifier
while exists (select 1 from sys.transmission_queue )
begin
set @conversation = (select top 1 conversation_handle from sys.transmission_queue )
end conversation @conversation with cleanup
end
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 ;
