我目前在插入更新觸發器中調用存儲過程異步時出現問題。爲此我使用服務代理。SQL Server 2005 Asnyc存儲過程
--message type
CREATE MESSAGE TYPE [TheMessage] VALIDATION = NONE
--contract
CREATE CONTRACT [TheContract] ([TheMessage] SENT BY ANY);
--queue
CREATE QUEUE [TheQueue] WITH ACTIVATION
(STATUS = ON, MAX_QUEUE_READERS = 1,
PROCEDURE_NAME = TheStoreProcedure,
EXECUTE AS OWNER);
--service
CREATE SERVICE [TheService] ON QUEUE [TheQueue] ([TheContract]);
在觸發器:
DECLARE @Handle UNIQUEIDENTIFIER;
BEGIN DIALOG CONVERSATION @Handle
FROM SERVICE [TheService]
TO SERVICE 'TheService'
ON CONTRACT [TheContract]
WITH ENCRYPTION = OFF;
SEND ON CONVERSATION @Handle
MESSAGE TYPE [TheMessage](N'some data');
在存儲過程:
DECLARE @Handle UNIQUEIDENTIFIER;
DECLARE @MessageType SYSNAME;
RECEIVE TOP (1)
@Handle = conversation_handle,
@MessageType = message_type_name
FROM [TheQueue];
IF(@Handle IS NOT NULL)
BEGIN
-- some statements
END
此設置似乎並沒有工作。觸發器不會拋出任何錯誤,所以我假設消息已排隊。但存儲內的接收似乎不起作用。我的任何陳述都沒有被執行。
