判断你的数据库YourDatabaseName是否启用了Service Broker
SELECT is_broker_enabled FROM sys.databases WHERE name YourDatabaseName;
如果未启用可以通过以下命令启用。
ALTER DATABASE YourDatabaseName SET ENABLE_BROKER;
创建MessageContractQueue和Service
然后按照以下步骤分别创建MessageContractQueue和Service。
--1. 创建MessageContractQueue和Service
CREATE MESSAGE TYPE [DBTestSync] VALIDATION NONE;CREATE CONTRACT [DBTestmessages] ([DBTestSync] SENT BY ANY)CREATE QUEUE [dbo].[DBTestSyncQueue] WITH STATUS ON , RETENTION OFF , POISON_MESSAGE_HANDLING (STATUS ON) ;CREATE SERVICE [DBTestSyncService] ON QUEUE [dbo].[DBTestSyncQueue] ;创建调用存储过程
The dequeue stored procedure (Service Program) is core of service broker implementation. Processes the messages in the Queue Handles the known errors – Inserts back the message into the queue and reprocesses it. Send email notifications for unhandled exceptions. Inserts the unknown errors into the ServiceBrokerException table.
--2. 创建调用的存储过程
--DEQUEUE SP/ SERVICE PROGRAM - This code is responsible for picking the message from the queue and processing data
CREATE proc [dbo].[SP_TEST_SERVICE_BROKER_IN_SP]
as
beginset nocount on;DECLARE Handle UNIQUEIDENTIFIER ;DECLARE MessageType SYSNAME ;DECLARE Message XMLDECLARE dt DATEtime GETDATE()DECLARE ID INT DECLARE Name VARCHAR(50)declare spname varchar(500)declare ERROR VARCHAR(500)SET XACT_ABORT ONBEGIN TRY--BEGIN TRANWAITFOR( RECEIVE TOP (1) Handle conversation_handle,MessageType message_type_name,Message message_body FROM dbo.[DBTestSyncQueue]),TIMEOUT 1000--[DBTestSyncQueue]就是上面创建的Queue--SELECT cast(Message as xml)set spname CAST(CAST(Message.query(/mydata/SPName/text()) AS NVARCHAR(MAX)) AS VARCHAR(500))IF spnameSP_TEST_SERVICE_BROKERBEGINDeclare Id int,Name intSET Id convert(int, CAST(CAST(Message.query(/mydata/Id/text()) AS NVARCHAR(MAX)) AS VARCHAR(50)))SET Name convert(int, CAST(CAST(Message.query(/mydata/Name/text()) AS NVARCHAR(MAX)) AS VARCHAR(50)))update [Users] set NameName where IdIdEND--COMMIT TRANEND TRYBEGIN CATCH--ROLLBACKDECLARE ErrorHandle UNIQUEIDENTIFIER;SET ERROR ERROR_MESSAGE()IF (ERROR_NUMBER() 1205 OR ERROR_NUMBER() 1222 OR ERROR_NUMBER()18452)BEGINBEGIN DIALOG CONVERSATION ErrorHandleFROM SERVICE DBTestSyncService TO SERVICE DBTestSyncServiceON CONTRACT DBTestmessages WITH ENCRYPTION OFF;SEND ON CONVERSATION ErrorHandle MESSAGE TYPE DBTestSync(MESSAGE);ENDELSEBEGININSERT INTO dbo.ServiceBrokerExceptionVALUES (Message,ERROR ,dt);declare messagebody varchar(5000)concat(bError in processing Service Broker Queue/bBRbSPName:/b,isnull(spname,SP Cant be Determined),BR bERROR:/b,isnull(ERROR, Error cant be Determined)) exec msdb.dbo.sp_send_dbmail profile_nameDBAMail, recipients group-agency360alterdomusgroup.onmicrosoft.com,subjectService Broker: Error in processing Service Broker Queue,bodymessagebody, body_formatHTMLENDEND CATCH;SET XACT_ABORT OFF
ENDGO启用SQL Agent并创建Job执行存储过程 Job需要创建两个Steps,两个Steps内容都是exec SP_TEST_SERVICE_BROKER_IN_SP。 设置Job的Steps需要创建两个steps。 Step 1 1. 在General里面输入Step1-SP_TEST_SERVICE_BROKER_IN_SP 2. Database选择YourDatabaseName 3. Advanced选择Go to the next step Step 2 1. 在General里面输入Step2-SP_TEST_SERVICE_BROKER_IN_S 2. Database选择YourDatabaseName 3. Advanced选择Go to step: Step1-SP_TEST_SERVICE_BROKER_IN_SP 设置Job的Schedules:
Occurs every day every 10 second(s) between 12:00:00 AM and 11:59:59 PM. Schedule will be used starting on 11/14/2024. Name: ServiceBrokerJob--自己随意命名 Schedule type: Recurring Frequence Occurs: Daily Recurs every: 1 days(s) Daily frequence Occures every: 10 seconds--根据自己需要设置 Startint at: 12:00:00 AM Ending at: 11:59:59 PM Duration: Start date: 11/14/2024--默认是你创建的日期 调用demo
--3. 调用demo。你可以在你调用的地方这样子写
create proc SP_TEST
(Id int,Name nvarchar(25)
)
AS
BEGINSELECT * INTO #TmpTest --Forming a Message-- FROM ( SELECT Id AS Id ,Name AS Name ,SP_TEST_SERVICE_BROKER AS SPName )a DECLARE XMLMESSAGE XML; SELECT XMLMESSAGE (SELECT * FROM #TmpTest FOR XML PATH (mydata), TYPE); ----Sending Message to the Queue---- DECLARE Handle UNIQUEIDENTIFIER; BEGIN DIALOG CONVERSATION Handle FROM SERVICE DBTestSyncService TO SERVICE DBTestSyncService ON CONTRACT DBTestmessages WITH ENCRYPTION OFF; SEND ON CONVERSATION Handle MESSAGE TYPE DBTestSync(XMLMESSAGE);
END常见故障排除
如果Service Broker没有按照预期结果运行可以查看SQL Server Service Broker故障排除_sqlserver禁用servicebroker-CSDN博客
