step 1：perpar database data 复制代码 代码如下: use master go Create database Inventory go use Inventory go Create table inventory ( TitleId nvarchar(6) not null, Quantity int not null, primary key (TitleId,Quantity) ); go insert i
step 1：perpar database & data复制代码 代码如下:use mastergoCreate database Inventorygouse InventorygoCreate table inventory( TitleId nvarchar(6) not null, Quantity int not null, primary key (TitleId,Quantity));go
insert inventory values ('pc1001',100);insert inventory values ('pc1002',200);insert inventory values ('pc1003',300);insert inventory values ('pc1004',400);step 2: 创建整个SSB的基础框架.
首先创建信息类型复制代码 代码如下:Create Message Type [//mark/v10/types/inventory]Create Message Type [//mark/v10/types/inventoryresponse] 创建合约 复制代码 代码如下:Create contracts [//mark/v10/contracts/inventorycontract]( [//mark/v10/types/inventory] send by initiator, [//mark/v10/types/inventoryresponse] send by target ); 创建队列与服务复制代码 代码如下:create queue [inventory client queue];create service [//mark/v10/services/inventory client] on queue [inventory client queue] go --create inventory service create queue [inventory queue]; create service [//mark/v10/services/inventory] on queue [inventory queue] ( [//mark/v10/contracts/inventorycontract] );step 3：发送消息到消息队列中复制代码 代码如下:use Inventorygo--send messagebegin transaction declare @dialog_id uniqueidentifier begin dialog conversation @dialog_id from service [//mark/v10/services/inventory client] to service '//mark/v10/services/inventory' on contract [//mark/v10/contracts/inventorycontract] with encryption = off; send on conversation @dialog_id message type [//mark/v10/types/inventory] ( '<InventoryUpdate> <TitleId>pc1001</TitleId> <Quantity>102</Quantity> </InventoryUpdate>' ); commit transaction;发送成功后，可以查询 inventory_queue复制代码 代码如下:select conversation_handle, cast(message_body as xml) as conversation_body from [Inventory queue] 这里只是查询了两列。
其中conversation_body 就是 我们发出的信息了。
setp 4: 从 inventory queue 中获取信息并更新数据
复制代码 代码如下:use inventorygobegin transaction declare @dialog_id uniqueidentifier declare @message_body xml declare @amount int; declare @title nvarchar(128); receive @dialog_id = conversation_handle, @message_body = message_body from [dbo].[Inventory queue] print 'handle is' + cast(@dialog_id as nvarchar(90)) print 'message body is' + cast(@message_body as nvarchar(max) ) if(@dialog_id is not null) begin set @amount = @message_body.value('(/InventoryUpdate/Quantity)[1]','int'); set @title = @message_body.value('(/InventoryUpdate/TitleId)[1]','nvarchar(100)'); print 'a:'+cast(@amount as nvarchar(100)) print 'b:'+@title; Update inventory set Quantity = @amount where TitleId = @title; end end conversation @dialog_id; commit transaction;操作成功后再去查询inventory queue的表 犹豫里面的数据已经被receive 出来 就为空了。
数据同时被更新了
step 5: 接下来做个自动监听功能，只要有信息发送到队列，相关队列，就可以自动执行功能.
首先建立个存储过程，（把receive 中的那段代码拿过来就可以了）复制代码 代码如下:use Inventorygo--create procedure to receive message and update tablecreate proc InventoryProc as
begin transaction declare @dialog_id uniqueidentifier declare @message_body xml declare @amount int; declare @title nvarchar(128); waitfor( receive @dialog_id = conversation_handle, @message_body = message_body from [dbo].[Inventory queue]),timeout 5000; print 'handle is' + cast(@dialog_id as nvarchar(90)) print 'message body is' + cast(@message_body as nvarchar(max) ) if(@dialog_id is not null) begin set @amount = @message_body.value('(/InventoryUpdate/Quantity)[1]','int'); set @title = @message_body.value('(/InventoryUpdate/TitleId)[1]','nvarchar(100)'); print 'a:'+cast(@amount as nvarchar(100)) print 'b:'+@title; Update inventory set Quantity = @amount where TitleId = @title; end end conversation @dialog_id; commit transaction; go队列监听复制代码 代码如下:alter queue [inventory queue] with activation( status = on, procedure_name= InventoryProc, max_queue_readers=2, execute as self ); go完成后，只要发送队列信息后，就可以了
PS： 我们定义了 两个队列 还有个 inventory client queue
这个队列保存的是成功或者error 提示。用receive 方法也可以提取出来。复制代码 代码如下:select message_type_name from [Inventory client queue]
以上的 message type service 等信息 
如图所示，都在这里.
以上是SSB的入门实例，以后会再写一篇实际应用上的（以上的sql code 都是纯手工输入，可能还存在错误（虽然校验了两遍）,如果发生错误，对不起大家了。）
