删除会话对象。

复制以下代码并将其粘贴到查询编辑器窗口中。然后，运行代码以删除用于支持该会话的对象。

IF EXISTS (SELECT * FROM sys.objects
           WHERE name =
           N'TargetActivProc')
     DROP PROCEDURE TargetActivProc;

IF EXISTS (SELECT * FROM sys.services
           WHERE name =
           N'//AWDB/InternalAct/TargetService')
     DROP SERVICE
     [//AWDB/InternalAct/TargetService];

IF EXISTS (SELECT * FROM sys.service_queues
           WHERE name = N'TargetQueueIntAct')
     DROP QUEUE TargetQueueIntAct;

-- Drop the intitator queue and service if they already exist.
IF EXISTS (SELECT * FROM sys.services
           WHERE name =
           N'//AWDB/InternalAct/InitiatorService')
     DROP SERVICE
     [//AWDB/InternalAct/InitiatorService];

IF EXISTS (SELECT * FROM sys.service_queues
           WHERE name = N'InitiatorQueueIntAct')
     DROP QUEUE InitiatorQueueIntAct;

-- Drop contract and message type if they already exist.
IF EXISTS (SELECT * FROM sys.service_contracts
           WHERE name =
           N'//AWDB/InternalAct/SampleContract')
     DROP CONTRACT
     [//AWDB/InternalAct/SampleContract];

IF EXISTS (SELECT * FROM sys.service_message_types
           WHERE name =
           N'//AWDB/InternalAct/RequestMessage')
     DROP MESSAGE TYPE
     [//AWDB/InternalAct/RequestMessage];

IF EXISTS (SELECT * FROM sys.service_message_types
           WHERE name =
           N'//AWDB/InternalAct/ReplyMessage')
     DROP MESSAGE TYPE
     [//AWDB/InternalAct/ReplyMessage];
