【解决方案】 在数据库建立“删除查询用的临时表”的JOB，具体方法和语句见下面。 注：其功能就是清除这些临时表的，这个功能需要启动SQL Server Agent /* 在master库中执行 */ -- Script generated on 2006-2-27 14:07 -- By: PDOMAINhgs -- Server: NOCONA-DRPDRP861 BEGIN TRANSACTION DECLARE @JobID BINARY(16) DECLARE @ReturnCode INT SELECT @ReturnCode = 0 IF (SELECT COUNT(*) FROM msdb.dbo.syscategories WHERE name = N'[Uncategorized (Local)]') < 1 EXECUTE msdb.dbo.sp_add_category @name = N'[Uncategorized (Local)]' -- Delete the job with the same name (if it exists) SELECT @JobID = job_id FROM msdb.dbo.sysjobs WHERE (name = N'删除查询用的临时表') IF (@JobID IS NOT NULL) BEGIN -- Check if the job is a multi-server job IF (EXISTS (SELECT * FROM msdb.dbo.sysjobservers WHERE (job_id = @JobID) AND (server_id <> 0))) BEGIN -- There is, so abort the script RAISERROR (N'Unable to import job ''删除查询用的临时表'' since there is already a multi-server job with this name.', 16, 1) GOTO QuitWithRollback END ELSE -- Delete the [local] job EXECUTE msdb.dbo.sp_delete_job @job_name = N'删除查询用的临时表' SELECT @JobID = NULL END BEGIN -- Add the job EXECUTE @ReturnCode = msdb.dbo.sp_add_job @job_id = @JobID OUTPUT , @job_name = N'删除查询用的临时表', @owner_login_name = N'sample', @description = N'No description available.', @category_name = N'[Uncategorized (Local)]', @enabled = 1, @notify_level_email = 0, @notify_level_page = 0, @notify_level_netsend = 0, @notify_level_eventlog = 2, @delete_level= 0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback -- Add the job steps EXECUTE @ReturnCode = msdb.dbo.sp_add_jobstep @job_id = @JobID, @step_id = 1, @step_name = N's1', @command = N'declare @tbname varchar(100) declare @sSQL varchar(8000) Set @sSQL = '''' declare cur cursor for select name from sysobjects where OBJECTPROPERTY(id, N''IsUserTable'') = 1 and name like ''tmp_%'' and crdate<=dateadd(hh,-2,getdate()) order by crdate OPEN cur FETCH NEXT FROM cur INTO @tbname WHILE @@FETCH_STATUS = 0 BEGIN Set @sSQL = @sSQL + '' Drop Table '' + @tbName FETCH NEXT FROM cur INTO @tbname If len(@sSQL)>7000 Begin exec(@sSQL) Set @sSQL='''' End END CLOSE cur DEALLOCATE cur exec(@sSQL)', @database_name = N'U8DRP_TempQuery', @server = N'', @database_user_name = N'', @subsystem = N'TSQL', @cmdexec_success_code = 0, @flags = 0, @retry_attempts = 0, @retry_interval = 1, @output_file_name = N'', @on_success_step_id = 0, @on_success_action = 1, @on_fail_step_id = 0, @on_fail_action = 2 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXECUTE @ReturnCode = msdb.dbo.sp_update_job @job_id = @JobID, @start_step_id = 1 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback -- Add the job schedules EXECUTE @ReturnCode = msdb.dbo.sp_add_jobschedule @job_id = @JobID, @name = N's1', @enabled = 1, @freq_type = 4, @active_start_date = 20030529, @active_start_time = 0, @freq_interval = 1, @freq_subday_type = 1, @freq_subday_interval = 0, @freq_relative_interval = 0, @freq_recurrence_factor = 0, @active_end_date = 99991231, @active_end_time = 235959 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback -- Add the Target Servers EXECUTE @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @JobID, @server_name = N'(local)' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback END COMMIT TRANSACTION GOTO EndSave QuitWithRollback: IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION EndSave: |
