How to create a scheduled job in SQL server 2008 via T-SQL?

问题

I want to create a job which deletes records from a database after a period of time has passed. For example I have a field in news table Time Stamp and each month a SQL query runs like a scheduled job against my database and deletes news where the time stamp is two month old. Generally I want to delete news for 2 month ago and older to not let my table become a large table. How can I accomplish this?

you should create a job in SQL below is a sample T-SQL for create a job via SQL agent

USE msdb ;
GO
EXEC dbo.sp_add_job
    @job_name = N'Weekly Sales Data Backup' ;
GO
EXEC sp_add_jobstep
    @job_name = N'Weekly Sales Data Backup',
    @step_name = N'Set database to read only',
    @subsystem = N'TSQL',
    @command = N'ALTER DATABASE SALES SET READ_ONLY', 
    @retry_attempts = 5,
    @retry_interval = 5 ;
GO
EXEC dbo.sp_add_schedule
    @schedule_name = N'RunOnce',
    @freq_type = 1,
    @active_start_time = 233000 ;
USE msdb ;
GO
EXEC sp_attach_schedule
   @job_name = N'Weekly Sales Data Backup',
   @schedule_name = N'RunOnce';
GO
EXEC dbo.sp_add_jobserver
    @job_name = N'Weekly Sales Data Backup';
GO

You will need to create a SQL Agent Job to schedule a job to periodically run. If you want to create the job with T-SQL, refer to How to: Create a SQL Server Agent Job (Transact-SQL).
