注释

SQL Server Agent jobs can be scheduled for execution by using SQL Server Agent. Scheduling jobs automates job execution when SQL Server Agent is enabled but jobs are not required to be scheduled. They can be executed on demand by a user with sufficient permissions. Jobs can have more than one active schedule, and SQL Server Agent evaluates all schedules to determine when to run the job.

With the JobSchedule object, you can:

• Create a schedule for a SQL Server Agent job.

• Remove a schedule from an existing SQL Server Agent job.

• Manage job schedules either by enabling a schedule or adjusting run times or frequencies.

The Name property of a JobSchedule object can contain up to 100 characters. The value of the Name property must be unique within a job.

To schedule a SQL Server Agent job for execution by SQL Server Agent

1. Create a JobSchedule object.

2. Set the Name property.

3. Get the Schedule object from the specified JobSchedule object.

4. Set the properties of the Schedule object.

5. Add the JobSchedule object to the JobSchedules collection of a Job object that references an existing SQL Server Agent job.
