属性
名称 | 说明 | |
---|---|---|
ActiveEndDate | Gets or sets the date and time when the schedule ends. | |
ActiveEndTimeOfDay | Gets or sets the time when the job schedule stops for the day. | |
ActiveStartDate | Gets or sets the date and time when the schedule starts. | |
ActiveStartTimeOfDay | Gets or sets the time when the job schedule starts for the day. | |
DateCreated | Gets the date and time when the job schedule was created. | |
ExecuteForScalar | 获取或设置 Boolean 属性值,该值指定对象是否设置为针对标量选项执行。 (从 SqlSmoObject 继承。) | |
FrequencyInterval | Gets or sets the frequency interval, which determines how often the job is scheduled to run. | |
FrequencyRecurrenceFactor | Gets or sets the number of weeks or months between scheduled jobs for schedules with a weekly or monthly frequency type, respectively. | |
FrequencyRelativeIntervals | Gets or sets the ordinal value of a day relative to the first day of the month, such as first, second, or last. | |
FrequencySubDayInterval | Gets or sets the interval between scheduled jobs that run during the day. | |
FrequencySubDayTypes | Gets or sets the unit of time used to specify the interval between scheduled jobs that run during the day. | |
FrequencyTypes | Gets or sets the way in which frequency is evaluated for the job schedule, whether it's one time only, or weekly, or when the processor is idle, for example. | |
ID | 不要在您的代码中直接引用此成员。它支持 SQL Server 基础结构。 Gets the ID value that uniquely identifies the schedule. (从 ScheduleBase 继承。) | |
IsEnabled | Gets or sets the Boolean property value that specifies whether the job schedule is enabled or disabled. | |
IsTouched | 获取 Boolean 属性值,该值指定在服务器上对象属性是否已更新但尚未持久化。 (从 SqlSmoObject 继承。) | |
JobCount | Gets the number of jobs that require the referenced job schedule. | |
Name | Gets or sets the name of the object. (从 NamedSmoObject 继承。) | |
ObjectInSpace | 获取 Boolean 属性值,该值指定对象是否单独存在,或者对象是否直接或间接连接到 SQL Server 的实例。 (从 SqlSmoObject 继承。) | |
Parent | Gets or sets the Job object that is the parent of the JobSchedule object. | |
Properties | 获取表示对象属性的 Property 对象的集合。 (从 SqlSmoObject 继承。) | |
ScalarResult | 获取所引用对象的标量结果。 (从 SqlSmoObject 继承。) | |
ScheduleUid | Gets and sets the Guid for the schedule associated with the instance. | |
State | Gets the state of the referenced object. (从 SmoObjectBase 继承。) | |
Urn | 获取唯一标识对象的统一资源名称 (URN) 地址值。 (从 SqlSmoObject 继承。) | |

注释
SQL Server Agent jobs can be scheduled to run by using SQL Server Agent. Jobs can be scheduled to run when SQL Server Agent is enabled, but jobs are not required to be scheduled. They can be run on demand by a sufficiently privileged user. Jobs can have more than one active schedule. SQL Server Agent evaluates all schedules to determine when to run the job. By using the JobSchedule object, you can do the following:
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.
To get or set JobSchedule object properties, users must be a member of the SQLAgentUserRole database role on the MSDB database, or be the owner of the job, or be a member of the sysadmin fixed server role.
To create a job schedule, users must be a member of the SQLAgentUserRole database role on the MSDB database, or be a member of the sysadmin fixed server role.
To drop a job schedule, users must be a member of the SQLAgentUserRole database role on the MSDB database, or be a member of the sysadmin fixed server role.
