Arguments

[ @schedule_name = ] 'schedule_name'

The name of the schedule. @schedule_name is sysname, with no default.

[ @enabled = ] enabled

Indicates the current status of the schedule. @enabled is tinyint, with a default of 1 (enabled). If 0, the schedule isn't enabled. When the schedule isn't enabled, no jobs run on this schedule.

[ @freq_type = ] freq_type

A value indicating when a job is to be executed. @freq_type is int, with a default of 0, and can be one of these values.

Value Description
1 Once
4 Daily
8 Weekly
16 Monthly
32 Monthly, relative to @freq_interval
64 Run when SQL Server Agent service starts
128 Run when the computer is idle (not supported in Azure SQL Managed Instance)

[ @freq_interval = ] @freq_interval

The days that a job is executed. @freq_interval is int, with a default of 1, and depends on the value of @freq_type.

Value of @freq_type Effect on @freq_interval
1 (once) @freq_interval is unused.
4 (daily) Every @freq_interval days.
8 (weekly) @freq_interval is one or more of the following (combined with an OR logical operator):

1 = Sunday
2 = Monday
4 = Tuesday
8 = Wednesday
16 = Thursday
32 = Friday
64 = Saturday
16 (monthly) On the @freq_interval day of the month.
32 (monthly relative) @freq_interval is one of the following:

1 = Sunday
2 = Monday
3 = Tuesday
4 = Wednesday
5 = Thursday
6 = Friday
7 = Saturday
8 = Day
9 = Weekday
10 = Weekend day
64 (when SQLServerAgent service starts) @freq_interval is unused.
128 @freq_interval is unused.

[ @freq_subday_type = ] freq_subday_type

Specifies the units for @freq_subday_interval. @freq_subday_type is int, with a default of 0, and can be one of these values.

Value Description (unit)
1 At the specified time
2 Seconds
4 Minutes
8 Hours

[ @freq_subday_interval = ] freq_subday_interval

The number of @freq_subday_type periods to occur between each execution of a job. @freq_subday_interval is int, with a default of 0. The interval must be at least 10 seconds long. @freq_subday_interval is ignored in those cases where @freq_subday_type is equal to 1.

[ @freq_relative_interval = ] freq_relative_interval

A job's occurrence of @freq_interval in each month, if @freq_interval is 32 (monthly relative). @freq_relative_interval is int, with a default of 0, and can be one of these values. @freq_relative_interval is ignored in those cases where @freq_type isn't equal to 32.

Value Description (unit)
1 First
2 Second
4 Third
8 Fourth
16 Last

[ @freq_recurrence_factor = ] freq_recurrence_factor

The number of weeks or months between the scheduled execution of a job. @freq_recurrence_factor is used only if @freq_type is 8, 16, or 32. @freq_recurrence_factor is int, with a default of 0.

[ @active_start_date = ] active_start_date

The date on which execution of a job can begin. @active_start_date is int, with a default of NULL, which indicates today's date. The date is formatted as yyyyMMdd. If @active_start_date isn't NULL, the date must be greater than or equal to 19900101.

After the schedule is created, review the start date and confirm that it's the correct date. For more information, see the section "Scheduling Start Date" in Create and Attach Schedules to Jobs.

For weekly or monthly schedules, the Agent ignores if @active_start_date is in the past, and instead uses the current date. When a SQL Server Agent schedule is created using sp_add_schedule there's an option to specify the parameter @active_start_date that is the date that job execution begins. If the schedule type is weekly or monthly, and the @active_start_date parameter is set to a date in the past, the @active_start_date parameter is ignored and the current date is used for @active_start_date.

[ @active_end_date = ] active_end_date

The date on which execution of a job can stop. @active_end_date is int, with a default of 99991231, which indicates December 31, 9999. Formatted as yyyyMMdd.

[ @active_start_time = ] active_start_time

The time on any day between @active_start_date and @active_end_date to begin execution of a job. @active_start_time is int, with a default of 000000, which indicates 12:00:00 A.M. on a 24-hour clock, and must be entered using the form HHmmss.

[ @active_end_time = ] active_end_time

The time on any day between @active_start_date and @active_end_date to end execution of a job. @active_end_time is int, with a default of 235959, which indicates 11:59:59 P.M. on a 24-hour clock, and must be entered using the form HHmmss.

[ @owner_login_name = ] 'owner_login_name'

The name of the server principal that owns the schedule. @owner_login_name is sysname, with a default of NULL, which indicates that the schedule is owned by the creator.

[ @schedule_uid = ] schedule_uid OUTPUT

A unique identifier for the schedule. @schedule_uid is a variable of type uniqueidentifier.

[ @schedule_id = ] schedule_id OUTPUT

An identifier for the schedule. @schedule_id is a variable of type int.

[ @originating_server = ] server_name

Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

SQL Server Management Studio provides an easy, graphical way to manage jobs, and is the recommended way to create and manage the job infrastructure.

Permissions

You can grant EXECUTE permissions on this procedure, but these permissions might be overridden during a SQL Server upgrade.

Other users must be granted one of the following SQL Server Agent fixed database roles in the msdb database:

  • SQLAgentUserRole
  • SQLAgentReaderRole
  • SQLAgentOperatorRole

For details about the permissions of these roles, see SQL Server Agent Fixed Database Roles.

Examples

A. Create a schedule

The following example creates a schedule named RunOnce. The schedule runs one time, at 23:30 on the day that the schedule is created.

USE msdb;
GO

EXEC dbo.sp_add_schedule
    @schedule_name = N'RunOnce',
    @freq_type = 1,
    @active_start_time = 233000;
GO

B. Create a schedule, attaching the schedule to multiple jobs

The following example creates a schedule named NightlyJobs. Jobs that use this schedule execute every day when the time on the server is 01:00. The example attaches the schedule to the job BackupDatabase and the job RunReports.

Note

This example assumes that the job BackupDatabase and the job RunReports already exist.

USE msdb;
GO

EXEC sp_add_schedule
    @schedule_name = N'NightlyJobs',
    @freq_type = 4,
    @freq_interval = 1,
    @active_start_time = 010000;
GO

EXEC sp_attach_schedule
    @job_name = N'BackupDatabase',
    @schedule_name = N'NightlyJobs';
GO

EXEC sp_attach_schedule
    @job_name = N'RunReports',
    @schedule_name = N'NightlyJobs';
GO
