Arguments

• [ @publication = ] 'publication'
  Is the name of the publication. publication is sysname, with no default.

• [ @dynamic_snapshot_jobname = ] 'dynamic_snapshot_jobname'
  Is the name of the snapshot job being changed. dynamic_snapshot_jobnameis sysname, with default value of N'%'. If dynamic_snapshot_jobid is specified, you must use the default value for dynamic_snapshot_jobname.

• [ @dynamic_snapshot_jobid = ] 'dynamic_snapshot_jobid'
  Is the ID of the snapshot job being changed. dynamic_snapshot_jobid is uniqueidentifier, with default value of NULL. If dynamic_snapshot_jobnameis specified, you must use the default value for dynamic_snapshot_jobid.

• [ @frequency_type = ] frequency_type
  Is the frequency with which to schedule the agent. frequency_type is int, and can be one of the following values.

  Value	Description
  1	One time
  2	On demand
  4	Daily
  8	Weekly
  16	Monthly
  32	Monthly relative
  64	Autostart
  128	Recurring
  NULL (default)

• [ @frequency_interval = ] frequency_interval
  The days that the agent runs. frequency_interval is int, and can be one of the following values.

  Value	Description
  1	Sunday
  2	Monday
  3	Tuesday
  4	Wednesday
  5	Thursday
  6	Friday
  7	Saturday

  Value	Description
  1	Once
  2	Second
  4	Minute
  8	Hour
  NULL (default)

• [ @frequency_subday_interval = ] frequency_subday_interval
  Is the interval for frequency_subday. frequency_subday_interval is int, with a default of NULL.

• [ @frequency_relative_interval = ] frequency_relative_interval
  Is the date that the Merge Agent runs. This parameter is used when frequency_type is set to 32 (monthly relative). frequency_relative_interval is int, and can be one of the following values.

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

• [ @frequency_recurrence_factor = ] frequency_recurrence_factor
  Is the recurrence factor used by frequency_type. frequency_recurrence_factor is int, with a default of NULL.

• [ @active_start_date = ] active_start_date
  Is the date when the Merge Agent is first scheduled, formatted as YYYYMMDD. active_start_date is int, with a default of NULL.

• [ @active_end_date = ] active_end_date
  Is the date when the Merge Agent stops being scheduled, formatted as YYYYMMDD. active_end_date is int, with a default of NULL.

• [ @active_start_time_of_day = ] active_start_time_of_day
  Is the time of day when the Merge Agent is first scheduled, formatted as HHMMSS. active_start_time_of_day is int, with a default of NULL.

• [ @active_end_time_of_day = ] active_end_time_of_day
  Is the time of day when the Merge Agent stops being scheduled, formatted as HHMMSS. active_end_time_of_day is int, with a default of NULL.

• [ @job_login= ] 'job_login'
  Is the Microsoft Windows Account under which the Snapshot Agent runs when generating the snapshot for a subscription using a parameterized row filter. job_login is nvarchar(257), with a default value of NULL.

• [ @job_password= ] 'job_password'
  Is the password for the Windows Account under which the Snapshot Agent runs when generating the snapshot for a subscription using a parameterized row filter. job_password is nvarchar(257), with a default value of NULL.
