    Do not store authentication information in script files. For best security, login names and passwords should be supplied at runtime.
  • [ @job_name= ] 'job_name'
    Is the name of an existing agent job. job_name is sysname, with a default value of NULL. This parameter is only specified when the agent is created using an existing job instead of a newly created job (the default).
  • [ @frompublisher= ] frompublisher
    Specifies whether the procedure is being executed at the Publisher. frompublisher is bit, with a default value of 0. A value of 1 means that the procedure is being executed from the Publisher on the publication database.
