備註

SQL Server Agent jobs contain one or more execution units called steps. Each job step contains a textual command, type of execution that specifies command interpretation, and logic that determines the behavior of the job if the step succeeds or fails. For example, a job step can contain:

  • The command text. For example:

    DBCC CHECKDB ('Northwind') WITH NO_INFOMSGS
    
  • A job step execution type: Transact-SQL for example.

  • An indication that the job should stop if the step fails.

With the JobStep object, you can do the following:

  • Create a SQL Server Agent job step.

  • Remove a job step from a SQL Server Agent job.

  • Manage existing job steps by changing, for example, the command text or the actions taken on success or failure of the step.

  • Obtain details about the last attempted execution of the step.

To get JobStep object properties, users must be a member of SQLAgentUserRole database role on the MSDB database or be a member of the sysadmin fixed server role.

To set JobStep object properties, users must be a member of SQLAgentUserRole database role on the MSDB database, be the owner of the owner of the job step, or be a member of the sysadmin fixed server role.

To create a job step, users must be a member of SQLAgentUserRole database role on the MSDB database or be a member of the sysadmin fixed server role. The user must also have permission on any proxy accounts used by the job step.

To drop a job step, users must be a member of SQLAgentUserRole database role on the MSDB database, be the owner of the job step, or be a member of the sysadmin fixed server role.
