Замечания

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.
