This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The RemoveJobsByLogin method drops all SQL Server Agent jobs owned by the login identified and removes the referencing Job objects from the Jobs collection.
By default, any SQL Server login has membership, through the user guest, in the public role of the system database maintaining SQL Server Agent jobs (msdb). When a SQL Server user is created in msdb, jobs created by the user mapping the login are owned by the login, not the user.
|Removing SQL Server Agent jobs by using the RemoveJobsByLogin method requires appropriate privilege. The SQL Server login used for SQLServer object connection must be the login indicated in the Login argument and having a job ownership privilege or a member of a role with greater permission.|
