STL_SESSIONS

Returns information about user session history.

STL_SESSIONS differs from STV_SESSIONS in that STL_SESSIONS contains session history, where STV_SESSIONS contains the current active sessions.

This view is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.
