Use this page to set permissions on database securables for this user, database role or application role. Click Add to add database securables to the Securables grid. Then select a securable in the grid and set the appropriate permissions in the Explicit permissions grid.
This page only shows permissions that are explicitly granted or denied to this user or role. The principal may inherit additional permissions through membership in a group or role. Permissions inherited from a group or role are not listed in the grid. The sum of all of the explicit and implicit permissions of the principal constitutes its effective permissions.
