  • Patent number: 11868502
    Abstract: Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.

  • Patent number: 11868605
    Abstract: A method includes invoking, by a user through continuous sliding, a first application bar and a second application bar that includes more application icons than the first application bar, to help the user perform an operation on an application icon included in the first application bar or the second application bar to quickly start an application. In addition, the method is further combined with a return function. After a first identifier appears, for example, when a first slide gesture goes to a second point, if a touch point of the user leaves a screen, an electronic device performs the return function, for example, display an interface previous to a first interface on a display, or the electronic device performs a function of returning to a home screen, for example, display the home screen of the electronic device on a display.
