Abstract: The present application discloses a method, system, and computer system for enforcing security with respect to a database. The system includes a database configured to receive a query, wherein the query is modified to comprise one or more security predicates; determine data to return in response to the query by examining the one or more security predicates with respect to security for a field; and return the determined data in response to the query.

Abstract: In some implementations, the techniques described herein relate to a method including: receiving, by a query engine, a database query, the database query including an inner query having inner query conditions and an outer query having outer query conditions; determining, by the query engine, that a number of rows responsive to the outer query exceeds a threshold; determining, by the query engine, that the inner query conditions and the outer query conditions are correlated; rewriting, by the query engine, the inner query conditions to include at least one of the outer query conditions to generate an optimized query; and executing, by the query engine, the optimized query on a database.

Abstract: The present application discloses a method, system, and computer system for enforcing security with respect to a database. The method includes receiving, by one or more processors, a user query from a user, determining one or more user security privileges for the user, configuring a query string, querying a database to return results based at least in part on the query string, obtaining the results, and providing the results to the user. The query string is based at least in part on the user query, and the query string comprises one or more security predicates that are based at least in part on the one or more user security privileges.

Abstract: A height adjustable vehicle transport trailer includes a frame having a front end, a back end, and a pair of sides, a draw bar slidably affixed to the front end, a deck affixed to the frame, a pair of brackets each affixed to one pair of sides, each pair of brackets having a swing arm, configured with a first end rotationally hingedly affixed the frame and a second end removeably pinned therein said one of the brackets, a wheel rotationally affixed to an axle, the axle affixed to said swing arm, and a plurality of lift mechanisms affixed to the frame to provide a vertically adjustable trailer.
