  • Two-level caching system for prepared SQL statements in a relational database management system
    Patent number: 6115703
    Abstract: A method, apparatus, and article of manufacture for a computer implemented two-level caching system. A statement is executed in a computer. The statement is executed by the computer to manipulate data in a database stored on a data storage device connected to the computer. Initially, a first statement is prepared to create an executable structure for executing the first statement from an application. Then, the executable structure is stored in an application-level cache associated with the application. A second statement is received for execution from the application. It is determined that the second statement can be executed using the stored executable structure for the first statement. Next, the second statement is executed using the stored executable structure.
