Method, system, and program for optimized parameter binding

摘要

Disclosed is a technique for input parameter binding. When executing a statement, data in an application structure of the statement is compared with optimization information in a bind-in structure. When there is a match between the data in the application structure and data in the optimization information in the bind-in structure, the statement is executed with the optimization information. Also disclosed is a technique for output parameter binding. When executing a statement, data in an application structure of the statement is compared with optimization information in a bind-out structure. When there is a match between the data in the application structure and data in the optimization information in the bind-out structure, the statement is executed with the optimization information.
