Each RWDBOSql object corresponds to a CS_COMMAND structure. A CS_COMMAND structure is created and associated with an RWDBOSql object only when the execute() method is invoked on the RWDBOSql object. The CS_COMMAND structure remains associated with the RWDBOSql object until it goes out of scope, or until execute() is invoked on the object using a different connection. Invoking execute() on the same connection reuses the same CS_COMMAND structure.
