摘要: Memory usage of a database driver is reduced by accessing database elements from a database object within a database during a database operation, generating an element object for each different value of accessed database elements, where the database object includes at least two database elements having the same unique value such that a total number of accessed database elements is greater than a total number of generated element objects, storing the generated element objects in a storage structure, and providing the generated element objects from the storage structure within results for the database operation.
