Content type: text/plain
Description: An usage example
Class: DATA
Access data stored in MySQL tables like arrays
Author: By
Last change: v0.8:
- changed how array offsets are mapped to the conditions of selecting a row (for possible security problems). If available, an unique field is used, and access using the pk is provided using the special property ->byXXXX
- abstraction of sql data types and inboxing of these values into objects with constraints checking
- disabling of inboxing of sql data types is available through property ->withoutInboxing
- new exceptions hierarchy (allows more fine-grained catching of exceptions)
