The Object Version supports the Object Extension through the TOracleObject and TOracleReference classes. These classes encapsulate user defined object types, and are used to access its attributes and methods. See the TOracleObject section in the User's Guide for additional details.
The Standard Version does not have these classes, and consequently you cannot:
Access object instances through the TOracleDataSet and TOracleQuery components
Use the TXMLType class
Use a TOracleQueue based on an object queue (only raw queues are available in the standard version)
