An OracleXmlSaveProperties object represents the XML properties used by the OracleCommand class when the XmlCommandType property is Insert, Update, or Delete.

Class Inheritance

System.Object

  System.OracleXmlSaveProperties

Declaration

public sealed class OracleXmlSaveProperties : ICloneable

Requirements

Thread Safety

All public static methods are thread-safe, although instance methods do not guarantee thread safety.

Remarks

OracleXmlSaveProperties can be accessed and modified using the XmlSaveProperties property of the OracleCommand class. Each OracleCommand object has its own instance of the OracleXmlSaveProperties class in the XmlSaveProperties property.

Use the default constructor to get a new instance of OracleXmlSaveProperties. Use the OracleXmlSaveProperties.Clone() method to get a copy of an OracleXmlSaveProperties instance.

Example

This sample demonstrates how to do inserts, updates, and deletes to a relational table or view using an XML document.
