OracleBoolean Structure

The OracleBoolean structure represents a logical value that is either TRUE or FALSE.

Class Inheritance

System.Object

  System.ValueType

    Oracle.DataAccess.Types.OracleBoolean

Declaration

// C#
public struct OracleBoolean : IComparable, INullable, IXmlSerializable

Requirements

Provider ODP.NET, Unmanaged Driver
Assembly Oracle.DataAccess.dll
Namespace Oracle.DataAccess.Types
.NET Framework 3.5, 4.0, 4.5

Thread Safety

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

Remarks

A OracleBoolean structure represents three possible values: TRUE, FALSE, and NULL. A non-zero value is interpreted as TRUE.

Example

// C#
using System;
using System.Data;
using Oracle.DataAccess.Types;
 
 class OracleBooleanSample
 {
    static void Main(string[] args)
    {
      OracleBoolean oracleBoolean1 = new OracleBoolean(true);
      OracleBoolean oracleBoolean2 = new OracleBoolean(0);
 
      Console.WriteLine("oracleBoolean1 : " + oracleBoolean1);
      Console.WriteLine("oracleBoolean2 : " + oracleBoolean2);
    }
 }
