OracleIntervalYM Structure

The OracleIntervalYM structure represents the Oracle INTERVAL YEAR TO MONTH data type to be stored in or retrieved from a database. Each OracleIntervalYM stores a period of time in years and months.

Class Inheritance

System.Object

  System.ValueType

    Oracle.DataAccess.Types.OracleIntervalYM

Declaration

// C#
public struct OracleIntervalYM : IComparable

Thread Safety

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

Example

// C#
 
using System;
using Oracle.DataAccess.Types;
 
class OracleIntervalYMSample
{
  static void Main()
  {
    OracleIntervalYM iYMMax = OracleIntervalYM.MaxValue;
    double totalYears = iYMMax.TotalYears;
 
    totalYears -= 1;
    OracleIntervalYM iYMMax_1 = new OracleIntervalYM(totalYears);
    
    // Calculate the difference
    OracleIntervalYM iYMDiff = iYMMax - iYMMax_1;
    
    // Prints "iYMDiff.ToString() = +000000001-00"
    Console.WriteLine("iYMDiff.ToString() = " + iYMDiff.ToString());
  }
}
