OracleTimeStamp Structure

The OracleTimeStamp structure represents the Oracle TIMESTAMP data type to be stored in or retrieved from a database. Each OracleTimeStamp stores the following information: year, month, day, hour, minute, second, and nanosecond.

Class Inheritance

System.Object

  System.ValueType

    Oracle.DataAccess.Types.OracleTimeStamp

Declaration

// ADO.NET 2.0: C#public struct OracleTimeStamp : IComparable, INullable, IXmlSerializable

// ADO.NET 1.x: C#
public struct OracleTimeStamp : IComparable, INullable

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 OracleTimeStampSample
{
  static void Main()
  {
    OracleTimeStamp tsCurrent1 = OracleTimeStamp.GetSysDate();
    OracleTimeStamp tsCurrent2 = DateTime.Now;
    
    // Calculate the difference between tsCurrent1 and tsCurrent2
    OracleIntervalDS idsDiff = tsCurrent2.GetDaysBetween(tsCurrent1);
    
    // Calculate the difference using AddNanoseconds()
    int nanoDiff = 0;
    while (tsCurrent2 > tsCurrent1)
    {
      nanoDiff += 10;
      tsCurrent1 = tsCurrent1.AddNanoseconds(10);
    }
    Console.WriteLine("idsDiff.Nanoseconds = " + idsDiff.Nanoseconds);
    Console.WriteLine("nanoDiff = " + nanoDiff);
  }
}

Remarks

The following rules apply to the behavior of this method.

• The comparison must be between OracleTimeStamps. For example, comparing an OracleTimeStamp instance with an OracleBinary instance is not allowed. When an OracleTimeStamp is compared with a different type, an ArgumentException is thrown.

• Any OracleTimeStamp that has a value is greater than an OracleTimeStamp that has a null value.

• Two OracleTimeStamps that contain a null value are equal.

public override bool Equals(object obj);

Parameters

• obj

  The object being compared to the current OracleTimeStamp instance.

Return Value

Returns true if the obj is of type OracleTimeStamp and represents the same date and time; otherwise, returns false.

Remarks

The following rules apply to the behavior of this method.

• Any OracleTimeStamp that has a value is greater than an OracleTimeStamp that has a null value.

This method converts the current OracleTimeStamp structure to a string.

Declaration

// C#
public override string ToString();

Return Value

A string that represents the same date and time as the current OracleTimeStamp structure.

Remarks

The returned value is a string representation of an OracleTimeStamp in the format specified by the OracleGlobalization.TimeStampFormat property of the thread.

The names and abbreviations used for months and days are in the language specified by the OracleGlobalization's DateLanguage and Calendar properties of the thread. If any of the thread's globalization properties are set to null or an empty string, the client computer's settings are used.

Example

// C#
 
using System;
using Oracle.DataAccess.Types;
using Oracle.DataAccess.Client;
 
class ToStringSample
{
  static void Main()
  {
    // Set the nls_timestamp_format for the OracleTimeStamp(string)
    // constructor
    OracleGlobalization info = OracleGlobalization.GetClientInfo();
    info.TimeStampFormat = "DD-MON-YYYY HH:MI:SS.FF AM";
    OracleGlobalization.SetThreadInfo(info);
    
    // construct OracleTimeStamp from a string using the format specified.
    OracleTimeStamp ts = new OracleTimeStamp("11-NOV-1999 11:02:33.444 AM");
    
    // Set the nls_timestamp_format for the ToString() method
    info.TimeStampFormat = "YYYY-MON-DD HH:MI:SS.FF AM";
    OracleGlobalization.SetThreadInfo(info);
 
    // Prints "1999-NOV-11 11:02:33.444000000 AM"      
    Console.WriteLine(ts.ToString());    
  }
