OracleTimeStampLTZ Structure

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

Class Inheritance

System.Object

  System.ValueType

    Oracle.DataAccess.Types.OracleTimeStampLTZ

Declaration

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

// ADO.NET 1.x: C#

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;
using Oracle.DataAccess.Client;
 
class OracleTimeStampLTZSample
{
  static void Main()
  {
    // Illustrates usage of OracleTimeStampLTZ
    // Display Local Time Zone Name
    Console.WriteLine("Local Time Zone Name = " +
      OracleTimeStampLTZ.GetLocalTimeZoneName());
    OracleTimeStampLTZ tsLocal1 = OracleTimeStampLTZ.GetSysDate();
    OracleTimeStampLTZ tsLocal2 = DateTime.Now;
    
    // Calculate the difference between tsLocal1 and tsLocal2
    OracleIntervalDS idsDiff = tsLocal2.GetDaysBetween(tsLocal1);
    
    // Calculate the difference using AddNanoseconds()
    int nanoDiff = 0;
    while (tsLocal2 > tsLocal1)
    {
      nanoDiff += 10;
      tsLocal1 = tsLocal1.AddNanoseconds(10);
    }
    Console.WriteLine("idsDiff.Nanoseconds = " + idsDiff.Nanoseconds);

The OracleTimeStampLTZ structure contains the date and time in the OracleTimeStampTZ structure (which is normalized to the client local time zone).

Remarks

If the OracleTimeStampTZ structure has a null value, the returned OracleTimeStampLTZ structure also has a null value.

explicit operator OracleTimeStampLTZ(string)

This static type conversion operator converts the supplied string to an OracleTimeStampLTZ structure.

Declaration

// C#
public static explicit operator OracleTimeStampLTZ (string tsStr);

Parameters

• tsStr

  A string representation of an Oracle TIMESTAMP WITH LOCAL TIME ZONE.

Return Value

A OracleTimeStampLTZ.

Exceptions

ArgumentException - ThetsStr parameter is an invalid string representation of an Oracle TIMESTAMP WITH LOCAL TIME ZONE or the tsStr is not in the timestamp format specified by the thread's OracleGlobalization.TimeStampFormat property, which represents the Oracle NLS_TIMESTAMP_FORMAT parameter.

Remarks

The names and abbreviations used for months and days are in the language specified by the DateLanguage and Calendar properties of the thread's OracleGlobalization object. 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 OracleTimeStampLTZSample
{
  static void Main()
  {
    // Set the nls_timestamp_format for the OracleTimeStampLTZ(string)
    // constructor
    OracleGlobalization info = OracleGlobalization.GetClientInfo();
    info.TimeStampFormat = "DD-MON-YYYY HH:MI:SS.FF AM";
    OracleGlobalization.SetThreadInfo(info);
    
    // construct OracleTimeStampLTZ from a string using the format specified.
    OracleTimeStampLTZ ts = 
      new OracleTimeStampLTZ("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()); 
  }
}
