OracleGlobalization Class

The OracleGlobalization class is used to obtain and set the Oracle globalization settings of the session, thread, and local computer (read-only).

Class Inheritance

Object

  OracleGlobalization

Declaration

public sealed class OracleGlobalization : ICloneable, IDisposable

Thread Safety

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

Remarks

An exception is thrown for invalid property values. All newly set property values are validated, except the TimeZone property.

Changing the OracleGlobalization object properties does not change the globalization settings of the session or the thread. Either the SetSessionInfo method of the OracleConnection object or the SetThreadInfo method of the OracleGlobalization object must be called to alter the session's and thread's globalization settings, respectively.

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class OracleGlobalizationSample
{
  static void Main()
  {    
    // Get thread's globalization info
    OracleGlobalization glob = OracleGlobalization.GetThreadInfo();
    
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    // Set language on thread's globalization info
    glob.Language = "FRENCH";
    OracleGlobalization.SetThreadInfo(glob);
    OracleGlobalization.GetThreadInfo(glob);
 
    // Prints "glob.Language = FRENCH"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    glob.Dispose();
  }
}

GetClientInfo

GetClientInfo returns an OracleGlobalization object instance that represents the Oracle globalization settings of the local computer.

Overload List:

• GetClientInfo()

  This method returns an OracleGlobalization instance that represents the globalization settings of the local computer.

• GetClientInfo(OracleGlobalization)

  This method refreshes the provided OracleGlobalization object with the globalization settings of the local computer.

GetClientInfo()

This method returns an OracleGlobalization instance that represents the globalization settings of the local computer.

Declaration

// C#
public static OracleGlobalization GetClientInfo();

Return Value

An OracleGlobalization instance.

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class GetClientInfoSample
{
  static void Main()
  {
    // Get client's globalization info
    OracleGlobalization glob = OracleGlobalization.GetClientInfo();
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    glob.Dispose();
  }
}

GetClientInfo(OracleGlobalization)

This method refreshes the provided OracleGlobalization object with the globalization settings of the local computer.

Declaration

// C#
public static void GetClientInfo(OracleGlobalization oraGlob);

Parameters

• oraGlob

  The OracleGlobalization object being updated.

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class GetClientInfoSample
{
        static void Main()
        {    
    // Get client's globalization info
    OracleGlobalization glob = OracleGlobalization.GetClientInfo();
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
    
    // Get client's globalization info using overload
    OracleGlobalization.GetClientInfo(glob);
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    glob.Dispose();
        }
}

GetThreadInfo

GetThreadInfo returns or refreshes an OracleGlobalization instance.

Overload List:

• GetThreadInfo()

  This method returns an OracleGlobalization object instance of the current thread.

• GetThreadInfo(OracleGlobalization)

  This method refreshes the OracleGlobalization object instance with the globalization settings of the current thread.

GetThreadInfo()

This method returns an OracleGlobalization instance of the current thread.

Declaration

// C#
public static OracleGlobalization GetThreadInfo();

Return Value

An OracleGlobalization instance.

Remarks

Initially, GetThreadInfo() returns an OracleGlobalization object that has the same property values as that returned by GetClientInfo(), unless the application changes it by invoking SetThreadInfo().

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class GetThreadInfoSample
{
  static void Main()
  {    
    // Get thread's globalization info
    OracleGlobalization glob = OracleGlobalization.GetThreadInfo();
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    // Get thread's globalization info using overloaded
    OracleGlobalization.GetThreadInfo(glob);
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    glob.Dispose();
  }
}

GetThreadInfo(OracleGlobalization)

This method refreshes the OracleGlobalization object with the globalization settings of the current thread.

Declaration

// C#
public static void GetThreadInfo(OracleGlobalization oraGlob);

Parameters

• oraGlob

  The OracleGlobalization object being updated.

Remarks

Initially GetThreadInfo() returns an OracleGlobalization object that has the same property values as that returned by GetClientInfo(), unless the application changes it by invoking SetThreadInfo().

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class GetThreadInfoSample
{
  static void Main()
  {    
    // Get thread's globalization info
    OracleGlobalization glob = OracleGlobalization.GetThreadInfo();
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    // Get thread's globalization info using overloaded
    OracleGlobalization.GetThreadInfo(glob);
 
    // Prints "glob.Language = AMERICAN"
    Console.WriteLine("glob.Language = " + glob.Language);
 
    glob.Dispose();
  }
}

SetThreadInfo

This method sets Oracle globalization parameters to the current thread.

Declaration

// C#
public static void SetThreadInfo(OracleGlobalization oraGlob);

Parameters

• oraGlob

  An OracleGlobalization object.

Remarks

Any .NET string conversions to and from Database Change Notification Types, as well as ODP.NET Type constructors, use the globalization property values where applicable. For example, when constructing an OracleDate structure from a .NET string, that string is expected to be in the format specified by the OracleGlobalization.DateFormat property of the thread.

Example

// C#
 
using System;
using Oracle.DataAccess.Client;
 
class SetThreadInfoSample
{
  static void Main()
  {
    // Get thread's globalization info
    OracleGlobalization glob1 = OracleGlobalization.GetThreadInfo();
    
    // Prints "glob1.Language = AMERICAN"
    Console.WriteLine("glob1.Language = " + glob1.Language);
 
    // Set language on thread's globalization info
    glob1.Language = "FRENCH";
    OracleGlobalization.SetThreadInfo(glob1);
    OracleGlobalization glob2 = OracleGlobalization.GetThreadInfo();
 
    // Prints "glob2.Language = FRENCH"
    Console.WriteLine("glob2.Language = " + glob2.Language);   
 
    glob1.Dispose();
    glob2.Dispose();
  }
}

TimeZone can be either an hour offset, for example, 7:00, or a valid time zone region name that is provided in V$TIMEZONE_NAMES, such as US/Pacific. Time zone abbreviations are not supported.

This property returns an empty string if the OracleGlobalization object is obtained using GetSessionInfo() or GetSessionInfo(OracleGlobalization). Initially, by default, the time zone of the session is identical to the time zone of the thread. Therefore, given that the session time zone is not changed by invoking ALTER SESSION calls, the session time zone can be fetched from the client's globalization settings.
