OracleException Class

The exception that is generated when a warning or error is returned by an Oracle database or the .NET Framework Data Provider for Oracle. This class cannot be inherited.

Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

[SerializableAttribute] 
public sealed class OracleException : DbException
/** @attribute SerializableAttribute() */ 
public final class OracleException extends DbException
SerializableAttribute 
public final class OracleException extends DbException

This class is created whenever the OracleDataAdapter encounters a situation that it cannot handle.

If the severity of the error is too great, the server may close the OracleConnection. However, the user can reopen the connection and continue.

The following example generates an OracleException due to a missing database, and then displays the exception.

public void ShowOracleException() 
{
   OracleConnection myConnection =
      new OracleConnection("Data Source=Oracle8i;Integrated Security=yes");

   try 
   {
      myConnection.Open();
   
   catch (OracleException e) 
   {
     string errorMessage = "Code: " + e.Code + "\n" +
                           "Message: " + e.Message;

     System.Diagnostics.EventLog log = new System.Diagnostics.EventLog();
     log.Source = "My Application";
     log.WriteEntry(errorMessage);
     Console.WriteLine("An exception occurred. Please contact your system administrator.");
