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

<SerializableAttribute> _
Public NotInheritable Class OracleException
	Inherits DbException
Dim instance As OracleException

/** @attribute SerializableAttribute() */ 
public final class OracleException extends DbException
public final class OracleException extends DbException
Not applicable.

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 Sub ShowOracleException() 

   Dim myConnection As OracleConnection = _
      New OracleConnection("Data Source=Oracle8i;Integrated Security=yes")



   Catch e As OracleException

     Dim errorMessage As String = "Code: " & e.Code & vbCrLf & _
                                  "Message: " & e.Message

     Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog()
     log.Source = "My Application"
     Console.WriteLine("An exception occurred. Please contact your system administrator.")

   End Try
End Sub
