DB2Error Class

Inheritance hierarchy

Syntax

[Visual Basic]
<Serializable>
NotInheritable Public Class DB2Error
[C#]
[Serializable]
public sealed class DB2Error
[C++]
[Serializable]
public __gc __sealed class DB2Error
[JScript]

   Serializable
class DB2Error

Remarks

An instance of this class is created whenever an error occurs on a database operation in your application. Each instance of DB2Error created by the DB2DataAdapter is then managed by the DB2®ErrorCollection class, which in turn is created by the DB2Exception class.

If the severity of the error is too great, the server can close the DB2Connection. If the server does close the connection, the application will need to open a new connection.

Example

[Visual Basic, C#] The following example displays the properties of the DB2Error.

[Visual Basic]
Public Sub DisplayDB2ErrorCollection(myException As DB2Exception)
    Dim i As Integer
    For i = 0 To myException.Errors.Count - 1
        MessageBox.Show("Index #" + i.ToString() + ControlChars.Cr _
           + "Message: " + myException.Errors(i).Message + ControlChars.Cr _
           + "Native: " + myException.Errors(i).NativeError.ToString() 
                        + ControlChars.Cr _
           + "Source: " + myException.Errors(i).Source + ControlChars.Cr _
           + "SQL: " + myException.Errors(i).SQLState + ControlChars.Cr)
    Next i
End Sub

[C#]
public void DisplayDB2ErrorCollection(DB2Exception myException)
{
   for (int i=0; i < myException.Errors.Count; i++)
   {
      MessageBox.Show("Index #" + i + "\n" +
             "Message: " + myException.Errors[i].Message + "\n" +
             "Native: " + myException.Errors[i].NativeError.ToString() + "\n" +
             "Source: " + myException.Errors[i].Source + "\n" +
             "SQL: " + myException.Errors[i].SQLState + "\n");
   }
}
