LastServerErr Property

Applies To

OraDatabase Object

OraSession Object


Returns the last nonzero error code generated by an Oracle database function for the specified object. Not available at design time and read-only at run time.


error_number = oradatabase.LastServerErr
error_number = orasession.LastServerErr

Data Type

Long Integer


This property represents the last nonzero return value from an Oracle Call Interface (OCI) database function, or zero if no error has occurred since the last LastServerErrReset request. For efficiency, only nonzero return values are returned; therefore, a nonzero value does not necessarily indicate that the most recently called OCI database function generated the error (because zero return values are not returned by way of the LastServerErr method).


This example demonstrates the use of the CreateDynaset method and the LastServerErr and LastServerErrText properties to determine whether an Oracle error has occurred, and to display the error message, respectively. Copy and paste this code into the definition section of a form. Then, press F5.

Sub Form_Load ()
 'Declare variables as OLE Objects.
 Dim OraSession As OraSession 
 Dim OraDatabase As OraDatabase 
 Dim OraDynaset As OraDynaset 
 'Create the OraSession Object.
 Set OraSession = CreateObject("OracleInProcServer.XOraSession")
 'Set up an error handler.
 On Error GoTo errhandler 
 'Create the OraDatabase Object by opening a connection to Oracle.
 Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&)
 'Attempt to Create the OraDynaset Object.
 'Notice that the FROM keyword is missing from the SQL statement.
 Set OraDynaset = OraDatabase.CreateDynaset("select * emp", 0&)
Exit Sub
 'Check to see if an Oracle error has occurred.
 If OraDatabase.LastServerErr <> 0 Then
  MsgBox OraDatabase.LastServerErrText
 Else 'Must be some non-Oracle error
  MsgBox "VB:" & Err & " " & Error(Err)
 End If
 Exit Sub
End Sub
