This example demonstrates the use of the LastServerErr and LastServerErrText
properties to determine whether an Oracle error has occurred using CreateDynaset
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
errhandler:
'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
