LastServerErr Property Example

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
