Question

I am trying to extract the data with ADODB connection through VBA but when i run throgh this code recset.Open strSQL, con, adOpenKeyset, adLockOptimistic
my excel is automatically getting closed.
Is there anything which i am missing?
Sub Show_data()
Dim con As ADODB.Connection
Dim recset As ADODB.Recordset
Dim ConnectionString As String
Dim strSQL As String
Set con = New ADODB.Connection
Set recset = New ADODB.Recordset
'Check for the connectivity or connected to the xx network
On Error GoTo errHandler
errHandler:
If Err.Number = -2147467259 Then
MsgBox "Please check for the xx connectivity ", vbExclamation + vbOKOnly
Exit Sub
End If
ConnectionString = "Provider=MSDASQL;User ID=myuser;password= mypass;Data Source=mys"
con.Open ConnectionString
'Set and Excecute SQL Command'
strSQL = "SELECT B.USER_NAME AS CREATED_BY, A.CREATION_DATE, C.USER_NAME, A.LAST_UPDATE_DATE, A.PFIZER_ITEMCODE, A.SYSTEM_ITEMCODE AS ORACLE_ITEM_CODE, " & _

End If
recset.Close
con.Close
End Sub

The issue may be with your connection's cursor location, by default it is adUseServer. When using keyset, you will probably want to use adUseClient. I know from using ms access that this is especially the case when attempting to bind the recordset to a form. Try opening the connection with adUseClient, hopefully it will resolve your issue.
