HI,
ADO have nothing to do with JOIN, the JOIN is first made, then, the
result "encapsulated" into a recordset. The following should work:
Dim rst As ADODB.Recordset
Set rst=xnn.Execute("SELECT COUNT(*) FROM a LEFT OIN b ON a.f1=b.g1")
Debug.Print rst.Fields(0).Value
assuming xnn is an already open ADO connection.
Hoping it may help,
