Does it work with
Code: Select all  Expand view  RUN
oRs = CREATEOBJECT( "ADODB.Recordset" )
oRs :cursortype :=1
oRs :cursorlocation :=3
oRs :locktype := 3  
oRs:open("select * from mytable",oConexion)

Lucas,

That's strange, I'm just tested it with a table with about 64000 records without any problem.

Marc

Marc,

It Works with these settings:

LOCAL oRs := CreateObject("ADODB.recordset")

WITH OBJECT oRs
:CursorLocation := 2
:CursorType := 1
//
END


Very strange
Muchas gracias. Many thanks.

I am using mysql odbc driver 5.1 with ado.
I am able to retrieve full record set ( 3000 rows ).
I am using fwh functions.

Sample
Code: Select all  Expand view  RUN
static oCn

//----------------------------------------------------------------------------//

function Main()

   local oRs

   ADOCONNECT oCn TO MySQL SERVER localhost DATABASE FWH USER root PASSWORD <mypassword>
   oRs   := FW_OpenRecordSet( oCn, "LARGETAB" )
   oRs:MoveLast()
   XBROWSER oRs
   oRs:Close()
   oCn:Close()

return nil
