What I don get is, in what moment the one that reads the advance should be issued? And how can I know that the lengthy query is completed?

So, I guess I should do something like this:
lnConn= SQLCONNECT('myOdbcDsn', 'myUserId', 'myPassword')
SQLSETPROP(lnConn, 'Asynchronous', .T.)
DO WHILE SQLEXEC(lnConn, 'SELECT * FROM myOrders', 'myCursor') = 0
   ** Show user something...
   ** Update progressbar...
ENDDO
** Continue program flow.
If my example is correct, how can I know whether the long query terminated fine (returned 1) or not (returned -1) after the DO...WHILE loop?.

TIA.
