Using functions to write back recordset?

Hello,
i use the macro function sc_select(rs,‘Select …’) returning an ADOrecordset.
Some fields will be changed like
{rs}->fields[‘test1’] = ‘Test1’;
{rs}->fields[‘test2’] = ‘Test2’;
Now i would like use something like the ADOdb function getUpdateSQL to write back the recordset.
How i can do that??

Thanks for any help!
