Делаю кнопку с отчетом по вашим примерам. пишет: unrecognized token {

вот тело кнопки:

SELECT
strftime('%d.%m.%Y',audiorols.date) as date,
strftime('%d.%m.%Y' ,{dtFrom}) as datefrom,
strftime('%d.%m.%Y' ,{dtTo}) as dateto,
audiorols.rolname,
audiorols.vihodi,
audiorols.date_from,
audiorols.date_to,
audiorols.europes,
audiorols.zaiavka,
status.status_rol,
managers.name_manager,
clients.clients_name

FROM audiorols
LEFT OUTER JOIN clients ON clients.id=audiorols.id_clients
LEFT OUTER JOIN managers ON managers.id=audiorols.id_managers
LEFT OUTER JOIN status ON status.id=audiorols.id_status

WHERE

(audiorols.date_from >=  {dtFrom}) AND (audiorols.date_to <={dtTo})
