Этот параметр должен устанавливать пользователь(в плане софта) драйвера и ожидать что драйвер отдаст более 1 строки.
если просто так его увеличить - что-нибудь поломается

Ребята, ситуация имеет место быть. Если надо забрать много строк, то это драйвер только помешает задаче.
Если вы хотите подучить ответ и он читаем сверднестатистическим человеком, то можете игнорировать это.
Если ваш ответ из миллионов строк, то не смотрите на этот ODBC драйвер. Разрабы уверены что он работает оптимально, а на самом дел вас може ждать максимум 1 Mbs.
