So, is this the expected behaviour?, am I/are we missing something about DAL?. Just for the record, I'm not that smart, when imported backup from table to db booleans were 0 and 1, but after editing the table in CSV format and restoring data to table noticed the difference and booleand were converted to T and F respectively. Hope it helps.
