    Hi poj

    Great. This works as expected. From DBI doc, I understand that DBI will do the type conversion for me from scalar automatically. Looks like in this case I need to do it manually. But why only for RHS? because LHS is doing addition, so it is converted to INTEGER automatically?

    Thanks :)

      Is your database field creationTime type INTEGER ?.

      You might find this statement works

      DELETE FROM session WHERE creationTime < ?

      if you make the parameter

      (time() - SESSION_MAX_LIFE_TIME)

      which I think is easier to understand
