I thought that it should be "easy enough" to add a custom function that outputs the formatted view for numbers... so, instead of > select int_val you could do: > select to_thousands_formatted(int_val) with an optional parameter that says how you want it separated "," being the default. It would be a bit like using upper(X) with a syntax that uses parameters like group_concat() does. Would that not work? In that case, this pretty_printer coule be code only within the sqlite3 shell (or as an extension, it could be in anything). Best Regards, Mohit.
