Re: [Cppcms-users] CppDB: Return selected rows count

[Artyom B. <art...@gm...>]

The problem with the number of rows is that in many APIs it isn't
known in advance.

For example sqlite3 and mysql fetches row by row until you get to the
end of the query.
You can store the entire result but it may be costly - and it isn't
done by default.

So the number of rows in advance can be used for only in limited set of drivers.
