Re: [Cppcms-users] cppdb::statement.affected() usage?

It will save users much time if this behavior is documented.

Also, it will be handy if the number of selected rows (returned by libpq's  
PQntuples()) is implemented in either cppdb::statement or cppdb::result.  
Without this feature, it seems that iterating cppdb::result (by calling  
next()) is the only available way to know the number of selected rows.  
Wrong?
