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

[CN <cn...@gr...>]

Hello!

The following SELECT gets one tuple:

cppdb::statement st=session << "SELECT 1 FROM t1";
cppdb::result r=st.row();

Now, r.empty() returns false, which is correct, but st.affected() returns  
0.

cppdb::statement.affected() is supposed to return the selected number of  
tuples, which is 1 in this case, not 0.

Do I misunderstand its usage?

Thank you in advance!
