[Cppcms-users] statement::bind can be deceptive/dangerous

[<ele...@ex...>]

I was trying to figure out why

st.prepare(....)
....
st.bind(5, r.get<string>("date_action"));
....
st.exec()

in my code produces unpredictable behaviour untill I read in the
documentation that -

Note: the reference to the string MUST remain valid until the statement is
queried or executed!

In my code im copying some old rows into new rows and
r.get<string>("date_action") returns the letter "R" but after it got
binded to the new statement it was showing "l" which puzzled me to no-end
as to why, but if I did

string wtf = r.get<string>("date_action");
st.bind(5, wtf);

it worked fine.

Should statement::bind be using value instead of reference semantics?
