SqlTraits_impl.h:49: error: 'read' is not a member of 'Wt::Dbo::sql_value_traits<Wt::WString, void>' Wt 3.3.0
Added by Alistair Lowe almost 11 years ago
Hi guys,
A little bit of an odd one here. I have a class that extends WContainerWidget and within this is the attribute:
dbo::QueryModel<WString> linkBoxColumnModel;
Despite using a standard WString result type, I'm receiving the following compile errors, which are caused purely by the presence of this attribute.
/usr/include/Wt/Dbo/SqlTraits_impl.h: In instantiation of 'static Result Wt::Dbo::query_result_traits<Result>::load(Wt::Dbo::Session&, Wt::Dbo::SqlStatement&, int&) [with Result = Wt::WString]':

/usr/include/Wt/Dbo/SqlTraits_impl.h:49:3: error: 'read' is not a member of 'Wt::Dbo::sql_value_traits<Wt::WString, void>'
The reason I'm finding this odd is that I've used this exact approach elsewhere in my code with it working perfectly.
Any ideas?
Many thanks

#include ?
BR,

I'm afraid not, I have the following files included in the same header:
#include <Wt/WSignal>
#include <Wt/WString>
#include <Wt/Dbo/Dbo>
#include <Wt/Dbo/SqlTraits_impl.h>
#include <Wt/Dbo/SqlTraits>
#include <Wt/Dbo/Session>
#include <Wt/Dbo/Query>
#include <Wt/Dbo/QueryModel>
#include <Wt/WContainerWidget>
#include <Wt/WHBoxLayout>
#include <Wt/WComboBox>
#include <Wt/WLineEdit>
#include <Wt/WPushButton>
SqlTraits_impl.h is out of desperation of course.

Ah my apologies, I didn't realise there was separate WtSqlTraits header file.
Many thanks
