Template Template Parameter and Template Traits

[D_Drmmr]

soci::backend_factory const& backEnd = sqlite3;

This statement was working

but when i pass in the soci::sqlite3 statement into the trait class, compiler complaints that soci::sqlite3 is not a type.

soci::sqlite3 is an object, not a statement.
Pass into which traits class? How do you pass an object into a class? You can pass a type to a template class or you can pass an object to a function (possibly a constructor).

Please help.

Thanks.

I think you'll get a lot more help if you post a minimal but complete example that replicates your problem.
