1) overloads of operator<< and operator, It confuses me to use operator<< to get information _out_ of something.
Ok, but I don't think SOCI does that. It uses operator<< on an SQL statement to bind variables -- the variables can be input or output depending on what you're doing.
Well, not exactly. :-) string name; int id = ...; sql << "select name from persons where id = :id", into(name), use(id); Above: - operator<< is used to *send* query to the server, - "into element" is used to bind variable that will get results, - "use element" binds variable that provides data for the query, - operator, is used to bunch all parts of the query together. In other words, operator<< is not used to "get something out" (into elements serve this purpose instead), but to "make things happen". -- Maciej Sobczak * www.msobczak.com * www.inspirel.com
