In reply to Nemanja Boric. Yep good idea, it does make code simpler. I reworked the article to include it. Thanks Nemanja!

Easy way to get out of `addFieldToQuery` is to make the first part of the query

“`
SELECT * FROM persons WHERE 1=1
“`

and then you don’t need to threat the first entry as a special case.

In reply to kaduim. Absolutely. Thanks for pointing this out, this is now corrected.

Hello.

There is typo in:

std::string gender = “male”;
std::string nationality = “”;
std::string eyeColor = “blue”;
buildQuery(gender, boost::none, eyeColor);

Last line should be:

buildQuery(gender, nationality, eyeColor);
