My biggest problem with this is to get the string value from the class you have to use the concrete type, using var will retu... | stackexchange/codereview |

Users are free to provide any type that supports required semantics. It also supports traverse performance of std::vector du... | stackexchange/codereview |

SELECT CONCAT(DATE_FORMAT(start_date, '%Y'), ',',
(MONTH(start_date) -1), ',', DATE_FORMAT(start_date, '%d')) as start_date
FROM PROJECTS
