Hi @dend456, Thanks a lot, this is great! And thanks for providing unit-tests without me asking for it :) Cheers! |

Np, do you think a function that fills a std::vector from all rows in the result would be useful? |

Well, it could, but the problem are:
(what I mean is that this could lead to a complex template with multiple paramters) |

Added a template function that allows you to retrieve all columns (or first N columns) of a row as an object. Extremely convenient when working with a table that has a large number of columns. Instead of having to do:
int i0 = query.getColumn(0);
int i1 = query.getColumn(1);
...
int i39 = query.getColumn(39);
then passing all those temporary variables into a constructor, you can do:
auto i = query.getColumns<MyClass, 40>();
where MyClass has a constructor that takes 40 arguments that are convertible from a Column object.
