iterlib VS sqlpp11

I wrote such a C++ implementation during my days at Facebook around 8 years ago:

https://engineering.fb.com/2016/03/18/data-infrastructure/dr...

There is an example under "Functional programming primitives".

It was a C++ implementation that fell victim to Greenspun's 10th rule. So I wrote a specification for it, first in Clojure and then in python.

The C++ execution engine is open source:

Main problems writing such code:

* The output of SQL is generally flat. GraphQL makes it nested, but doesn't support all the operators SQL does natively.

sqlpp11 actually helps in this area (which imo is the most error prone area of using a database) and offers compile time query checking

I haven't used this, though I did see some presentations about it which got my interest: https://github.com/rbock/sqlpp11

If you love C++ Template magic look at https://github.com/rbock/sqlpp11

This allows "normal" C++ code, which by the compiler is converted into the query string, allowing code like

    for (const auto& row : db(select(all_of(foo)).from(foo).where(foo.hasFun or foo.name == "joker")))
