users could do
boost::mysql::row
row; while (result.async_read_one(row, additional_info, yield[ec])) avoiding unnecessary further copies. In principle it would be even possible to parse directly in a custom data structure, for example, when storing json string in the database.
i've developed a small C++17 example of how to work with Input/Output transformers to write the statements more compact and type-safe the base idea is that the MySQL <-> C++ needs sometimes some sort of conversions and to combine most of the infos at one point so its easier or at least possible to optimize better - the current interface looks very runtime allocation stylish :) the Input- and Output Transformers help to work with basic types and also with SQL/MySQL special types like Null-string etc. - its not possible to map MySQL types always 1:1 to C++ and back, sometimes you want to behave the transformation different the Transformers aren't visible when used with basic types its just an example to promote the Idea: https://pastebin.com/raw/vepbTAKL the best combination would be some sort of fluent SQL interface like: https://github.com/rbock/sqlpp11 but i still think a plain string+binding interface like Boost.MySql currently got is also needed
