Detailed Description
You cannot convert a signed char to/from SQL.
Converting this type may seem simple enough, but it's ambiguous: Did you mean the value as a small integer? Or were you thinking of a single-character string (and if so, in what encoding)? Or perhaps it's just a raw byte value?
If you meant it as an integer, use an appropriate integral type such as int or short etc.
If you wanted a single-character string, use std::string_view (or a similar type such as std::string).
Or if you had a raw byte in mind, try std::basic_string_view<std::byte> instead.
