You cannot convert an unsigned char
to/from SQL.
Converting this type may seem simple enough, but it's ambiguous: Did you mean the char
value as a small integer? Or were you thinking of a single-character string (and if so, using 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
or unsigned int
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 pqxx::bytes_view
instead.
