The documentation says, "This class is like an extended version of a
const std::vector of mysqlpp::String."
Each String in the Row holds the contents of one of the fields you
requested from the database from that row. So:
SELECT a, b, c FROM d
gives you three fields from all rows in table 'd', with each Row
having three fields called row, row, and row. Or, row["a"],
row["b"], and row["c"]. Each of these subscript accesses gives you a
String, which you generally don't use directly, but rather assign to
some compatible C++ type:
Row row = ...;
mysqlpp::sql_char a = row["a"];
mysqlpp::sql_int b = row["b"];
mysqlpp::sql_time c = row["c"];

Can you gave examples of the data you get from the DB, and a method
signature of the function you have to pass it to?

It's possible to convert each String field in the row to a vector of
char, but I'm going to hold off on telling you how until I get an
answer to the above. If you squint, mysqlpp::String and std::string
look like vectors of char, so any further translation is probably
