Detailed Description

Function Documentation

template<typename ITER , typename ACCESS >

std::string pqxx::separated_list ( std::string_view  sep, ITER  begin, ITER  end, ACCESS  access  )

inline

Represent sequence of values as a string, joined by a given separator.

Use this to turn e.g. the numbers 1, 2, and 3 into a string "1, 2, 3".

Parameters

sep	separator string (to be placed between items)
begin	beginning of items sequence
end	end of items sequence
access	functor defining how to dereference sequence elements
