std::vector<soci::row>::resize() The specified type does not meet the requirements of Cpp17MoveInsertable

[kuvaldini]

      using namespace soci;
      constexpr int BATCH_SIZE = 30;
      std::vector<row> rows(BATCH_SIZE);
      statement st = (sql.prepare << "select * from table", into(rows));
      st.execute();
      while (st.fetch()) {
         std::vector<int>::iterator pos;
         for (pos = valsOut.begin(); pos != valsOut.end(); ++pos) {
            cout << *pos << '\n';
         }
         rows.resize(BATCH_SIZE); //ERROR
      }

This is clearly related to your Peer class which must not be default constructible or something like this. When reporting a bug, please provide a simple self-contained example reproducing the problem, not just some snippet of code.

Could you reread the error message once more?

It tells nothing related to my code. The problem is with soci::row!

And as you could also see my class Peer existed only in a function parameters, (now removed) and does not participate.

Sorry, I didn't notice/realize you used vector of rows. We need to make row movable to fix this.

[kuvaldini]

Yes. Thanks a lot for understanding and attention.
