get data as JSON sql

testJsonSql.js

const whatIWant = {
  username: 'u.username',
  uid: 'u.id',
  network: 'p.network'
};

let testJsonSql = whatIwant => {
  let ret = '"{",';
  for (k in whatIwant) {
    ret += ` '"',   "${k}" , '":"',  ${whatIwant[k]},  '",'`;
  }
  ret = ret.substr(0, ret.length - 2) + `'"}"`;
  console.log('ret', ret);
  return ret;
};

// Usage :

// `GROUP_CONCAT(DISTINCT ${testJsonSql(   whatIWant  )} SEPARATOR "∆∆∆") as lesBails`


// lesBails.split('∆∆∆').map(e => JSON.parse(e))
