仅从数据库中获取唯一值作为 json 响应

Question

I have a database and understand in sql I can get unique values via: Select DISTINCT name, industry from database; however when I access it via local host and look at the json response i get duplicate values from different times.

code in VSCODE:

  req.db.from('database').select("name","symbol")
    .then((rows) => {
      res.json({ "Error": false, "Message": "Success", "Database": rows })
    })
    .catch((err) => {
      console.log(err);
      res.json({ "Error": true, "Message": "Error in MYSQL query" })
    })
});

what do I need to alter to only receive the name and symbol of each response once and not for every single entry of that object in the database?
