152 views Asked by At

this is my database code



var con = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "",
  port: "889", 
});

con.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");
  con.query("CREATE DATABASE mydb", function (err, result) {
    if (err) throw err;
    console.log("Database created");
  });  
});

and this is the error I get when trying to run it in my terminal window

  if (err) throw err;
           ^

}

I tried looking up problems on the internet but I still don't know why I'm getting this error.

Like the person in the comments said:

var con = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "",
  port: "889", 
});

Is the wrong port number if you have other processes running on the same port SQL will not work usually people use:

var con = mysql.createConnection({
  host: "localhost",
  user: "root",
  password: "",
  port: "3306", 
});
