using SQL db instead of playerprefs (playerlocation)

Ive created a really simple SQL db on a server with a few tables and populated it as above, what would be the most efficient way to retrieve these values and call them when a player logs in to set the player location and scene to load?

Remote SQL Server. Windows Standalone Client.

this is the script im using as login atm i know its a bit raw and missing alot but im working with a few different parts at the sametime just to build a framework

 using UnityEngine;
 using System;
 using System.Collections;            // for using hash tables
 using System.Security.Permissions;    // for getting the socket policy
 using SmartFoxClientAPI;            // to setup SmartFox connection
 using SmartFoxClientAPI.Data;        // necessary to access the room resource
 
 public class gui_Login : MonoBehaviour {
     
     // smartFox variables
     private SmartFoxClient smartFox;
     private string serverIP = "192.168.0.101";
     private int serverPort = 9339;                // default = 9339
     public string zone = "city";
     public bool debug = true;
     
     // variables used in script
     private string statusMessage = "";
     private string username = "";

         Application.runInBackground = true;     // Let the application be running while the window is not active.
         
         // Create SmartFox connection if not already available
         if ( SmartFox.IsInitialized() ) {
             Debug.Log("SmartFox is already initialized, reusing connection");
