apache cordova using sqlite can't wait to return

     function outDb(outData) {
         var temp;
         var db = window.sqlitePlugin.openDatabase({ name: "test" });
         db.executeSql("SELECT " + outData + " FROM test", [], function (res) {
             switch (outData) {
                       case "goal": temp = res.rows.item(0).GOAL;
                     break;
                 case "curDate":  temp = res.rows.item(0).CURDATE;
                     break;
                 case "Day1":  temp = res.rows.item(0).DAY1;
                     break;
                 case "Day2":  temp = res.rows.item(0).DAY2;
                     break;
                 case "Day3":  temp = res.rows.item(0).DAY3;
                     break;
                 default: temp = "is default";
             }
         });
         return temp;
     }

I want to save data into myData;

var myData = outDb("goal");

but it is not working. because return faster than variable save.

What can I do?
