Database Error

[theCrazyCrap]

HI, I'm creating a RPG game on qt quick with a save game feature. In order for me to do that is to have a database to store in which level the player have finished. But when I am trying to run the program. It has an error "cannot find database" or reference error. Please help me and thank you in advance! Here is my code.

Database.js

@function getGameBase(){
return openDatabaseSync("gameBase", "1.0", "StorageDatabase", 50);
}

function initialize() {
var db = getGamebase();
db.transaction(
function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS game(gameNum NUMBER UNIQUE,money NUMBER,str NUMBER,int NUMBER,def NUMBER,level NUMBER)');

        //initialize start up value
                for(i=0; i <=3; i++ )
                {
                    tx.executeSql('INSERT INTO game VALUES (?, 100,5,3,5,0)', [i])
                }

            });

}

function getMoney(gameIter){
var db = getGameBase();

db.transaction(function(tx){
                   var rs = tx.executeSql('SELECT money FROM game WHERE gameNum=?;', [gameIter])}
                   )
return rs

}

function getLevel(gameIter){
var db = getGameBase();

db.transaction(function(tx){
                   var rs = tx.executeSql('SELECT level FROM game WHERE gameNum=?;', [gameIter])}
                   )
return rs

}
