我有一个mysql脚本，我的数据库，我想导入这个数据库到我的android应用程序使用该脚本，当我执行这个代码它的作品（我不知道）´没有任何异常或错误），但当我试图从数据库获取信息时，它没有´不起作用。

private static String DB_PATH = "/data/data/com.example.importDB/databases/";
    private static String DB_NAME = "mydb.sql";
    private SQLiteDatabase myDataBase;
    private final Context myContext;
    public DataBaseHelper(Context context) {
        super(context, DB_NAME, null, 1);
        this.myContext = context;
    }
    public void createDataBase() throws IOException {
        boolean dbExist = checkDataBase();
        if(dbExist){
            //do nothing - database already exist
        }else{
            this.getReadableDatabase();
            try {
                copyDataBase();
            } catch (IOException e) {
                throw new Error("Error copying database");
            }
        }
    }
    private boolean checkDataBase(){
        SQLiteDatabase checkDB = null;
        try{
            String myPath = DB_PATH + DB_NAME;
            checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
        }catch(SQLiteException e){
            //database does't exist yet.
        }
        if(checkDB != null){
            checkDB.close();
        }
        return checkDB != null ? true : false;
    }
    private void copyDataBase() throws IOException{
        InputStream myInput = myContext.getResources().openRawResource(R.raw.mydb);
        String outFileName = DB_PATH + DB_NAME;
        OutputStream myOutput = new FileOutputStream(outFileName);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = myInput.read(buffer))>0){
            myOutput.write(buffer, 0, length);
        }
        myOutput.flush();
        myOutput.close();
        myInput.close();
    }
    public void openDataBase() throws SQLException {
        String myPath = DB_PATH + DB_NAME;
        myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
    }
    @Override
    public synchronized void close() {
        if(myDataBase != null)
            myDataBase.close();
        super.close();
    }

我的“mydb.sql”在res/raw文件夹中
这是mysql脚本：
