里面的函數(shù)做的差很多，粗略能用，簡單分享一下

    //新建數(shù)據(jù)庫
    void l_new_sqlite(QString connect_name,QString sqlite_type,QString sqlite_name,QString user_name,QString user_password);
    //新建表
    void l_new_table(QString table_name);
    //打開數(shù)據(jù)庫
    bool l_open_sqlite(QSqlDatabase db);
    //關(guān)閉數(shù)據(jù)庫
    void l_close_sqlite(QSqlDatabase db);
    //插入數(shù)據(jù)
    void l_insert_data(QString table_name,qint8 number,QString time,qreal first_floor_value,qreal sencond_floor_value,qreal third_floor_value,qreal forth_floor_value );
    //查詢數(shù)據(jù)
    void l_search_table(QString table_name,QString str);
    //更新數(shù)據(jù),修改數(shù)據(jù)
    void l_refesh_data(QString table_name);
