1. 创建

	QSqlQuery sql_query = QSqlQuery(m_db);
	QString sql = QString("CREATE TABLE logger(m_id INTEGER PRIMARY KEY AUTOINCREMENT, m_time TEXT);");
	sql_query.exec(sql);

2. 添加

	QSqlQuery sql_query = QSqlQuery(m_db);
    sql_query.prepare("INSERT INTO logger (m_time) VALUES(?);");
    sql_query.addBindValue("2024-01-01 08:00:00");
    sql_query.exec();
