- 介绍:SQLITE 是一个轻型的数据库系统,他不需要安装和配置,保存在本地,后缀名以db结尾,支持SQL语言,可以用SQLite Export 工具来查看数据库文件。
- QT中使用:
void MainWindow::on_pushButton_clicked() { QStringList strlist = QSqlDatabase::drivers(); for(int i = 0; i < strlist.size();i++) { qDebug()<<strlist.at(i); } QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE"); db.setDatabaseName("mytest.db"); //在工程目录新建一个mytest.db的文件 if(!db.open()) { qDebug()<<"open fail!"; return ; } QSqlQuery query(db); bool bsuccess = query.exec("create table person (id int primary key, " "firstname varchar(20), lastname varchar(20))"); //创建一个表 query.exec("insert into person values(101, 'Danny', 'Young')"); query.exec("insert into person values(102, 'Christine', 'Holand')"); query.exec("insert into person values(103, 'Lars', 'Gordon')"); query.exec("insert into person values(104, 'Roberto', 'Robitaille')"); query.exec("insert into person values(105, 'Maria', 'Papadopoulos')"); if(!bsuccess) { qDebug()<< "table is error"; } else { qDebug()<<"table is ok"; } QSqlTableModel *model = new QSqlTableModel; model->setTable("person"); model->setEditStrategy(QSqlTableModel::OnManualSubmit); model->select(); ui->tableView->setModel(model); ui->tableView->show(); }
