代码如下:
main.cpp函数
#include "mainwindow.h"

#include <QDebug>
int main(int argc, char *argv[])
{

db.setDatabaseName("/tmp/my.db");
if (!db.open())
{
qDebug()<<"open database failed ---"<<db.lastError().text()<<"/n";
return -1;
}
QSqlQuery query;
bool ok = query.exec("CREATE TABLE IF NOT EXISTS people (id INTEGER PRIMARY KEY AUTOINCREMENT,"
"name VARCHAR(20) NOT NULL,"
"age INTEGER NULL)");
if (ok)
{
qDebug()<<"ceate table partition success/n";
}
else
{
qDebug()<<"ceate table partition failed/n";
}
for (int i = 0; i< 3; ++i)
{
query.prepare("INSERT INTO people (id, name, age) VALUES (:id, :name, :age)");
query.bindValue(":name", QString("smith_%1").arg(i+1));
query.bindValue(":age", 20+i*5);
query.exec();
}
query.exec("SELECT id, name, age FROM people");
while (query.next())
{
qDebug()<<"people("<<query.value(0).toInt()<<") name:"<<query.value(1).toString()<<" age:"<<query.value(2).toInt();
}
MainWindow w;
w.show();
return a.exec();
