Qt連接Postgres數據庫

1Qt代碼如下

#include "datatools.h"
#include "ui_datatools.h"
#include <stdio.h>
#include <iostream>

using namespace std;
DataTools::DataTools(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::DataTools)
{
    ui->setupUi(this);
}

DataTools::~DataTools()
{
    delete ui;
}

void DataTools::on_pushButton_clicked()
{

    QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
    db.setHostName("192.168.0.201");
    db.setPort(5432);
    db.setDatabaseName("postgres");
    db.setUserName("postgres");
    db.setPassword("postgres");

    if(!db.open())
        ui->label->setText("Connection Failed!");
    else
        ui->label->setText("Connected");

}

2環境

1、postgresql-10.7-2-windows-X86.exe
2、Qt5.8.0-mingw
3、將Postgres安裝目錄下的動態庫拷貝到Qt編譯完成主程序的目錄下。
