- VS2015 調用mysql的demo筆記
- 整理了下網上的內容,這裏記一下
1.創建任意終端程序;
2.指定包含頭文件路徑:
Project->properties->C/C++->Additional Include Directories->(這裏指定mysql各種頭文件的目錄,我的是mysql文件夾裏的include)
3.指定lib路徑:
Project->properties->Linker->General->Additional Library Directories->(這裏是libmysql.lib所在路徑,我的是在lib裏)
4.添加lib:
Project->properties->Linker->Input->Additional Dependencies->增加libmysql.lib
5.修改配置:
Build->Configuration Manager->Active solution platform->x64
(爲了避免模塊計算機類型x64與目標計算機類型x86衝突
)
6.將libmysql.dll放到新建的終端程序源代碼下;
以下爲測試代碼:
// ConsoleApplication1_mysql_01.cpp : Defines the entry point for the console application.
//
#pragma comment(lib,"libmysql.lib")
#pragma comment(lib, "ws2_32.lib")
#include "stdafx.h"
#include <winsock.h>
#include "mysql.h"
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <mysql.h>
void sqlselect(MYSQL *mysql, char *command)
{
int flag = mysql_real_query(mysql, command, strlen(command));
if (flag)
{
printf("Select error:%d, %s\n", mysql_errno(mysql), mysql_error(mysql));
return;
}
MYSQL_RES *res = mysql_store_result(mysql); //讀取將查詢結果
MYSQL_FIELD *field = mysql_fetch_fields(res); //獲取所有列名
int field_count = mysql_field_count(mysql); //獲取列數
//輸出所有列名
for (int i = 0; i < field_count; i++)
{
printf("%s\t", field[i].name);
}
printf("\n");
//遍歷輸出每一行數據
MYSQL_ROW row;
while (row = mysql_fetch_row(res))
{
for (int i = 0; i < field_count; i++)
{
printf("%s\t", row[i]);
}
printf("\n");
}
}
int main()
{
//初始化MySQL連接句柄
MYSQL *mysql = NULL;
mysql = mysql_init((MYSQL *)0);
mysql_real_connect
(
mysql,
"localhost", //數據庫地址
"root", //數據庫用戶名
"123456", //數據庫密碼
"demo", //數據庫名稱
0, //數據庫端口,0表示默認端口(即3306)
NULL, //如果unix_socket不是NULL,字符串指定套接字或應該被使用的命名管道。注意host參數決定連接的類型
0 //通常是0
);
if (!mysql) //連接失敗
{
printf("Connection error:%d, %s\n", mysql_errno(mysql), mysql_error(mysql));
}
else
{
printf("hello world\n");
}
char *command = "select * from student"; //查詢指令
sqlselect(mysql, command); //查詢數據
mysql_close(mysql); //關閉連接
system("pause");
return 0;
return 0;
}
