要實現在VS上使用C語言操作MySQL數據庫。接下來看一下該怎么操作。

一、下載安裝MySQL

1、下載

下載：MySQL官網

我下載是 MySQL Installer 8.0.22 手動安裝版本。

點擊不需要注冊，即可下載。

2、安裝

選擇 Server only

3、include 和 lib

得到 include 和 lib

C:\Program Files\MySQL\MySQL Server 8.0\include

C:\Program Files\MySQL\MySQL Server 8.0\lib

二、navicat premium 安裝

下載安裝：navicat121_premium_cs

三、Visual studio 配置

1、放置 include 和 lib

點擊 在文件資源管理器中打開文件夾， 將上面得到的 include 和 lib 放置到該文件夾下。

lib里其實只需要 libmysql.lib，然后再將 libmysql.dll 放置到生成exe的文件夾下。

2、配置 include 和 lib

添加 屬性->C/C+±>常規->附加包含目錄->include

添加 屬性->鏈接器->常規->附加庫目錄->lib

四、C語言實現MySQL數據庫操作

終于到重點了。

1、在 Navicat Premium 新建一個數據庫

新建連接：

新建數據庫：

2、代碼實現

工程：MySQL 測試

#include <stdio.h> #include <string.h> #include <stdlib.h> #include <mysql.h> #pragma comment(lib, "libmysql.lib")MYSQL mysql;typedef struct {char Name[20];char Sex[20];int Age;int Sno;double Weight; }Student;void mysql_init_and_connect(void) {char value = 1;mysql_init(&mysql);mysql_options(&mysql, MYSQL_OPT_RECONNECT, (char*)&value);if (!mysql_real_connect(&mysql, "localhost", "root", "123456", "abc_123", 0, NULL, 0)){printf("\n mysql connect error! \n");}else{printf("\n mysql connect sucessfully! \n");}mysql_set_character_set(&mysql, "gbk"); }void mysql_create_table(MYSQL* mysql) {char res;char query[512] = { 0 };sprintf(query, "%s", "create table student ( \ 姓名 char(32) primary key, \ 性別 char(32), \ 年齡 int, \ 學號 int, \ 體重 double(32,3))");res = mysql_real_query(mysql, query, (unsigned long)(strlen(query) + 1));if (res){printf("\n Create Table Failed: %s \n", mysql_error(mysql));}else{printf("\n Create Table Sucessfully! \n");} }void mysql_insert(MYSQL* mysql, Student* Stu) {char res;char field[512] = { 0 };char message[512] = { 0 };char query[1024] = { 0 };sprintf(field, "%s", "insert into student values(%s)");sprintf(message, "\'%s\',\'%s\',%d,%d,%lf", Stu->Name,Stu->Sex,Stu->Age,Stu->Sno,Stu->Weight);sprintf(query, field, message);res = mysql_real_query(mysql, query, (unsigned long)(strlen(query)+1));if (res){printf("\n Insert Failed: %s \n", mysql_error(mysql));char str[512] = {0 };char Faillog[512] = { 0 };sprintf(Faillog, "%s", "Table 'abc_123.student' doesn't exist");sprintf(str, "%s", mysql_error(mysql));if (strcmp(str, Faillog) == 0){mysql_create_table(mysql);res = mysql_real_query(mysql, query, (unsigned long)(strlen(query) + 1));if (res){printf("\n Insert Failed: %s \n", mysql_error(mysql));}else{printf("\n Insert Sucessfully! \n");}}}else{printf("\n Insert Sucessfully! \n");} }void mysql_select(MYSQL* mysql) {char res;MYSQL_RES* mysql_res;MYSQL_ROW mysql_row;char query[512] = { 0 };char task[512] = { 0 };sprintf(query, "%s", "select * from student");res = mysql_real_query(mysql, query, (unsigned long)(strlen(query) + 1));if (res){printf("\n Select Failed: %s \n", mysql_error(mysql));}else{printf("\n Select Sucessfully! \n");}mysql_res = mysql_store_result(mysql);if (NULL == mysql_res){printf("\n Mysql Store Result Failed: %s \n", mysql_error(mysql));}else{while (mysql_row = mysql_fetch_row(mysql_res)){//for (res = 1;res < mysql_num_fields(res);res++)//{// printf("%s", mysql_row[res]);//}printf("%s\t", mysql_row[0]);printf("%s\t", mysql_row[1]);printf("%d\t", atoi(mysql_row[2]));printf("%d\t", atoi(mysql_row[3]));printf("%lf\n", atof(mysql_row[4]));}mysql_free_result(mysql_res);} }int main(void) {Student Stu;strcpy(Stu.Name, "小明");strcpy(Stu.Sex, "男");Stu.Age = 18;Stu.Sno = 25;Stu.Weight = 62.5;mysql_init_and_connect();mysql_insert(&mysql, &Stu);mysql_select(&mysql);getchar();return 0; }

3、測試結果

五、MySQL學習

現在該講一下什么是MySQL了，上面這些MySQL接口又是怎么用的。
