本文为大家分享了Eclipse中C++连接mysql数据库的具体代码，供大家参考，具体内容如下

MinGW的配置在C连mysql里已经提到，这里只说C++跟C配置不同的地方。

首先觉得C++比C方便多了，不用生成.a连接文件，直接使用.lib文件即可

导入.h文件所在目录到C++ Compiler中的includes

添加lib文件搜索

代码：


#include <winsock.h>
#include <iostream>
#include <string>
#include <mysql.h>
using namespace std;
int main() {
 MYSQL mydata;
 //初始化数据库
 mysql_library_init(0, NULL, NULL);
 mysql_init(&mydata);
 mysql_options(&mydata, MYSQL_SET_CHARSET_NAME, "gbk");
 //连接数据库
 if (NULL != mysql_real_connect(&mydata, "localhost", "root", "111111", "mysql", 3306, NULL, 0)) {
 cout << "mysql_real_connect() succeed" << endl;
 } else {
 cout << "mysql_real_connect() failed" << endl;
 return -1;
 }
 string sqlstr = "SELECT * FROM ME_MENU";
 MYSQL_RES *result = NULL;
 if (0 == mysql_query(&mydata, sqlstr.c_str())) {
 cout << "mysql_query() select data succeed" << endl;
 result = mysql_store_result(&mydata);
 int rowcount = mysql_num_rows(result);
 cout << "row count: " << rowcount << endl;
 unsigned int fieldcount = mysql_num_fields(result);
 MYSQL_FIELD *field = NULL;
 for (unsigned int i = 0; i < fieldcount; i++) {
 field = mysql_fetch_field_direct(result, i);
 cout << field->name << "\t\t";
 }
 cout << endl;
 MYSQL_ROW row = NULL;
 row = mysql_fetch_row(result);
 while (NULL != row) {
 for (unsigned int i = 0; i < fieldcount; i++) {
 cout << row[i] << "\t\t";
 }
 cout << endl;
 row = mysql_fetch_row(result);
 }
 } else {
 cout << "mysql_query() select data failed" << endl;
 mysql_close(&mydata);
 return -1;
 }
 mysql_free_result(result);
 mysql_close(&mydata);
 mysql_server_end();
 system("pause");
 return 0;
}
