Eclipse中C++连接mysql数据库

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;
}
