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;

}
