eclipse中C++連接mysql數據庫

MinGW的配置在C連mysql裏已經提到，這裏只說C++跟C配置不同的地方。

首先覺得C++比C方便多了，不用生成.a連接文件，直接使用.lib文件即可

導入.h文件所在目錄到C++ Compiler中的includes

添加lib文件搜索

#include <winsock.h>
#include <iostream>
#include <string>
#include <mysql.h>
using namespace std;

int main() {
	MYSQL mydata;
	//初始化數據庫
	mysql_library_init(0, NULL, NULL);
	mysql_init(&mydata);
	mysql_options(&mydata, MYSQL_SET_CHARSET_NAME, "gbk");
	//連接數據庫
	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;
}
