[英]Insert data into mysql table from c++ program using OTL library
I want to insert int
and string
value into mysql table from c++ program. 我想将
int
和string
值从c ++程序插入mysql表。
for (std::map < int, std::vector < std::string > >::iterator hit = three_highest.begin(); hit != three_highest.end(); ++hit) {
//std::cout << hit->first << ":";
for (std::vector < std::string >::iterator vit = (*hit).second.begin(); vit != (*hit).second.end(); vit++) {
std::cout << hit->first << ":";
std::cout << *vit << "\n";
I want to insert hit->first
and *vit
. 我想插入
hit->first
和*vit
。
I saw example here : OTL Example for mysql . 我在这里看到了示例: OTL mysql示例 。 Will it work for me?
对我有用吗?
And how to set OTL environment in my system? 以及如何在系统中设置OTL环境? Do I need to install it or what?
我需要安装它还是什么?
include <mysql.h>
Which I could not find in my system. include <mysql.h>
这在我的系统中找不到。 What environment it using? I am using Linux - Ubuntu environment. 我正在使用Linux-Ubuntu环境。
Here I got how to connect c++ with mysql: 在这里,我了解了如何将c ++与mysql连接:
first compiled the c++ connector library from source but after a while I thought maybe I did something wrong so I then just used apt to get it with: 首先从源代码编译了c ++连接器库,但过了一会儿我以为我做错了什么,所以我就使用apt来获取它:
sudo apt-get install libmysqlcppconn-dev
So I have now had this problem for a week now and I became very frustrated with it as well. 所以我现在已经有一个星期的问题了,对此我也感到非常沮丧。 I just now was able to finally build a program that does nothing except login to mysql and I literally squealed with joy.
我现在终于能够构建一个程序,除了登录mysql以外什么都不做,而我确实高兴极了。 Here is what I have and I hope it helps.
这是我所拥有的,希望对您有所帮助。
I first compiled the c++ connector library from source but after a while I thought maybe I did something wrong so I then just used apt to get it with: 我首先从源代码编译了c ++连接器库,但过了一会儿我以为可能是我做错了,所以我只用apt来获取它:
sudo apt-get install libmysqlcppconn-dev 须藤apt-get install libmysqlcppconn-dev
And here is my simple tester source file "tester.cpp" 这是我简单的测试器源文件“ tester.cpp”
#include <stdlib.h>
#include <iostream>
#include <mysql_connection.h>
#include <driver.h>
#include <exception.h>
#include <resultset.h>
#include <statement.h>
using namespace sql;
int main(void){
sql::Driver *driver;
sql::Connection *con;
driver = get_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306","root","YOURPASSWORD");
return 0;
}
And finally g++ compile command: 最后是g ++编译命令:
sudo g++ -Wall -I/usr/include/cppconn -o testapp tester.cpp -L/usr/lib -lmysqlcppconn
