centos7测试mysql c api

搭建环境测试环境

mysql> create database cusemysql;
Query OK, 1 row affected (0.00 sec)

mysql> use cusemysql;
Database changed

mysql> create table children(childno int not null unique,fname varchar(20),age int);
Query OK, 0 rows affected (0.00 sec)

mysql> insert into children values(5,"花儿",10);
Query OK, 1 row affected (0.00 sec)

mysql> select * from children;
+---------+-------+------+
| childno | fname | age  |
+---------+-------+------+
|       5 | 花儿  |   10 |
+---------+-------+------+
1 row in set (0.03 sec)

c测试代码，这里的用户名和密码都是root，不是的请修改

#include <stdio.h>
#include <stdlib.h>
#include "mysql/mysql.h" 
int main(int argc, char *argv[])
{
    MYSQL my_connection;

    int res;

    mysql_init(&my_connection);

    /*mysql_real_connect(&mysql,host,user,passwd,dbname,0,NULL,0) == NULL)*/
    if (mysql_real_connect(&my_connection, "localhost", "root", "root","cusemysql",0,NULL,CLIENT_FOUND_ROWS))
    {
            printf("Connection success\n");
        res = mysql_query(&my_connection, "insert into children values(11,'Anny',5)");

        if (!res)
        {    
            printf("Inserted %lu rows\n",(unsigned long)mysql_affected_rows(&my_connection));
        /*里头的函数返回受表中影响的行数*/
        }
        else
        {
        //分别打印出错误代码及详细信息
        fprintf(stderr, "Insert error %d: %s\n",mysql_errno(&my_connection),mysql_error(&my_connection));
        }
        mysql_close(&my_connection);
    }

    else
    {
        fprintf(stderr, "Connection failed\n");

        if (mysql_errno(&my_connection))
        {
                fprintf(stderr, "Connection error %d: %s\n",mysql_errno(&my_connection),mysql_error(&my_connection));
        }
    }
    return EXIT_SUCCESS;
}

编译、执行

[root@localhost test]# gcc -o insert insert.c -L /usr/lib64/mysql -lmysqlclient
[root@localhost test]# ./a.out
Connection success
Inserted 1 rows
