搭建環境測試環境

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,"花兒",10);
Query OK, 1 row affected (0.00 sec)

mysql> select * from children;
+---------+-------+------+
 

| childno | fname | age  |
+---------+-------+------+
|       5 | 花兒  |   10 |
+---------+-------+------+
1 row in set (0.03 sec)

c測試程式碼，這裡的使用者名稱和密碼都是root，不是的請修改

#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));
        /*裡頭的函式返回受表中影響的行數*/
        }
        else
        {
        //分別打印出錯誤程式碼及詳細資訊
        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;
}

編譯、執行

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