mysql practice

setup environment:
https://www.digitalocean.com/community/tutorials/a-basic-mysql-tutorial
construct database xxx
and set table potluck

#include <mysql/mysql.h>
#include <stdio.h>
#include <stdlib.h>

int main() {
    MYSQL *conn;
    MYSQL_RES *res;
    MYSQL_ROW row;

    char *server = "localhost";
    char *user = "root";
    char *password = "******";
    char *database = "test";

    conn = mysql_init(NULL);

    /* Connect to database */
    if (!mysql_real_connect(conn, server,
        user, password, database, 0, NULL, 0)) {
    fprintf(stderr, "%s
", mysql_error(conn));
    exit(1);
    }

    /* send SQL query */
    if (mysql_query(conn, "show tables")) {
    fprintf(stderr, "%s
", mysql_error(conn));
    exit(1);
    }

    res = mysql_use_result(conn);

    /* output table name */
    printf("MySQL Tables in mysql database:
");
    while ((row = mysql_fetch_row(res)) != NULL)
    printf("%s 
", row[0]);

    /* close connection */
    mysql_free_result(res);
    mysql_close(conn);

    return 0;
}
