［zz］安装mysql 获得 mysql.h 建立C接口

代码:

sudo apt-get install mysql-server mysql-client

代码:

sudo apt-get install libmysqlclient15-dev

代码:

#include <mysql.h>

代码:

gcc $(mysql_config --cflags) xxx.c -o xxx $(mysql_config --libs)

代码:

/* Simple C program that connects to MySQL Database server*/
#include <mysql.h>
#include <stdio.h>

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

   char *server = "localhost";
   char *user = "root";
   char *password = ""; /* 此处改成你的密码 */
   char *database = "mysql";

    conn = mysql_init(NULL);

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

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

    res = mysql_use_result(conn);

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

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