1.C连接mysql的方法:C ,C ++ ,ODBC ,java ,Net ...,这里看C的连接,首先进入mysql驱动官网下载connector/c http://dev.mysql.com/downloads/connector/ 选择C版下载 2.C 在vc 6环境下连接mysql :下面贴出源码(看别人写的,以此作参考) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 ...
1、安装好mysql 2、要实现C连接数据库,需要安装数据库连接器(即MySQL Connector/C) MySQL Connector/C是一个C语言的client库,这个库是为了实现client/server通信的。 MySQL Connector/C是一个独立的替换为装有mysql server的mysql client库 3、要安装MySQL Connector/C,需要安装cmake。 下载包:cmake-2.6.4.tar....
MYSQL *conn; conn = mysql_init(NULL); 连接MySQL数据库:使用以下语句连接到MySQL数据库: 代码语言:txt 复制 if (mysql_real_connect(conn, "localhost", "username", "password", "database", port, NULL, 0) == NULL) { fprintf(stderr, "Failed to connect to database: Error: %s\n", mysql_...
