ubuntu下c调用mysql的简单例子

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

int main()
{
MYSQL * conn;
MYSQL_RES * res;
MYSQL_ROW row;
char * server = "localhost";
char * user = "root";
char * password = "19890207";
char * database = "bit";
conn = mysql_init(NULL);

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

if (mysql_query(conn, "select * from users"))
{
fprintf(stderr, "%s\n", mysql_error(conn));
exit(1);
}

res = mysql_use_result(conn);

printf("the data of users\n");

while ((row = mysql_fetch_row(res)) != NULL)
printf("%s\n", row[0]);

mysql_free_result(res);
mysql_close(conn);
return 0;
}

ps：改代码运行需要安装了

mysql-client

　　libmysqlclient15-dev

　　mysql-server:

　　gcc, make and other development libs

编译命令如下：

$ gcc -o output-file $(mysql_config --cflags) mysql-c-api.c $(mysql_config --libs)

对应的数据库名称和密码修改为自己对应的即可
