环境:Linux 2.6.32-28-generic
MySQL数据库安装
最懒的方法:
root@daoluan:~# apt-get install mysql-server
安装过程中会要求输入数据库密码。安装结束后,可以通过命令:
root@daoluan:~# mysql –u root –p
登录数据库。
实例操作
root@daoluan:~# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 66

mysql>
可以直接输入MySQL命令。
mysql> SHOW DATABASE;
mysql> create database library;
mysql> use library;
mysql> create table members (member_id int(11) not null auto_increment,fname varchar(50) not null,lname varchar(50) not null,tel varchar(15),email varchar(50) not null,primary key (member_id);
。。。。
MySQL Connector C
MySQL提供C接口的数据库连接器。最懒的方法:
root@daoluan:~# apt-get install libmysqlclient16-dev
16是版本号。安装完毕过后在所需要使用数据库功能的源码文件里头添加:
#include<mysql.h>
c语言MySQL连接示例
#include <stdio.h>
#include <mysql/mysql.h>
int main(int argc, char *argv[])
{
/* declare structures and variables */
MYSQL *conn_ptr;
MYSQL_ROW row;
MYSQL_FIELD * fields;
MYSQL_RES * result;
unsigned int i,num_fields;
/* initialize MySQL structure */
conn_ptr = mysql_init(NULL);
/* connect to database */
conn_ptr = mysql_real_connect(conn_ptr, "localhost", "root", "123456",
"library", 0, NULL, 0);
/* execute query */
mysql_query(conn_ptr,"select * from members");
/* get result set */
result = mysql_store_result(conn_ptr);
/* get the number of fields */
num_fields = mysql_num_fields(result);
/* print result set */
while((row = mysql_fetch_row(result)) != NULL)
{
for(i=0; i<num_fields; i++)
{
printf("%s ",row[i]!=NULL?row[i]:"NULL");
}// for
printf("\n");
}// while
/* clean up */
mysql_free_result(result);
mysql_close(conn_ptr);
return EXIT_SUCCESS;
}
将上面的代码存档为sample.c
root@daoluan:/code/sample_mysql# gcc -o sample sample.c -lmysqlclient
关于gcc的“-l”选项等诸多选项,http://www.cppblog.com/SEMAN/archive/2005/11/30/1440.html。执行 结果(数据库中已经预存了三条数据):
root@daoluan:/code/sample_mysql# ./sample
1 John Doe 1234567 jdoe@somewhere.com
2 aaa aaa 1234567 aaa@aaa.com
3 bbb bbb 1234567 bbb@bbb.com
root@daoluan:/code/sample_mysql#
