Python Mysql数据库操作 Perl操作Mysql数据库

首先下载 MySQLdb
#encoding=GBK
import MySQLdb
#import sys
#
#reload(sys)
#sys.setdefaultencoding('utf-8')
print 'Connection ...'
host='192.168.1.77'
user='root'
passwd='123456'
db='test'
conn = MySQLdb.connect(host,user,passwd,db,charset='gbk')
print 'Connection success'
cursor = conn.cursor()
#query = "insert into test(id,name) values(%s , %s)"
#param = ("1","汉字")
#cursor.execute(query,param)
#
#conn.commit()
cursor.execute('select * from test')
rows = cursor.fetchall()
for row in rows:
print row[1]
cursor.close()
conn.close()
Perl操作Mysql数据库 网上的比较详细的方法
一. 安装DBI模块
步骤1：
从TOOLS栏目中下载DBI.zip,下载完后用winzip解开到一个temp目录,共有三个文件：
Readme
DBI.ppd
DBI.tar.gz
步骤2：
在DOS窗口下，temp目录中运行下面的DOS命令：
ppm install DBI.ppd
如果提示无效命令,可在perl/bin目录下运行
二. 安装DBD-Mysql模块
从软件下载中下载DBD-Mysql.zip,安装方法同一.
三. 准备数据库
启动mysql,首先创建一个数据库mydata,然后创建一个表address
mysql> create database mydata;
Query OK, 1 row affected (0.00 sec)
mysql> use mydata;
Database changed
mysql> create table address (
-> id int(5) not null,
-> name varchar(40) not null,
-> email varchar(50) not null,
-> telephone int(12) null);
Query OK, 0 rows affected (0.05 sec)
输入些数据:
mysql> insert into address values (
-> 1,'Nighthawk','[email protected]',92384092);
Query OK, 1 row affected (0.00 sec)
四. 下面用perl程序来插入若干记录并做查询.
use DBI;
#连接数据库mydata
my $dbh = DBI->connect('DBI:mysql:mydata') or die "无法连接数据库: " . DBI->errstr;
print "插入若干记录\n";
my $sth = $dbh->prepare(q{
INSERT INTO address (id, name,email,telephone) VALUES (?, ?, ?, ?)
}) });
print "输入记录,回车结束:";
while ($inputdata =<>) {
chop $inputdata;
last unless($inputdata);
my ($id, $name,$email, $tel) = split( /,/, $inputdata);
$sth->execute($id, $name, $email,$tel)
}
# $dbh->commit;
print "下面根据输入的名字打印出EMAIL地址和电话\n";
my $sth = $dbh->prepare('SELECT * FROM address WHERE name=?')
or die $dbh->errstr;
print "请输入姓名,回车结束:";
while ($inputname =<>) {
my @data;
chomp $inputname;
last unless($inputname);
$sth->execute($inputname) or die "错误: " . $sth->errstr;
while (@data = $sth->fetchrow_array()) {
print "Email:$data[2]\t Telephone:$data[3]\n";
}
}
#断开连接
$dbh->disconnect;
Nighthawk
