一. 安裝DBI模塊
步驟1：
從TOOLS欄目中下載DBI.zip,下載完后用winzip解開到一個(gè)temp目錄,共有三個(gè)文件：
Readme
DBI.ppd
DBI.tar.gz
步驟2：
在DOS窗口下，temp目錄中運(yùn)行下面的DOS命令：
ppm install DBI.ppd
如果提示無(wú)效命令,可在perl/bin目錄下運(yùn)行
二. 安裝DBD-Mysql模塊
從軟件下載中下載DBD-Mysql.zip,安裝方法同一.
三. 準(zhǔn)備數(shù)據(jù)庫(kù)
啟動(dòng)mysql,首先創(chuàng)建一個(gè)數(shù)據(jù)庫(kù)mydata,然后創(chuàng)建一個(gè)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)
輸入些數(shù)據(jù):
mysql> insert into address values (
-> 1,'Nighthawk','nighthawk@163.net',92384092);
Query OK, 1 row affected (0.00 sec)
四. 下面用perl程序來(lái)插入若干記錄并做查詢.
use DBI;
#連接數(shù)據(jù)庫(kù)mydata
my $dbh = DBI->connect('DBI:mysql:mydata') or die "無(wú)法連接數(shù)據(jù)庫(kù): " . DBI->errstr;
print "插入若干記錄/n";
my $sth = $dbh->prepare(q{
INSERT INTO address (id, name,email,telephone) VALUES (?, ?, ?, ?)
}) });
print "輸入記錄,回車結(jié)束:";
while ($inputdata =<>) {
chop $inputdata;
last unless($inputdata);
my ($id, $name,$email, $tel) = split( /,/, $inputdata);
$sth->execute($id, $name, $email,$tel)
}
# $dbh->commit;
print "下面根據(jù)輸入的名字打印出EMAIL地址和電話/n";
my $sth = $dbh->prepare('SELECT * FROM address WHERE name=?')
or die $dbh->errstr;
print "請(qǐng)輸入姓名,回車結(jié)束:";
while ($inputname =<>) {
my @data;
chomp $inputname;
last unless($inputname);
$sth->execute($inputname) or die "錯(cuò)誤: " . $sth->errstr;
while (@data = $sth->fetchrow_array()) {
print "Email:$data[2]/t Telephone:$data[3]/n";
}
}
#斷開連接
$dbh->disconnect;
Nighthawk
