我博客的原文地址:
Perl 连接 Oracle 示例
http://blog.csdn.net/renfengjun/article/details/7967548
首先需要先下载3个模块
地址:
ftp://ftp.funet.fi/pub/languages/perl/CPAN/modules/by-module/DBI/
DBI-1.622.tar.gz
DBD-Oracle-1.50.tar.gz
Data-ShowTable-3.3.tar.gz (data目录中)
2.
安装[root@james-test oracle]# tar xzvf DBI-1.622.tar.gz
[root@james-test oracle]# tar xzvf DBD-Oracle-1.50.tar.gz
[root@james-test oracle]# tar xzvf Data-ShowTable-3.3.tar.gz
以下安装命令都使用的root用户
安装dbi
cd DBI-1.622
perl Makefile.PL
make
make install
安装showtable
cd Data-ShowTable-3.3
perl Makefile.PL
make
make install
安装dbd(需要先设置oracle_home)
cd DBD-Oracle-1.50
export ORACLE_HOME=/u01/apps/oracle/product/11gr2/db_1
perl Makefile.PL
make
make install
模块安装完毕
3.下面来两个示例example 1 简单连接数据库示例:
2.p :
#!/usr/bin/perl
#perl script used to connect to Oracle
use
strict;
use DBI;
my $tnsname="david";
my
$username="dexter";
my $password="xiaojun";
my
$dbh=DBI->connect("dbi:Oracle:$tnsname", $username, $password) or die "Cannot
conenct db: $DBI::errstr\n";
print "I have connected to the Oracle
database!\n";
$dbh->disconnect or warn "DB disconnect failed:
$DBI::errstr\n";
print "Disconnected from Oracle databae!\n";
[oracle@james-test ~]$ ./2.p I have
connected to the Oracle database!
Disconnected from Oracle databae!
example 2
连接数据库并且查询表示例:稍微修改一下
2.p:
#!/usr/bin/perl
#perl script used to connect to Oracle
use strict;
use
DBI;
my @row ;
my $tnsname="david";
my
$username="dexter";
my $password="xiaojun";
my
$dbh=DBI->connect("dbi:Oracle:$tnsname", $username, $password) or die "Cannot
conenct db: $DBI::errstr\n";
print "I have connected to the Oracle
database!\n";
my $sth=$dbh->prepare(" select * from emp_t "
);
$sth->execute();
while (@row = $sth->fetchrow_array()) {
print "row's @row\n"
}
$dbh->disconnect or warn "DB disconnect
failed: $DBI::errstr\n";
print "Disconnected from Oracle databae!\n";
[oracle@james-test ~]$ ./2.p
I have connected to the Oracle
database!

文中涉及的三个包我已经上传,详细看下面的地址:
安装dbd(需要先设置oracle_home),您的意思是,得先在linux上安装oracle客户端了,是吗?不然,oracle_home怎么指定啊.
对!
