Sqlite是一个小巧的嵌入式关系型数据库，几乎可以嵌入所有编程语言，特别是C，C++，PHP，Perl等。这里就介绍如何用Perl连接并操作Sqlite数据库。

use DBI; # perl用以操作sqlite的模块，有这一个模块就足够了

use strict; # 初学必须加上这一句，以严格要求语句的撰写

use warnings;

main:

{

my $dbargs = {AutoCommit => 0, #使用事件

PrintError => 1};

# 连接到数据库

my $dbh = DBI->connect("dbi:SQLite:dbname=test.db","","",$dbargs);

# 创建表

$dbh->do("create table test(id int primary key, age, name)");

# 插入数据

$dbh->do("insert into test values(Null,'34','Liu Qiang'");

#更新数据

$dbh->do("update test set age='33' where name='Liu Qiang'");

#删除数据

$dbh->do("delete from test where name='Liu Qiang'");

#查询数据

my $sql = "SELECT * FROM test";

my $dbconn = $dbh->prepare($sql);

$dbconn->execute();

my (@row_ary,$cc,$bb,$dd);

while (@row_ary = $dbconn->fetchrow_array ){

my($cc,$bb,$dd) = @row_ary;

print "表Test的内容为\n";

print "\t@row_ary\n";

}

#删除表

#$dbh->do("drop table test");

#清空表，表结构还存在

$dbh->do("delete from test");

if ($dbh->err()) { die "$DBI::errstr\n"; } #连接错误提示

$dbh->commit();

$dbh->disconnect(); #断开数据库链接

}
