我在perl中使用模块DBD::Oracle
将xml内容插入到oracle 11g实例中。在我的示例集中插入一些文档时,脚本会在模块返回Unsupported named object type for bind parameter
时失败。我想处理这个错误并使循环迭代继续。
以下是我的代码,
use strict;
use warnings;
use DBI;
use DBD::Oracle qw(:ora_session_modes);
use DBD::Oracle qw(:ora_types);
die("USAGE: $0 <input_directory>") unless ($#ARGV == 0);
my $directory=$ARGV[0];
my $dbh = DBI->connect('dbi:Oraclle:dbname',"username", "pass");
my $SQL;
opendir(IMD, $directory) || die ("Cannot open directory");
my @listOfFiles= readdir(IMD);
closedir(IMD);
my $xmltype_string;
my $xml;
my $i = 1;
foreach my $file(@listOfFiles)
{
unless($file eq '.' or $file eq '..')
{
print "inserting File no. $i \t $file .... \n";
{
local $/=undef;
open (FILE , "<" , "$directory/$file" );
$xml=<FILE>;
close (FILE);
}
$SQL="insert into sampleTable values ( :ind, :xml)";
my $sth =$dbh-> prepare($SQL);
$sth->bind_param(":xml" , $xml , { ora_type => ORA_XMLTYPE});
$sth->bind_param(":ind" , $i);
$sth-> execute();
$i++;
}
}
我在bind param中收到错误。

错误处理通常通过Try::Tiny
模块完成:
use Try::Tiny;
try {
something_that_could_die();
}
catch {
handle_error($_);
}
finally {
do_something_either_way();
}; # ← trailing semicolon not optional.
catch
和finally
都是可选的。
