Re: Storable retrieve

How are you storing the information to begin with? Do you mean you're using the Storable module to serialize the information first? If so, then I can't see why (or how) you'd then insert that into a DB_File. If on the other hand you're merely inserting a normal hash into a DB_File, then (from the documentation), use tie to load the data into a hash and merely foreach as normal over the keys:

tie %hash,  'DB_File', [$filename, $flags, $mode, $DB_HASH];
foreach (keys %hash) { ... }

Alternatively, after tie'ing the hash, you can use:

$hash->get($key, $value [, $flags]);

Basically i want to store a hash directly in to an MLDBM I thgt using Storable will be faster But it is as the same speed as Data::Dumper hence if u can suggest something Thanks	[reply]
