Its similar to 'C' memory allocation. ie, the address of the pointer is
valid ONLY when the variable is in the system memory. I dont think you
can get same data by storing an address in the db and then retrieving
the address, unless you are trying to access some standard ports which
always exists and accessible. So its NOT advisable to store hash
reference in the database and cant guarentee to return the expected
data every time you read that memory. You can always assign
$my_new_hash_ref = 'HASH(0x91498b8)' and de-refer it as my
$my_new_hash = %$my_new_hash_ref;. But it may NOT return any value or
may return undef or may return some garbage or random value or a
de-reference error.<br>
<br>
Give a try and let us know. You may paste your code-snippet so that we
will get a better view of what you are trying to do and we may be able
to suggest something.<br>

you have the reference variable, can't you dereference it and use?<br>
For example, if $hashref is a hash reference, you can dereference it as

<div>Hi,<br>
<br>
Can you tell how can I map memory location to a variable. For
ex. I have a memory address for a hash reference say 0x23413. Is it
possible to access the hash using the memory address?<br>
