Hi all,
I am looking for a "fetch" function to fetch "n" number of records at a time
in Perl DBI !
"fetchrow_hashref" fetches one row at a time whereas "fetchall_hashref"
fetches all the rows at a time.
The requirement is to get 100 records at a time (in array or hash) before
printing it into th
I guess thats a task you can achieve with the correct sql-statement.
Have a look at http://www.adp-gmbh.ch/ora/sql/examples/first_rows.html.
How you can implement an sql-query that give you the results you need,
depends on how the data in your db looks like. If you have a fixed index number

If $max_rows is defined and greater than or equal to zero then it is
used
to limit the number of rows fetched before returning.
fetchall_arrayref() can then be called again to fe

You mean GnuPG::Interface ? (Perl is quantity-sensitive :-)

there is a LIMIT option for the SELECT statement that will return the
number of records you desire.
$sth = $dbh->prepare("select from LIMIT ");
$sth->execute();
while ($vars ...) = $sth->fetchrow_array())
{
}

what may cause perl to give the following command line output

Hi Oliver,
You have to show more of the source code -- but it sounds like you've
declared $form with "my" within a function/subroutine and it is not
visible outside the function? Could that be the problem?

I understand a $stmt->execute($sql) will return me the recordset and I
can fetch the records using fetchrow_hashref and other methods

I have a weird problem with our Lotus Notes IMAP server -- certain spam
messages cause our email clients to not download that message, nor any
subsequent ones.
So I thought I'd write a perl script that I could run that would go onto the
IMAP server and look for messages with the specific traits
Hello Ray,
Thanks for your response. I could already solve the problem. It was caused by
a syntax error in a different line within the same sub.:-) I read my source
code over and over and finally find the error.

There are online RegEx-Utilities that helps you building regex.
There are some modul with many common regex to steal from or just import.

There are a LOT of Moduls at cpan to talk with IMAP-Accounts & Servers,

Hi Amit,
Generally, what Dan says is correct, but his suggestion isn't *the*
answer that will work for everyone. He is correct about the size of a
data column and the problem of retrieving all of the data. Also, an
index is usually build on the primary key, so the first fetch should be
