I am currently trying to pass a hash by reference to a subroutine. The hash is generated by the following query :
my $existing_users = $dbh->selectall_hashref("SELECT `UserName`, `
+LastAccessDate`, `Ignore` FROM $status_database.`Status`",1);
and prints out the following
'user1' => {
'UserName' => 'user1',
'Ignore' => 'N',
'LastAccessDate' => '0000-00-00'
},
'user2' => {
'UserName' => 'user2',
'Ignore' => 'N',
'LastAccessDate' => '0000-00-00'
},
This wasn't a problem when I was using the hash globally but now I am trying to pass it to subroutines to organize the code a little better. I am sure this is something simple that I am just over looking. Doing the following simply prints out a number
send_to_sub(%{$existing_users});
sub send_to_sub{
my $existing_users = @_;
print Dumper(\$existing_users);
exit;
}
Help would be appreciated

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
