I have now faced the same problem with different context - "show table" on Teradata via ODBC call was failing with the error described here.
This is the code for sub that returns the table definition correctly, when given the database handle ($dbh) and "show table statement" ($sql).
I am writing this here for any unfortunate soul, which could face the same issue as me in the future - as well as for my future self.
Thanks to all who showed me kindness in the past, and helped me solve the problem.
sub _long_show ( $dbh, $sql ) {
my $sth = $dbh->prepare($sql);
$sth->execute();
$sth->bind_col(1, undef, {TreatAsLOB=>1});
my $data;
my $retval = "";
while($sth->fetch) {
while (my $retrieved = $sth->odbc_lob_read(1, \my $data, 65535
+)) {
$retval .= $data;
}
}
return $retval . "\n";
}

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).
