You should use the $dbh->table_info(...) method.
It will return a statement handle, that iterates the table(s) you define, thus alloowing easy check whether a table exists.
Your call would be something like $sth=$dbh->table_info("", $schema, $table_name, "TABLE");
if ($sth->fetch) {
# table exists
} else {
# doesn't
}
This will work on all DBD's (as soon as the authors have implemented the table_info method - most have). If yours doesn't work, then please contact your DBD-author and help him get it done.

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).
