I want to be able to list the field names and their
description (varchar, number, date, etc) using Perl DBI.
But I cant do it! Is there a way to do it?
This is what I am trying to do right now:
$dbh = Call our algorithm that connects us to the DB.
if (!$dbh)
{
print "Cannot connect to database: $DBI::errstr\n";
}
$sth = $dbh->prepare(q{desc userinfo});
$sth->execute();
$dbh->disconnect;
exit(1);
This is what I get:
DBD::Oracle::db prepare failed: ORA-00900: invalid SQL statement (DBD: error possibly near <*> indicator at char 1 in '<*>desc userinfo') at ./get-userinfo-fields.pl line 38.
Can't call method "execute" on an undefined value at ./get-userinfo-fields.pl line 39.
Is there also a way in which I can get the field names in
a SELECT clause? Is there a reserved word like, for example, if I wanted to search for all the tables in a DB, I would do "select table_name from all_tables"?
Thanks!
Robert

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).
