You could try this ...
1 select D.title, D.doc_num, D.version from junk D,
2 (
3 SELECT
4 A.doc_num doc_num
5 , MAX(A.version) version
6 from
7 junk A
8 , junk B
9 where
10 A.doc_num = B.doc_num
11 and A.title = B.title
12 and A.version >= B.version
13 group by
14 A.doc_num
15 ) C
16* where D.doc_num = C.doc_num and D.version = C.version
... bleh what a ugly mess.

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).

or How to display code and escape characters
are good places to start.
