Of your three, #2 looks best to me. It's a decent heuristic.
#3 is, I think, actually impossible in general. Consider:
my $v1 = 'field3';
my $v2 = 'value';
sql_interp('SELECT * FROM table WHERE field1 = ', $v1, ' AND field2 =
+', $v2)
#3 would presumably make this be equivalent to field1 = 'field3' AND field2 = 'value', but the programmer might well have intended it to be field1 = field3 AND field2 = 'value', at which point the DWIMmery would merely have resulted in a perplexing bug. There's no way to determine which of the two was intended (let alone the other possible permutations), so it's better just to require the programmer to be explicit.

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).
