I was thinking about the OPs problem over dinner yesterday. I would imagine that the problem exists when you've got one handle open for read and you need to open another one with exactly the same statement. I wonder if prepare_cached could be changed to instead of just storing one handle, store an arrayref of them. When prepare_cached was called, it would go to the appropriate arrayref (via a hash lookup), and start iterating, calling $sth->{Active} on each until it finds one that isn't active, at which point it returns that one. If it fails to find an inactive one, it creates a new one and stores it. In the general case, you'd have only one stored. But, in cases like the OPs, it would just magically work. :)

The only easy day was yesterday

Are you posting in the right place? Check out Where do I post X? to know for sure.

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.
