I don't know a heck of a lot about MySQL, but according to gmax's excellent New twist for DBD::mysql, DBD::mysql currently does emulate placeholders but in such a way as to preserve security. I'd suggest reading his node for further details.

    It doesn't seem to be totally secure:
    As for LIMIT ?,?. The reason why it was not supported since 2.9002 is that it allowed for sql injection attacks, and it is not trivial to fix, in fact, I *just* scanned over Patrick's code and found a bug in the LIMIT handling code
    as can be read in Re: New twist for DBD::mysql.
