I think you are stuffed ;-) There is no way as it stands that DBD::ODBC can know these are not placeholders - the algorithm to search for placeholders is rather simple. We did introduce http://search.cpan.org/~mjevans/DBD-ODBC-1.17/ODBC.pm#odbc_ignore_named_placeholders for a similar reason and I guess we can do so again. If you want to report this as a problem you cannot find a way around on rt.cpan.org for DBD::ODBC I'll try and look into it for you.
