Unless there is some magic *other* than importing :sql_types and using bind_param on my $statement_handle... no. Is this what you refer to?

If I understand at all what is going on, it is having the placeholder for that field when the $sth is 'prepared' -- that is the problem. It appears the solution is the convert statement must be _in_ the SQL when the SQL is parsed by the (driver? server?) and the statement handle is created.

So, can I use DBIx::Class to get that 'convert' function mapped onto an accessor when I create the files for the schema? Or can I make a custom resultset (or something) to do the same, but still use $result->accessor functions? 

Anyway, it'd be nice if there was a standard workaround to the error (here's the text):

DBD::Sybase::db prepare failed: Server message number=260 severity=16 state=1 line=1 server=SERVER text=Disallowed implicit conversion from data type varchar to data type money, table 'DB.dbo.DATA', column 'Total Cost'. Use the CONVERT function to run this query.Server message number=8180 severity=16 state=1 line=1 server=SERVER procedure=sp_prepare text=Statement(s) could not be prepared. at test_syb.pl line 20.
