how to insert zipped data into mysql using HTSQL_printf ?

Hi all,

I would like to insert  zipped data in my  mySQL database but  formats
provided by HTSQL_printf obviously don't match my case. It does not seem
to allow binary data  as it processes strings.

Am I wrong ?

Has anybody a clue  to achieve this ?

I use libwww-5.2.8.

Thanks.
