FreeTDS support already sp_prepare/sp_execute/sp_unprepare calls (using
tds_submit_prepare, tds_submit_execute, tds_submit_unprepare). We have
some problem with Sybase and blob fields. ct_dynamic is planned for
0.62... I think you just want prepare/execute/unprepare type, not
cursors and others (I readed a bit ct_dynamic documentation on Sybase
site).
