Interval day to second problem with ODBC

Hi Folks, I'm trying to obtain the records of the ph_task table in sysadmin db into an ODBC app. I've noticed that interval year to date fields in this table were the origin of the errors encountered. For example you can test it with the Connect Test Demo with the SQL Script "Select tk_delete from ph_task" returning "Unkown SQL Type -110". I thougth it was possible to escape from the error with a view based on the table with converted types, but i can't imagine that the data types are not supported by client odbc apps. Any idea ? Using IDS 11.50.TC9 on WinServer2003 and Informix Connect 3.70 on 7/32 Client.
