SWI Prolog Interface to ODBC

Hello everyone!
I am having some problems using the SWI Prlog Interface to ODBC. I
have written a program where when a parameter is called, it prints an
SQL statement. I would like to send this statement to ODBC to retreive
the answer. I have tried odbc_query where i put the parameter that
returns the SQL statement into odbc_query, but this didnt work!
Pls help
Thank you
