How to read Oracle CLOB data type


I'm developing an app in Delphi 5 with Oracle 8i as database and Win 98
as OS.
One of the tables used has a CLOB data type column but I can't read this

column through a normal query, it always returns 'Invalid field type' as

an error message.
I tried to look for something in the BDE but I couldn't find any help
there either.
Is there any setting I'm missing? Please help me.
