Types of the values sent by the prompt

[Sunchaser]

Dear all,

I would like to know if something is possible to do in order to have a "textBlob" or a "clob" as the type of value given by a prompt, instead of "integer", "string", etc ...
It seems that, at this level, Cognos doesn't handle anything like "clob"; am I right ?

And what about something like an array ? is it possible ? And how work with it in the database point of view ?

Thanks.
