Inserting values into set attributes (fwd)

days now. Can anyone help?

Subject: Inserting values into set attributes

Hi,
In the create_table manual page I saw the last example where an attribute
is of a composite (or complex or set) type. That is all fine, but where
is an example on how to insert values into such an attribute?

Any suggestions?

Thanks
Kostas
