I'm trying on Filter in property IB_Query:
PRODID IN (::SELECT PRODID FROM FORNECPROD::)
but show me a message error with "-104 Token Known SELECT".
I'm using D5, IB6, IBO3.6Ce

Because?

A document release to 3.6Ce say:
"...I fixed various glitches in the Filter parsing routines. I also
added the ability to preface the Filter with ::SQL:: so that all
parsing will be bypassed and the text will be sent to the server
directly as SQL in the WHERE clause ..."
