Dear Arjen,

Thanks. I did check the uppercase letter.
With a date-type column "deliveryDays" in a table "bsbm.offer", here is the result
- SELECT "deliveryDays" FROM bsbm.offer           --> WORKS
- SELECT "deliverydays" FROM bsbm.offer            --> FAILS
- SELECT "offer.deliveryDays" FROM bsbm.offer    --> FAILS
- SELECT deliveryDays FROM bsbm.offer             --> FAILS
- SELECT offer.deliveryDays FROM bsbm.offer      --> FAILS
- SELECT offer."deliveryDays" FROM bsbm.offer   ---> WORKS

The last query is the one I need :)

Again, thanks for the help.

Regards
Freddy

I would not consider it a bug. The catch is the uppercase letter in
deliveryDays. The default handling of upper/lowercase characters is
different than in other RDMBS. So in some cases the quotes are necessary.
