Commented by: @paulvink I checked with the developer and yes, this too is a supported (but so far undocumented) feature from version 2.1 onward: CAST(<expr> AS [TYPE OF] <domain>) Again, I'll document it in the LangRef and pass the ticket on to Helen for the Release Notes. |

If we define a domain:
CREATE DOMAIN DINTEGER AS INTEGER
FB2.1.3 allows
CAST(123 AS DINTEGER)
and
CAST(123 AS TYPE OF DINTEGER)
however I cannot find where this new feature is described in Release Notes.
Is it an official feature of just a side effect of something else?
