Yes, that can be the reason but i think something like this will be also not possible - if you change datatype of domain not only collation – i think. But this should be possible by introduce command like ALTER DOMAIN ALTER TYPE VARCHAR(150) COLLATION PXW_PLK REBUILD; <- here we add rebuild command. But i think about BLR – is colltion compiled into blr of procedures and triggers? If yes then also this objects should be rebuilded by “REBUILD” command. Now doing something like this makes you have a headache regards, Karol Bieniaszewski [Non-text portions of this message have been removed]

It is not clear why you included a COLLATE clause in an ALTER DOMAIN statement. You can't change the COLLATE property of a domain, which is why you got the error: COLLATE is not expected in an ALTER DOMAIN statement. But you were not trying to change that, anyway. An ALTER DOMAIN statement does not drop the existing domain. It allows valid changes to properties that can be changed. All you needed here was: ALTER DOMAIN XXX TYPE VARCHAR(150) It is allowed, because (1) VARCHAR and VARCHAR are compatible and (2) the new size is longer than the old size. No other properties are affected. HB

Hi, we have 2.05, tough. So I am not sure for 3.x. Sorry. Well, if you install IBExpert or some similar tool, you would be able to see immediately.
