Hi,
I know, IB can't create index for a computed by column.
I see, but WHY CAN'T?
(I have got an error message: ATTEMPT TO INDEX COMPUTED BY COLUMN)
It should be a good feature.
for example:
Field with a national character set but haven't a good collate (I can
write a good UDF)
(It's my problem actually, I need store a second 'seek' field with
modified content)
or
SOUNDEX computed field (with UDF) (It's will problem)
or (but it too abstract for me)
index for a field of related table (like dbase)
I think that, this feature 'be inside' in IB, only a few work need for it.
eMeL
(sorry for my poor english)
