Yes, Firebird has the same limitation. By the way, the limit is 255
metadata changes to any single table - that's a lot of changes to a

Historically, it has not been considered a priority to extend this
limit. It is perhaps something which can be considered as part of a
major ODS revision (which would not be backward compatible).

You can incorporate a backup and restore within your application - just
don't ever overwrite the existing database, restore to a temp file,
rename the original file, change temp file to original filename.

Does anybody know if Firebird has this limit of 255 metadata changes?
creating a program that would make the necessary modifications on my
clients servers. But if there's a limit on the changes, this could be
dangerous for me, since most of my clients had guidance on installing
software and don't want to take the time for maintenance. I have one
question, if I incorporate in the software the backup and restore(with
replace), would this work?

Thank you in advance.
