I have an old database running on a Firebird 2.5 server, on which is missing the collations UNICODE_AI and UNICODE_CI. Direct selection on meta tables is indicating this.
select * from RDB$COLLATIONS where rdb$collation_name like 'U%'
returns UNICODE, UNICODE_FSS, UTF8 and UCS_BASIC.
How can I add these collation to my current database?
Doing a backup restore of the meta table solve the issue.
