Hello,
we are working on a new release of our application, which will support unicode.
When we started with that, my colleague did some research and "ported" the
script for the currently used ISO8859_1 database to UTF8.
We then created the UTF8 database and were developing using it all the time.
Now some testing shall be done and I've discovered some issues:
1. Doing a restore with "commit after each table" option active (using
IBExpert) leads to the error
"Unsuccessful execution caused by system error that does not
preclude successful execution of subsequent statements.
action cancelled by trigger (0) to preserve data integrity.
could not find table/procedure for GRANT."
2. When I turn off this option, the error doesn't occur anymore, but another
one does:
"This operation is not defined for system tables.
unsuccessful metadata update.
MY_PRODUCTS.
COLLATION UNICODE for CHARACTER SET UTF8 is not installed."
There wasn't a problem with that before the restore attempt - I could / can
access that database and work with it.
Unfortunately my colleague is not available, so I don't know how well his
research was, if there were some Firebird related changes inbetween etc.
I would like to post a small part of the database script and to ask you to
check it.
The current application / database ship with Firebord 2.1.3. The new one is
supposed to ship with Firebird 2.5.1

------------------------------------------
There are some more fields for the description etc. but I removed them to make
the list a bit shorter, only leaving 5 of each there.
- Is anything wrong with the ROLES (because of the error in #1)?
- What is wrong with the COLLATION (because of the error in #2)? Does something
have to be installed? Is it the wrong one for the UTF8 character set? Is a
collation needed at all for UTF8?
- Any potential improvements you see? (regarding indexes etc.)
Best regards,
Patrick
