Hi Folks,
I'm preparing an upgrade of a 5.0.51a database to 5.1.58 (Ubuntu 11.10) -
Some of the table names contain invalid characters which mysql_upgrade
(mysqlcheck) is attempting to escape by renaming the filename. However I'm
having trouble with some tables with long names.
For instance if I had a table in "some_db" called: "A table with a really
long name - and some invalid characters"
Internally this will be converted to "#mysql50#A table with a really long
name - and some invalid characters" but it will be truncated to 64
characters: "#mysql50#A table with a really long name - and some invalid
char" and I will get errors such as:
Failed to RENAME TABLE `#mysql50#A table with a really long name - and
some invalid char` TO `A table with a really long name - and some invalid
char`
Error: Can't find file: './some_db/A table with a really long name
- and some invalid char.frm' (errno: 2)
Any ideas or suggestions ?
I'd prefer to keep with the ubuntu version of mysql if possible. Would also
like to minimize the size of the downtime window.
Would it be best to just dump/drop/re-import the tables/databases ?
Many Thanks,

The simple solution is to rename your tables to
a) use shorter names
and b) not use any illegal characters
Are those odd characters and long names really a requirement to your
design or are they there just for developer's convenience?
