Re: [rt-users] ERROR 1062 during 3.4.5 - 3.8.2 database update
One more follow up -- turns out that the ERROR 1062 was due to a failed database dump and restore. I needed to add --set-charset=binary to my mysqldump command line when dumping the old RT database, and just in case I added set names 'binary' to the top of the resulting dump before importing it. After that the sql.queries generated by upgrade-mysql-schema.pl worked fine without modifying the queries. On Thu, 19 Feb 2009, Jim Faulkner wrote: Just wanted to follow up on this.

Re: [rt-users] ERROR 1062 during 3.4.5 - 3.8.2 database update
I had the same problem and it was caused by accents, since mysql has no accent sensitive collations (_as) aside from utf8_bin which is everything sensitive, I basically just removed the user (or rename) to fix the issue. Since emails generally shouldn't have them it's pretty safe to do, the old latin collations did support them to some degree. Jim Faulkner wrote: Just wanted to follow up on this.
