I'm getting my server upgraded from MySQL 5.0 to 5.5.
The guy doing the upgrade said he does not guarantee that my queries are forward-compatible.
What kinds of query-related compatibility problems are typical in an upgrade from 5.0 to 5.5?
Nothing in the list at http://dev.mysql.com/doc/refman/5.5/en/mysql-nutshell.html
looks like it will be a problem ... I'm not using a cluster, any partitioning, or any of the "removed features".
Nothing in the list at http://dev.mysql.com/doc/refman/5.5/en/upgrading-from-previous-series.html
jumps out at me either.
But ... from real-world experience ... are there some typical problems?
