Fixing Script Errors After Migration from MySQL 5.1 to MySQL 5.5

For IONOS Linux hosting and managed servers with MySQL databases

You have moved your data from a MySQL 5.1 database to a newly created MySQL 5.5 database - or your existing database has been converted - and now you get SQL syntax script errors when calling your website? Then your database probably uses certain keywords as table or column names, which are now reserved for SQL statements since MySQL 5.5.

See the article Reserved Words in MySQL 5.5 (Reserved Words) to learn which keywords are affected and how to fix these errors.
