After trying manually to set indices for colums without success I read some notes within forums and mailing lists, that it is a known issue for hibernate not to support index definition - but the reason was not cleared.

So can anyone give me an official source or an information whether indexing ist supported (and how it is done) and if not - why?

Thanks in advanced

Hibernate version:
3.3

Name and version of the database you are using:
MySql 5.1.11

Indexes are supported by the schema generation tools. See http://www.hibernate.org/hib_docs/v3/re ... etguide-s1

It supports both single- and multi-column indexes/unique keys by setting values for the index, unique or unique-key attributes in the mapping files.

This works when creating new a schema only. The SchemaUpdate only works with unique keys.
