Hi everyone:
I want to create table use Hibernate SchemaExport . But I found that If I use native generator create string id hibernate can't create table. And it report error.
The problem is exactly as the same as this:
http://opensource.atlassian.com/projects/hibernate/browse/HB-1113
Mysql "native" id generator fails if id's type is String. Why? It hibernate 2.1.6's bug?
Help!
