Hi guys,
I found this defect in branch 5.2.5 of hibernate-orm module.
Following is the error message:
Code:

And my environment:
- Windows 7 x64
- Eclipse IDE MARS r2
- SQLServer 2014 x64
- Microsoft SQL Server Driver 6.1
When the exception has been triggered, I tracked the error message in stack. And there are some lines could be tracked in source code.
- Types.java line: 286
- AbstractTransactSQLDialect.java line: 41
- SQLServerDialect.java line:41
- Dialect.java line: 216
Usually, I will create a sub-class to extend SQLServerDialect.
Code:
public class SQLServerJDBC4Dialect extends SQLServerDialect {
public SQLServerJDBC4Dialect() {
super();
registerHibernateType(-9, "string");
registerHibernateType(Types.NVARCHAR, StandardBasicTypes.STRING.getName());
}
}
After some digging, I think this defect could be fixed in source code. I plan to do some changes in the above files and test in my local.
What do you think? Could I get a invitation for this defect fixing?
Your ideas are welcome!
Thanks,
Max
