------------------------------------
(Using mysql 5.0) when the data in the column is the empty string, I get:
java.lang.StringIndexOutOfBoundsException: String index out of range: 0

I have found the following workaround for native queries:
instead of
select val from table
do
select cast(val as char) from table
Wrong type detection for sql type char(x) columns
-------------------------------------------------
Key: HHH-2304
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2304
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.2.0.ga
Environment: Hibernate 3.2.0, Oracle 9.2, Oracle JDBC driver 10.2
Reporter: Markus Heiden
Attachments: hibernate.zip
When executing a sql query which returns columns of sql type char(x), a
java.lang.Character is returned. This leads to returning just the first character of the
value. In my eyes a String should be returned when the char(x) type has a width > 1. I
wasn't able to determine whether this is a jdbc driver issue or a hibernate issue.
When using sql type char(x) for columns of entities no such problems occur.
Test case is attached.
