[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3161) No Dialect mapping for JDBC type: -4

Tajinder Singh commented on HHH-3161:
-------------------------------------
I have a similar issue with Hibernate3 + mysql-connector 5.1.6 .
my hibernate mapping is like : -
<property name="testObject" >
<column name="object" sql-type="java.sql.BLOB"/>
</property>
I could save blob (save the object) using same mapping. But when I try to load it from the
DB table, it gives me following exception :-
org.hibernate.MappingException: No Dialect mapping for JDBC type: -4.
Please note that, I could save and retrieve the blob when I use resultset object instead
of Hibernate.
The current workaround I am using is, saving a blob using hibernate, and retrieving it
using resultSet object.

Key: HHH-3161
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3161
Project: Hibernate3
Issue Type: Bug
Components: core, query-hql, query-sql
Affects Versions: 3.2.1
Environment: hibernate 3.2.1 + mysql
Reporter: cyrus
Priority: Critical
When I execute the statement below:
SELECT concat(case ip_protocol when 6 then 'TCP' when 17 then 'UDP' else
'OTHER' end, ', PORT ', repeat(' ', 5 - length(if(port is NULL, 0,
port))), if(port is NULL, 0, port)) as protocol, concat(case ip_protocol when 6 then
'TCP' when 17 then 'UDP' else 'OTHER' end, if(port is NULL, 0,
port)) as id, sum(byte_subtotal) as total FROM usage_sum_minute WHERE
from_unixtime(time_min * 60) between '2008-02-03 14:00:00' and '2008-03-05
13:59:00' GROUP BY protocol ORDER BY total DESC LIMIT 0, 20
DB schema:
