[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2304) Wrong type detection for sql type char(x) columns

[Krashan Brahmanjara (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_29644 ] 

Krashan Brahmanjara commented on HHH-2304:
------------------------------------------

Patch for dialect/Dialect.java  for correct mapping char to string

   registerHibernateType( Types.BIT, Hibernate.BOOLEAN.getName() );
- registerHibernateType( Types.CHAR, Hibernate.CHARACTER.getName() );
+ registerHibernateType( Types.CHAR,1, Hibernate.CHARACTER.getName() );
+ registerHibernateType( Types.CHAR,255, Hibernate.STRING.getName() );
   registerHibernateType( Types.DATE, Hibernate.DATE.getName() );
   registerHibernateType( Types.DOUBLE, Hibernate.DOUBLE.getName() ); 


With "length patch" from earlier comment it allow for correct mapping  CHAR(?) column types with Informix drivers.

When patch HHH-3147 will be added will be posiible to read namedQueries without column names

> 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.
