[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3892) Improve support for mapping SQL LONGVARCHAR and CLOB to Java String, SQL LONGVARBINARY and BLOB to Java byte[]

[Gail Badner (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33426#action_33426 ] 

Gail Badner commented on HHH-3892:
----------------------------------

Updated org.hibernate.dialect.Dialect to register Types.LONGVARCHAR and Types.LONGVARBINARY to hibernate "text" and "image", respectively.

I added some tests for selecting "image" and "text" properties using native SQL and some tests for overriding CRUD operations for entities containing an "image" or "text" property.

> Property types will be provided to enable an application to process data for a java.sql.Types.LONGVARCHAR or java.sql.Types.CLOB column as a Java String. Hibernate will internally process the data as a streams. On a read, stream data will immediately be materialized into a Java string.
> text - property type to map java.sql.Types.LONGVARCHAR column data as a Java String (via org.hibernate.type.TextType);
> (NOTE: currently, org.hibernate.type.TextType incorrectly maps "text" to java.sql.Types.CLOB; this will be fixed by this issue and updated in database dialects)
> materialized_clob - property type to map java.sql.Types.CLOB column data as a Java String (via org.hibernate.type.MaterializedClobType);
> In addition, new property types will be provided to enable an application to process data for a java.sql.Types.LONGVARBINARY or java.sql.Types.BLOB column as Java byte[]. Hibernate will internally process the data as a streams. On a read, stream data will immediately be materialized into a Java byte[].
> image - property type to map java.sql.Types.LONGVARBINARY column data as byte[] (via org.hibernate.type.ImageType);
> materialized_blob - property type to map java.sql.Types.BLOB column data as byte[] (via org.hibernate.type.MaterializedBlobType);
