[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5857) SQLServer dialect for varbinary incorrect for 2008

[Gail Badner (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39715#action_39715 ] 

Gail Badner commented on HHH-5857:
----------------------------------

Do the same changes made for HHH-3965 to SQLServer2005Dialect apply to SQLServer2008Dialect?

Currently, SQLServer2008Dialect extends SQLServerDialect. Should it extend SQLServer2005Dialect?

> In SQLServer 2008 the IMAGE data type has been deprecated and replaced with VARBINARY(MAX)
> {quote}
> ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

> The current SQLServer2008Dialect has the mapping (inherirted from SQLServerDialect):
> {code}
> 		registerColumnType( Types.VARBINARY, "image" );
> {code}
> This needs to be reverted to use VARBINARY.
> {code}
> 		registerColumnType( Types.VARBINARY, "varbinary" );

> The issue is identified when using hibernate.ddl.auto=validate, it shows an error such as:
> {quote}
> Wrong column type in Database.dbo.BINARY_OBJECT for column BYTES. Found: varbinary, expected: image
> {quote}
> for an annotated fields such as:
> {code}
>     @Column(name = "BYTES", length = 100000, nullable = true)
>     private byte[] bytes;
