Subject [jira] Updated: (SOLR-1348) JdbcDataSource does not import Blob values correctly by default
Date Mon, 07 Sep 2009 08:53:57 GMT


Shalin Shekhar Mangar updated SOLR-1348:

    Attachment: SOLR-1348.patch

This patch adds support for the binary field type in converType logic. I'll commit this shortly.

I've also added the suggested solutions to this problem on the DIH Faq page:

> When blob values are returned through a java ResultSet Object they have the type byte[].

> As byte[] doesn't have a useful toString method we end up with a reference type value
added to the solr document (i.e. [B@1f23c5). 
> The problem is easy to remedy by adding the attribute 'convertType="true"' to the dataSource
tag within data-config.xml.
> However this attribute does not appear to be documented anywhere and I was only able
to find it after a few hours digging through the source code. 
> A simple fix for this would be to change the default value of convertType to true within
the JdbcDataSource class.
