Subject [jira] Created: (SOLR-2102) JdbcDataSource convertType attribute is not working with implicit fields

JdbcDataSource convertType attribute is not working with implicit fields
------------------------------------------------------------------------

                 Key: SOLR-2102
                 URL: https://issues.apache.org/jira/browse/SOLR-2102
             Project: Solr
          Issue Type: Bug
          Components: contrib - DataImportHandler
    Affects Versions: 1.4.1
            Reporter: Alexey Serba


JdbcDataSource convertType attribute doesn't take any effect on implicit fields ( fields that
are not listed in [field declaration section|http://wiki.apache.org/solr/DataImportHandler#Field_declarations]
). 

For example you might have the following configuration:

{noformat:title=dataconfig}
<?xml version="1.0" encoding="UTF-8"?>
<dataConfig>
  <dataSource batchSize="-1" convertType="true" driver="com.mysql.jdbc.Driver"
    password="pass" url="jdbc:mysql://localhost/test" user="root"/>
  <document name="items">
    <entity query="SELECT title, body, tm FROM articles order by title desc">
    </entity>
  </document>
{noformat}

where 
* tm is timestamp in mysql database
* tm is date in schema.xml

Because field _tm_ is not explicitly stated in fields declaration _convertType_ attribute
doesn't take any effect and as a result you would get the following exception:

{noformat:title=convertType exception}
