Question

I have the problem when solr put some unexpected value in field.

in schema.xml

<field name="country_ids" type="string" multiValued="true" stored="true" indexed="true" />

in media-jdbc.xml

<field column="country_ids" splitBy="\|" />

and query returns NULL or 2|3|8|9|3 for this field. (all query is to big and works perfectly)

When i do query in browser.

the field holds strange value:

<arr name="country_ids">
    <str>[B@6ad21538</str>
</arr>

What I’m missing?

Solr version 3.5

Answer 1

Ok! So i was using this query for importing:

(select group_concat(distinct mmpc.mediacountry_id separator '|') from media_media_production_countries mmpc where mmpc.media_id=m.id) as country_ids

After edited it slightly I’ve got right results.
Changed it to:

convert((select group_concat(distinct mmpc.mediacountry_id separator '|') from media_media_production_countries mmpc where mmpc.media_id=m.id) USING latin1) as country_ids

If you noutice i added conver(**MY_STATEMENT** USING latin1)

But steel cant explain why. I would appreciate if someone give me an explanation.
