To fix the issue you can do I have these two tables: , Try this: code :
SELECT DISTINCT sub . * , t2.plan_name, t2.plan_month, t1.plan_name, t2.parent_id
FROM subscription_plan AS t1
LEFT JOIN subscription_plan AS t2 ON t2.parent_id = t1.subscription_plan_id
JOIN subscription AS sub ON t2.subscription_plan_id = sub.subscription_plan_id
WHERE t2.plan_name IS NOT NULL
AND sub.user_id =71
AND sub.property_id =981
ORDER BY sub.subscription_plan_id ASC

Any of those help I'm just getting started with solr but thought this is somewhat counterintuitive. Please help. , You can use this as a fieldType. code :
<fieldType name="strings" class="solr.TextField" sortMissingLast="true" omitNorms="true">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- <tokenizer class="solr.KeywordTokenizerFactory"/>-->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>

Hope this helps Let's say I have two fields in a table. For the purpose of discussion let's say the fields are first name and last name. I want to know how many times the first name shows up listed next to the same last name. Assuming the last name column is unique, how do I figure out how many times each first name exists for each last name? , Simple aggregation? code :
select last_name, first_name, count(*)
from myTable
group by last_name, first_name
order by last_name, first_name
