Solr delta import does not work - sql

Question

I am using solr 4.2. Note that full import works but somehow delta import doesn't. Delta import does not give any error but never fetches any changes. Here's the data config file.
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver:testsql;databaseName=test"
user="dba"
password="dba"/>
<script>
<![CDATA[
function metadataTransformer (row) {
var attributeName = row.get("attribute_name");
var attributeValue = row.get("attribute_value");
row.put(attributeName, attributeValue);
return row;
}
]]>
</script>
<document name="PRODUCTS">
<entity name="product" query="select distinct p.product_id as id from products p
inner join products_meta pm on p.product_id = pm.product_id
inner join meta m on pm.meta_id = m.meta_id
where m.meta_type_id = 11 order by id desc"
deltaImportQuery="select distinct p.product_id as id from products p
inner join products_meta pm on p.product_id = pm.product_id
inner join meta m on pm.meta_id = m.meta_id
where m.meta_type_id = 11 and p.product_id='${dih.delta.product_id}'"
deltaQuery= "select distinct product_id as id from products
where updtime > '${dih.last_index_time}'">
<field column="id" name="id"/>
<entity name="attribute" query="select attribute_name,attribute_value from solr_import
where id =${product.id}" transformer= "script:metadataTransformer">
</entity>
</entity>
</document>
</dataConfig>
Here's what I have tried without any luck.
changing p.product_id='${dih.delta.product_id} to p.product_id='${dih.delta.id} and other way also.
changing where updtime > '${dih.last_index_time}'" to where updtime > '${dih.last_index_time}'"
Please help.

Answer 1

This is fixed. The issue was solr box was on UTC timezone. Once I converted that to ET timezone, delta import started working fine.
Hope this helps someone else.

If you don't want to use ${dih.last_index_time} (server's time config problem), you can try mysql query like:
deltaImportQuery="SELECT * FROM table_name where id='${dataimporter.delta.id}'"
deltaQuery="select id from table_name where update_time > SUBTIME( NOW( ) , '0:15:0' )
I used with crontab and worked fine!
