Subject [jira] [Created] (SOLR-2907) java.lang.IllegalArgumentException: deltaQuery has no column to resolve to declared primary key pk='ITEM_ID, CATEGORY_ID'

java.lang.IllegalArgumentException: deltaQuery has no column to resolve to declared primary
key pk='ITEM_ID, CATEGORY_ID'
-------------------------------------------------------------------------------------------------------------------------

                 Key: SOLR-2907
                 URL: https://issues.apache.org/jira/browse/SOLR-2907
             Project: Solr
          Issue Type: Bug
          Components: Schema and Analysis
    Affects Versions: 3.4
            Reporter: Alan Baker


We are using solr for our site and ran into this error in our own schema and I was able to
reproduce it using the dataimport example code in the solr project.  We do not get this error
in SOLR 1.4 only started seeing it as we are working to upgrade to 3.4.0.  It fails when delta-importing
linked tables.

Complete trace:
Nov 18, 2011 5:21:02 PM org.apache.solr.handler.dataimport.DataImporter doDeltaImport
SEVERE: Delta Import Failed
java.lang.IllegalArgumentException: deltaQuery has no column to resolve to declared primary

I used this dataConfig from the wiki on the data import:

<dataConfig>
    <dataSource driver="org.hsqldb.jdbcDriver" url="jdbc:hsqldb:./example-DIH/hsqldb/ex"
user="sa" />
    <document>

   <entity  name="item" pk="ID" 
   			query="select * from item" 
            deltaImportQuery="select * from item where ID=='${dataimporter.delta.id}'"
            deltaQuery="select id from item where last_modified &gt; '${dataimporter.last_index_time}'">

            <entity name="item_category" pk="ITEM_ID, CATEGORY_ID"
                    query="select CATEGORY_ID from item_category where ITEM_ID='${item.ID}'"
                    deltaQuery="select ITEM_ID, CATEGORY_ID from item_category where last_modified
> '${dataimporter.last_index_time}'"
                    parentDeltaQuery="select ID from item where ID=${item_category.ITEM_ID}">
                
        		<entity name="category" pk="ID"
                        query="select DESCRIPTION as cat from category where ID = '${item_category.CATEGORY_ID}'"
                        deltaQuery="select ID from category where last_modified &gt; '${dataimporter.last_index_time}'"
                        parentDeltaQuery="select ITEM_ID, CATEGORY_ID from item_category where
CATEGORY_ID=${category.ID}"/>
            	</entity>
        </entity>
        
    </document>
</dataConfig>

To reproduce use the data config from above and set the dataimport.properties last update
times to before the last_modifed date in the example data.  I my case I had to set the year
to 1969.  Then run a delta-import and the exception occurs.  Thanks.
