DataImportHandler can't add/update - solr

Question

I am trying to convince solr to perform a bulk import of a sqlite database.
I follow the all instruction from Solr-Wiki.
I configured DataImportHandler to open that database through jdbc successfully and I can start the import http://localhost:8080/solr/dataimport?command=full-import
but whatever I do, DIH didn't add any document even though it seems index the DB
the result
<str name="command">full-import</str>
<str name="Total Requests made to DataSource">1</str>
<str name="Total Rows Fetched">**14**</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2012-04-06 01:14:30</str>
<str name="">**Indexing completed**. **Added/Updated: 0 documents**. Deleted 0 documents.</str>
<str name="Committed">2012-04-06 01:14:32</str>
<str name="Optimized">2012-04-06 01:14:32</str>
<str name="Total Documents Processed">0</str>
I use the emp table in Oracle DB
data-config.xml
<dataConfig>
<dataSource name="jdbc" driver="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:#//localhost:1521/ORCL" user="scott" password="tiger"/>
<document>
<entity name="emp" query="select EMPNO, ENAME from EMP">
<field column="EMPNO" name="empno" />
<field column="ENAME" name="ename" />
</entity>
</document>
</dataConfig>
schema.xml
<field name="empno" type="int" indexed="true" stored="true"/>
<field name="ename" type="string" indexed="true" stored="true"/>
It doesn't seem to index, but not to stored indexed data
Any ideas why this problem happen?
EDIT 1
Log show warning message like..

that kind of log followed and
this warning message show up end of the log
2012. 4. 6 오후 12:12:25 org.apache.solr.update.processor.LogUpdateProcessor finish

I thought missing required field: id has some relation with the configuration in
the schema.xml
<uniqueKey>id</uniqueKey>
but after delete, I got this message
HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: false in solr.xml ------------------------------------------------------------- org.apache.solr.common.SolrException: QueryElevationComponent requires the schema to have a uniqueKeyField implemented using StrField at org.apache.solr.handler.component.QueryElevationComponent.inform(QueryElevationComponent.java:158) at org.apache.solr.core.SolrResourceLoader.inform
Any advice?

Answer 1

Try:
<entity name="emp" query="select EMPNO, ENAME from EMP">
<field column="EMPNO" name="id" />
<field column="ENAME" name="ename" />
in data-config.xml and put back:
<uniqueKey>id</uniqueKey>
in schema.xml and also let the field id.
Or u can simply replace:
<uniqueKey>id</uniqueKey>
with:
<uniqueKey>epno</uniqueKey>
Hope that will work.

You can also add an autoincrement id with
<dataConfig>
<script><![CDATA[
id = 1;
function GenerateId(row) {
row.put('id', (id ++).toFixed());
return row;
}
]]></script>
<dataSource name="jdbc" driver="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:#//localhost:1521/ORCL" user="scott" password="tiger"/>
<document>
<entity name="emp" query="select EMPNO, ENAME from EMP" transformer="script:GenerateId">
<field column="EMPNO" name="empno" />
<field column="ENAME" name="ename" />
</entity>
</document>
</dataConfig>
