DataImportHandlerException: Unable to execute query

6.3k Views Asked by At

I have tried to search for my specific problem but have not found solution. I have also read the wiki on the DIH and seem to have everything set up right but my Query still fails. Thank you for your help

I am running Solr 3.1 with Tomcat 6.0 Windows server 2003 r2 and SQL 2008

I have the sqljdbc4.jar sitting in C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib

My solrconfig.xml

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
  <str name="config">db-data-config.xml</str>  
  </lst>
  </requestHandler>

My db-data-config.xml

<dataConfig>
<dataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"      url="://localhost:1433;DatabaseName=KnowledgeBase_DM" user="user" password="password" /> 
<document>
<entity name="Titles" query="SELECT mrID, mrTitle from KnowledgeBase_DM.dbo.AskMe_Data">
<field column="mrID" name="id" />  
<field column="mrTitle" name="title" />  
<entity name="Desc" query="select meDescription from KnowledgeBase_DM.dbo.AskMe_Data">
<field column="meDescription" name="description" />  
</entity>
</entity>
</document>
</dataConfig>

It looks like you forgot to describe the protocol you want to use to connect to your database. For MSSQL it is 

url="jdbc:sqlserver://localhost:1433;DatabaseName=KnowledgeBase_DM"

I'm pretty sure you do not need to restate tue database name in you query since you have selected it in you url. Wich makes the query to: 

 query="SELECT mrID, mrTitle from dbo.AskMe_Data"

I have never worked wit MSSQL so i do not know if you should use dbo.AskMe_Data or just, like I always use it, AskMe_Data

I think this code should fix the problem:

<dataConfig>
    <dataSource  type="JdbcDataSource" driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
        url="jdbc:sqlserver://localhost:1433;DatabaseName=KnowledgeBase_DM" user="user" password="password" /> 
    <document>
        <entity name="Titles" query="SELECT mrID, mrTitle from dbo.AskMe_Data">
            <field column="mrID" name="id" />  
            <field column="mrTitle" name="title" />  
            <entity name="Desc" query="select meDescription from dbo.AskMe_Data">
                <field column="meDescription" name="description" />  
            </entity>
        </entity>
    </document>
</dataConfig>

The sqljdbc4.jar should be placed in another directory

If this is the place for you config files

C:\Program Files\Apache Software Foundation\Tomcat 6.0\solr\conf\solrconfig.xml

Then the sqljdbc4.jar should be placed here:

C:\Program Files\Apache Software Foundation\Tomcat 6.0\solr\lib\sqljdbc4.jar
