Hi Con, what RDBMS are you using?
This looks like a SQL syntax problem, perhaps the 'literal as column' is not right for your setup [while it works for my MS SQL Server]. An alternative to supplying the "rowtype" attribute as a literal in the SQL clause is to use a Solr DIH Template Transformer http://wiki.apache.org/solr/DataImportHandler#transformer This should allow you to keep the working SQL. For example <entity name="user" transformer="TemplateTransformer" query="select * from USER"> <field column="rowtype" template="user" /> </entity> > -----Original Message----- > From: con [mailto:[EMAIL PROTECTED] > Sent: Wednesday, 1 October 2008 5:48 PM > To: solr-user@lucene.apache.org > Subject: RE: How to select one entity at a time? > > > That is exactly what my problem is.:handshake: > Thanks for you reply. > > But I tried your suggestion: > Updated the data-config.xml as; > > <entity name="user" query="select 'user' as rowtype, * from > USER"></entity> > <entity name="manager" query="select 'manager' as rowtype, * from > MANAGERS"></entity> > > But when I perform the full import itself, it is throwing exception, > > SEVERE: Exception while processing: user document : > SolrInputDocumnt[{}] > org.apache.solr.handler.dataimport.DataImportHandlerException: > Unable to > execute > query: select 'user' as rowtype,* from USER Processing Document # 1 > ....... > So, as expected, when I go to search it is giving- undefined field > rowtype- > error.!!! > Do I need to update any other files or fields? > > I am happy that it worked for you...:jumping::jumping: > Looking forward for your reply > Thanks > con > > > > > Neville Burnell wrote: > > > > Hi, > > > >> But while performing a search, if I want to search only the data > from > >> USER table, how can I acheive it. > > > > In my app+solr index, we solved this problem by "tagging" entities > with a > > "rowtype" attribute, something like this: > > > > <entity name="user" query="select 'user' as rowtype, * from > > USER"></entity> > > <entity name="manager" query="select 'manager' as rowtype, * from > > MANAGERS"></entity> > > > > Then your 'users' only query becomes something like: > > > > http://localhost:8983/solr/select/?q=(bob AND > > rowtype:user)&version=2.2&start=0&rows=10&indent=on&wt=json > > > > Hope this helps > > > > > > > >> -----Original Message----- > >> From: con [mailto:[EMAIL PROTECTED] > >> Sent: Wednesday, 1 October 2008 4:54 PM > >> To: solr-user@lucene.apache.org > >> Subject: Re: How to select one entity at a time? > >> > >> > >> Of course I agree. > >> But while performing a search, if I want to search only the data > from > >> USER > >> table, how can I acheive it. > >> > >> Suppose I have a user name bob in both USER and MANAGER tables.
