RE: Problem with DIH delta-import on JDBC

[safl]

Hi,

I did a debugger session and found that the column names are case sensitive
(at least with Oracle).
The column names are retreived from the JDBC metadatas and I found that my
objectid is in fact OBJECTID.

So now, I'm able to do an update with the following config (pay attention to
the OBJECTID):

entity name=test pk=OBJECTID
query=select * from table
deltaImportQuery=select * from table where
objectid='${dataimporter.delta.OBJECTID}'
deltaQuery=select objectid from table where lastupdate 
'${dataimporter.last_index_time}'
/entity


Is there a way to be case insensitive ?

Anyway, it works now and that's the most important thing!
:-)

Thanks to all,
 Florian

 Hi,
 
 It looks like the deltaImportQuery needs to be changed you are using
 dataimporter.delta.id which is not correct, you are selecting objected in
 the deltaQuery, so the deltaImportQuery should be using
 dataimporter.delta.objectid
 
 So try this:
 
 entity name=test pk=objectid
 query=select * from table
 deltaImportQuery=select * from table where
 objectid='${dataimporter.delta.objectid}'
 deltaQuery=select objectid from table where lastupdate 
 '${dataimporter.last_index_time}'
 /entity

Problem with DIH delta-import on JDBC

[safl]

Hello,

I'm just new on the list.
I searched a lot on the list, but I didn't find an answer to my question.

I'm using Solr 1.4 on Windows with an Oracle 10g database.
I am able to do full-import without any problem, but I'm not able to get
delta-import working.

I have the following in the data-config.xml:

...
entity name=test pk=objectid
query=select * from table
deltaImportQuery=select * from table where
objectid='${dataimporter.delta.id}'
deltaQuery=select objectid from table where lastupdate 
'${dataimporter.last_index_time}'
/entity
...

I update some records in the table and the try to run a delta-import.
I track the SQL queries on DB with P6Spy, and I always see a query like

select * from table where objectid=''

Of course, with such an SQL query, nothing is updated in my index.

It behave the same if I replace ${dataimporter.delta.id} by
${dataimporter.delta.objectid}.
Can someone tell what is wrong with it?

Thanks a lot,
 Florian

That's right. I get the dataimport.properties in conf directory after full
import and the deltaQuery looks like:

select objectid from table where lastupdate  '2010-04-28 10:28:04'


If I execute the statment above directly in Oracle, I get the right list of
objectids which have been modified.

The problem remains on the deltaImportQuery.

Thanks for the hint,
 Florian
