RE: DIH and denormalizing
In your query 'query=SELECT webtable as wt FROM ncdat_wt WHERE
featurecode='${ncdat.feature}' .. instead of ${ncdat.feature} use
${dataTable.feature} where dataTable is your parent entity name.

Subject: DIH and denormalizing
I am trying to do some denormalizing with DIH from a MySQL source.
Here's part of my data-config.xml:
entity name=dataTable pk=did
query=SELECT *,FROM_UNIXTIME(post_date) as pd FROM ncdat WHERE
did ${dataimporter.request.minDid} AND did =
${dataimporter.request.maxDid} AND (did %
${dataimporter.request.numShards}) IN (${dataimporter.request.modVal})
entity name=ncdat_wt
query=SELECT webtable as wt FROM ncdat_wt WHERE
featurecode='${ncdat.feature}'
/entity
/entity
The relationship between features in ncdat and webtable in ncdat_wt (via
featurecode) will be many-many. The wt field in schema.xml is set up
as multivalued.
It seems that ${ncdat.feature} is not being set. I saw a query
happening on the server and it was SELECT webtable as wt FROM ncdat_wt
WHERE featurecode='' - that last part is an empty string with single
quotes around it. From what I can tell, there are no entries in ncdat
where feature is blank. I've tried this with both a 1.5-dev checked out
months ago (which we are using in production) and a 3.1-dev checked out
today.
Am I doing something wrong?
Thanks,
Shawn

I knew it would be something stupid like that. I thought I changed
everything, looks like I forgot one. Thank you! From what I can tell
now, it's working. Sure is a lot slower now that it's got to do another
query for every item.

Try ${dataTable.feature} instead.
