[appengine-java] Use Array as a query filter - possible?
Hey I have an entity with an Int Array and I would like to perform a query on the contents of the Array. For example, I would like to return entities which have a certain number within the array, I.e. Select * From MyObject Where numberArray contains 2 Is this possible in any way, shape or form?

Re: [appengine-java] Use Array as a query filter - possible?
Yes it's possible. Make sure the property is indexed. From the data viewer you can perform the following query for example: select * from KIND where PROPERTY = NUMBER How you do it in code depends on if you're using JDO, Objectify, JPA, low-level API, etc. On Sun, May 8, 2011 at 5:14 PM, mscwd01 mscw...@gmail.com wrote: Hey I have an entity with an Int Array and I would like to perform a query on the contents of the Array.

BTW, I'm assuming by Int Array you actually meant ArrayList or multi-valued equivalent. Perhaps more info is needed for your particular situation and why it seems you think it can't be done.
