java - Is it possible to write Join Condition explicitly? -

i want write bring together status explicitly on non key columns using jdoql in datanucleus.is possible write in datanucleus?if yes how can write using jdoql?

you don't write joins in jdoql. whole point of jdoql ... java syntax, , using object relationaships. if object "model" has assorted longs/ints around think relationships need revisit design, since not o-o. same applies jpa fwiw, except can explicit joins joined on intents , purposes relation field (i.e not on non-key columns).

you set status (for non-key columns) filter of jdoql query (as long have field in persistable class) equates want do.

java datanucleus jdoql
