Hi all, I'm trying to query JPA datastore.
Let's assume that we have a Product entity with ProductId as the primary key and Prodqty and ProdPrice as attributes. An example might look like this. ProductId Prodqty ProdPrice 1 50 1000 2 34 998 3 45 34343 4 34 998 5 43 232 6 50 1000 Now I'd like to retrieve the rows that are duplicated , that is having the same values for both ProdQty and ProdPrice. The result for the above example will be 50 1000 34 998 http://code.google.com/appengine/docs/java/datastore/usingjpa.html#Unsupported_Features_of_JPA says that aggregate functions are not supported. Can anyone suggest how to specify a query for this purpose? Thanks -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
