it requires using cursor. DAL select requires fetching all records. The issue it, can we retrieve more than 1000 records looping over them using cursor instead of using fetch? I have not tried but my impression is that there is a tradeoff. we overcome a limitation (1000 records) by requiring more computing time for the app (even when below the limit). Moreover: 1) there is no way to know in advance how many records to fetch because count() is limited to 1000 2) the documentation says this only works with some queries.
I think we just just wait Google figures out this is crazy and they should remove the limitation in fetch and count.
