Hello, I have an instance where I suspect Matlab might be not allowing a large SQL Select query to be processed.

Are there any settings in setdbpref or elsewhere that constrains matlab to small queries?

Thanks, AMK

This page

http://www.mathworks.com/help/database/ug/preference-settings-for-large-data-import.html

discusses Java heap memory issues with importing large query results.

I personally have not had success in processing queries in batches via the method described there. For my large queries (~millions of rows), I have needed to wrap the query in a for loop, and use SQL's "offset" and "limit" clauses to do the batching within SQL.
