I\'m pretty sure the following query used to work for me on Presto:
select segment, sum(count) from modeling_trends where segment=\'2557172\' and date = \'2016-0
Just a quick thought.. have you tried omitting the dashes in your date? try 20160623 instead of 2016-06-23.
20160623
2016-06-23
I encountered something similar with SQL server, but not used Presto.
