Hello,
I am currently upgrading from mysql 5.1.72 -> mysql 5.6 and the migration and upgrade is sound (In a QA ENV). Queries work etc. However, when I run a query similar to "SELECT `table`.* FROM `table` WHERE (some_id IN (13528, 14906, 38845)) ORDER BY `date` DESC LIMIT 1;" on 5.1.72 and on 5.6.15 I get back different data. The date for all of the data are exactly the same to the second.

However, if I run "SELECT `table`.* FROM `table` WHERE (some_id IN (13528, 14906, 38845)) ORDER BY `date` LIMIT 1;" it comes back with the exact same data that is expected.
Is this a bug? Or am I missing here?
Thanks!
