thanks Niels! so you are saying this command should work, correct? it currently does not..
"SELECT str_to_date( '1/1/2014' , '%m/%d/%Y' ) as date"
if i am on windows, do i need to install strptime separately? i am currently hitting this error that (from the version tracker) seems like it should've been resolved?
on windows this maybe a problem indeed. strptime etc support doesn't exist on windows.
