Hi,
I'm new to the core data with the iphone cocoa program. In my application I need to use core data with predicate to query the SQLite database.
It has a date field with the data type as TimeStamp. I try to use the SQLite function datetime(), as :
datetime(arrive_time) < datetime('2009-06-23 11:30:00')
but it has the compilation error. And when I used the datetime() function in one side, like :
arrive_time < datetime('2009-06-23 11:30:00')
Can I use the NSDate object to pass into the predicate format string directly and do the comparison?
Thanks much,
jliu69
