i am developing a web-application with messages in an openbase
database.
these messages have a NSTimestamp value with the time it was written.
i want to make a search on these messages and with text-search it
worked.
how can i filter objects that are written on one day?
i tried to use:
searchdate = new NSTimestamp(ayear, amonth, aday, 0, 0, 0, atimezone);
qualsearch = EOQualifier.qualifierWithQualifierFormat ("timestamp =
'"+
searchdate()+"'", null);
EOQualifier.filterArrayWithQualifier(messageList, qualsearch);
The above should work if your timestamps are precise to no less than
a day; i.e., the hours, minutes, seconds, milliseconds are 0.
But if your timestamps are precise to the millisecond, then you'd
need to use a qualifier for a timestamp range.
searchdateStart = new NSTimestamp(ayear, amonth, aday, 0, 0, 0,
atimezone);
searchdateEnd = searchdateStart.timestampByAddingGregorianUnits(0, 0,
1, 0, 0, 0);
qualsearch = EOQualifier.qualifierWithQualifierFormat ("timestamp >=
%@ and timestamp < %@", new NSArray(new NSTimestamp[]
{searchdateStart, searchdateEnd}));
Aloha,
Art
