sql - Detect overlapping date ranges from the same table -

-

i have table following data

pkey  start       end         type ====  =====       ===         ==== 01    01/01/2010  14/01/2010  s 02    15/01/2010  31/01/2010  s 03    05/01/2010  06/01/2010

and want following results

pkey  start       end         type ====  =====       ===         ==== 01    01/01/2010  14/01/2010  s 03    05/01/2010  06/01/2010

any ideas on start? lot of reading i've done suggests need create entries , each day , join on matching days, way?

if have entries each day should work, if don't overhead significant, , if query used often, if affect performance.

if data in format, can detect overlaps using simple date arithmetic, because overlap 1 interval starting after given interval, before given finished, like

select dr1.* date_ranges dr1 inner join date_ranges dr2 on dr2.start > dr1.start -- start after dr1 started   , dr2.start < dr1.end -- start before dr1 finished

if need special handling interval wholly within interval, or need merge intervals, i.e.

pkey  start       end         type ====  =====       ===         ==== 01    01/01/2010  20/01/2010  s 02    15/01/2010  31/01/2010  s

yielding

start       end         type =====       ===         ==== 01/01/2010  31/01/2010  s

you need more complex calculation.

in experience kind of problems, once how calculation hand, it's easy transfer sql :)

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
