sql - Get values from a row based on some rules -


i trying solve how handle sql query aggregate data together. here sample data set.

site     status     vendor           1234     rejected   joe 1234     rejected   john 1234     approved   jane 1234     rejected   jeb 5644     rejected   joe 5644     rejected   john 5644     in process jane 8877     rejected   joe 8877     rejected   john

i resulting data set following

1234    approved   jane 5644    in process jane 8877    rejected

there can anywhere between 1 , 10 records same site. there hierarchy status. example if of statuses on site approved of others not matter.

i realize similar question other questions have been asked before. first post. if find post seems match looking feel free share it.

here example of query had written:

select distinct [site]    ,(select          case              when min(status) = 'completed' 'completed'             when min(status) = 'in process' 'shopping'             when min(status) = 'rejected' 'rejected'             when min(status) = 'withdrawn' 'withdrawn'             when min(status) = 'hold' 'hold'              else 'no status'          end status      [dbo].[test] subtest     test.site = subtest.site , subtest.overallstatus = 'a' group site) test_status      ,vendor  [dbo].[test] test overallstatus = 'a' order site

sorry editing code environment , might have missed changes. overallstatus value in table not shown.

it bit strange there no vendor on rejected. but, 1 way prioritization using row_number() fancy order by:

select site, status,        (case when status <> 'rejected' vendor end) vendor (select t.*,              row_number() on (partition site                                 order (case when status = 'approved' 1                                                when status = 'in process 2                                                else 3                                           end)                                ) seqnum       t      ) t seqnum = 1

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
