SQL Server Select in if (subquery Result 0 rows use different statement) -


i have table in sql server 2008 r2 need result subquery. in case subquery returns no results, , in case need these query null condition.

declare @insid int =12288  declare @docentry int = 28  select *  [table1] a.u_insid = @insid   , a.docentry <> @docentry   , a.u_objecttype in ('1','5')   , (month(a.u_periode) in              (select max(month(u_periode))               [table1] e               e.u_insid = a.u_insid                 , e.docentry <> @docentry                 , (a.u_status <> '2' or a.u_status null)) or (a.u_periode null , a.docentry <> @docentry , (a.u_status <> '2' or a.u_status null)) )

in query "or" result on time... want result of "or" when subquery result nothing...

any ideas?

best regards oliver

okay 1 table. query exclude row i'm working on , should return result based on max date(month) , if not there, there row has no value in period. , need this.

in first example "or" these sentence on time... figuerd out working solution minute ago... geues not nice 1 working..

declare @insid int =12288  declare @docentry int = 31 declare @var varchar(30) --- max month u_insid , not actual row '31' set @var = (select max(month(u_periode))      [table1] e      e.u_insid=@insid     , e.docentry <> @docentry      , (e.u_status <> '2' or e.u_status null))  --- if there no result this.... if @var null begin( select * [table1] a.u_insid = @insid , a.docentry <> @docentry , a.u_periode null , (a.u_status <> '2' or a.u_status null) ) end else   ---- if there result... select * [table1] a.u_insid = @insid , a.docentry <> @docentry , month(a.u_periode)=@var  , (a.u_status <> '2' or a.u_status null)

and i'm looking smoother way of doing instead using if... else

i thought there should solution within query itself... best regards oliver

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
