mysql - SQL: Combine TWO selects in ONE complex Query -


i have pretty complex query:

$query = "select * element_skanning yt1             join (select objekt_nr, element_nr, vart                 element_skanning                 group objekt_nr, element_nr, vart                 having count(*) > 1)             yt2 on (yt2.objekt_nr=yt1.objekt_nr , yt2.element_nr=yt1.element_nr , yt2.vart=yt1.vart)             order 2";

this how db looks like:

id     objekt_nr     element_nr     vart -----------------------------------------  1         1              1          blå  2         1              1          blå  3         1              1          rosa  4         1              1          kont  5         2              1          rosa  6         2              2          blå

my excisting query give me result: 1&2 because use 3 inputs.

now i´d search third dupe. id: 3
how can result of id: 1,2,3 not 4, 5 , 6?
check should if there row same obj_nr & el_nr "blå" or "rosa" "vart" before.
so, id 3 dupe because of id: 1 & 2.
id: 2, dupe because of 1 & 3.
id: 1, dupe because of 2 & 3.

i did rewrite couple of times, guess that´s why can´t write query.
hope can understand want here?!
, how it?

if understand correctly:

select * element_skanning yt1 join      (select objekt_nr, element_nr       element_skanning       vart in ('blå', 'rosa')       group objekt_nr, element_nr       having count(*) > 1      ) yt2       on yt2.objekt_nr = yt1.objekt_nr ,          yt2.element_nr = yt1.element_nr  vart in ('blå', 'rosa') order 2;

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...
