SQL server where clause (compare more values in more values) - 


select * customers ('paris','london', 'dublin', 'venice')  in (select city europe)

select city europe return more 1 value,

how can this?

i dont want repeat condition like:

where ('paris')  in (select city customers)        or ('london')  in (select city customers)        or  ('dublin')  in (select city customers) or ....

your second select redundant, , can "flip" in condition.

so equivalent of query is:

select * customers city in ('paris','london', 'dublin', 'venice')

update.

based on logic you've disclosed in comments, query should like:

select * customers exists(select top 1 * europe city in ('paris','london', 'dublin', 'venice'))

exactly stated: if exists @ least 1 of city in ('paris','london', 'dublin', 'venice') in europe customers selected, else nothing selected.

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...
