sql - From a list of numbers I want to get those ids that are not present in the table -


i have list of ids want check if in employee table. want display not in table.

select * employee; employeeid|firstname|lastname 1         | john    | doe 2         | jane    | doe

when run sql statement below hoping ids not present in employee table.

select '1', '2, '3', '4' "x1"from  employee x1 not in (select employeeid employee);

you need transform numbers subquery, select ones not exists in table:

with t ( select 1 x1 dual union select 2 x1 dual union select 3 x1 dual ) select x1 t x1 not in (select employeeid employee)

if have big list of ids , perform more complex queries, might worth looking creating temporary table store them, use temporary table instead of subquery suggested.

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...
