sql - SQLstatements returns different values in MS Access & MSSQL -


i trying write sqlstatement return max value table. works in sql server, microsoft access sorts values based on first number (and not number whole) returning wrong tuple.

select top 1 [currency code], [relational exch_ rate amount] [cronus sverige ab$currency exchange rate] order [relational exch_ rate amount] desc

so correct answer should return: gbp | 1354.xxx

and in access get: hkd | 97.xxx

i have tried 

select [currency code], max([relational exch_ rate amount]) [cronus sverige ab$currency exchange rate]

it works max(columnname), when add [currency code] in front/after returns wrong value.

edit: seems access sorting numerical value letters rather actual numbers. tried find way change - without results. input appreciated.

selecting top 1 after grouping , ordering should want

select top 1 [currency code], max([relational exch_ rate amount]) [cronus sverige ab$currency exchange rate] group [currency code] order max([relational exch_ rate amount]) desc

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...
