sorry ask such vague question can't pinpoint why code works on pc , on android phone not iphone 4 safari or chrome? checked browser compatibility .includes , navigator.useragent , .getelementbyid .. missing? html: <p id="demo"></p> <button onclick="go()">click me</button> js: var devices = ["android","iphone","ipod","ipad","blackberry","chrome"]; var useragents = navigator.useragent; function detectdevice() { (var = 0; < devices.length; i++) { if (useragents.includes(devices[i])){ return devices[i]; } } } function go(){ var str = detectdevice(); document.getelementbyid("demo").innerhtml = str; } any appreciated.

on sql server configured case-insensitive, group by can have interesting results when [n][var]char column not first group by column. essentially, looks whatever row encounters "first" (where "first" undefined in absence of order): wins grouping. example: select x.[day], x.[name], count(1) [count] ( select 1 [day], 'a' [name] union select 1, 'a' union select 2, 'a' union select 2, 'a' ) x group x.[day], x.[name] which returns, me: day name count ----------- ---- ----------- 1 2 2 2 using min(x.[name]) has no effect, since grouping happened. i can't add order by before group by , illegal; , adding order by after group by defines output order after grouping - still gives a , a . so: there sane way of doing capitalization @ least consistent groupings? (i'll leave day problem of being consistent separate runs) desired output, either: day nam
