sql - Get section from query -


say have table of 1 million video game highscores, integer column score. when user asks top 50 scores, select * highscores order score desc limit 50. simple. if user asks 51 through 100th scores? select top 100 , then, in program interfacing database, ignore first 50 rows; wasteful. , if asked 200000th through 200100th rows? inefficiency worse.

in sql server (2008+)

you can use row_number() range of rows 

with topscores (  select *,row_number() over(order score desc) rownum  highscores   ) select * topscores (rownum between 1 , 100) -- or rownum between 101 , 200

or use dense_rank() consider games same score same order -- below

with topscores (   select *,dense_rank() over(order score desc) scoreorder  highscores   ) select * topscores (scoreorder between 1 , 100) -- or scoreorder between 101 , 200

in sql server 2012 +

you can use offset fetch clause (but not consider games same score 1 order) example high scores rows 101 200

select * highscores order score desc offset 100 rows fetch next 100 rows only;

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
