sql server - Cannot use a derived table in WHERE subquery -


why can't use d in subquery?

select *  dbo.orders d (select count(*)         d) = 11;

that's not valid syntax... if was, you'd no results unless there 11 rows in orders table.

i'm guessing you're looking following...

with      cte_ordercount (         select              *,             ordercount = count(*) on (partition o.customerid)                      dbo.orders o         ) select      *      cte_ordercount oc      oc.ordercount = 11;

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
