sql - adding missing dates in mysql data set -


i have mysql query this....

   select cast(created_at date) 'created_date', dayname(cast(created_at date)) 'day', sum(order_type_id=1) 'pickup', sum(order_type_id=2) 'delivery'    orders    created_at >= curdate() - interval 7 day    , created_at < curdate()    , order_status_id != 3    group cast(created_at date);

which returns data below

    date   |      day     | pickup | delivery ----------------------------------------------- 2017-08-08 |    tuesday   |  02    |    01     2017-08-09 |   wednesday  |  01    |    01     2017-08-10 |    thursday  |  01    |    00   2017-08-11 |    friday    |  01    |    01    2017-08-13 |    sunday    |  01    |    00   2017-08-14 |    monday    |  01    |    01

what i'm trying summery of delivery orders , pickup orders past 7 days excluding today.

my prob : if closely observe above, you'll notice dont have output 2017-08-12 (saturday) since there no operations done in same date. idea how these empty dates output have below????

    date   |      day     | pickup | delivery ----------------------------------------------- 2017-08-08 |    tuesday   |  02    |    01     2017-08-09 |   wednesday  |  01    |    01     2017-08-10 |    thursday  |  01    |    00   2017-08-11 |    friday    |  01    |    01    2017-08-12 |   saturday   |  00    |    00   2017-08-13 |    sunday    |  01    |    00   2017-08-14 |    monday    |  01    |    01

if have data on days (just not status want on date), can use conditional aggregation:

   select cast(created_at date) created_date,           dayname(cast(created_at date)) day,           sum(order_type_id = 1 , order_status_id <> 3) pickup,           sum(order_type_id = 2 , order_status_id <> 3) delivery    orders    created_at >= curdate() - interval 7 day , created_at < curdate()    group cast(created_at date);

if not case, need table 1 row per date want. simplest method calendar table.

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
