mysql - erro #1064 - You have an error in your SQL syntax -


i can't create table.

this code:

drop table if exists `monitoreos`;  create table `monitoreos` (   `id` integer not null auto_increment default null,   `fecha` varchar null default null,   `id_cliente` integer null default null,   `id_vehiculo` integer null default null,   `posicion` integer null default null,   `numero_serie` integer null default null,   `numero_alterno` integer null default null,   `profundidad_inicial` varchar null default null,   `horometro_actual` varchar null default null,   `profundidad_actual_exterior` varchar null default null,   `profundidad_actual_interior` varchar null default null,   primary key (`id`) );

and error: 

1064 - have error in sql syntax; check manual corresponds mariadb server version right syntax use near 'null default null,   `id_cliente` integer null default null,   `id_vehiculo` i' @ line 3

nullable , default null defaults, can remove them.

more importantly, need length varchar fields. following works:

create table `monitoreos` (   `id` integer not null auto_increment ,   `fecha` varchar(255),   `id_cliente` integer,   `id_vehiculo` integer,   `posicion` integer,   `numero_serie` integer,   `numero_alterno` integer,   `profundidad_inicial` varchar(255),   `horometro_actual` varchar(255),   `profundidad_actual_exterior` varchar(255),   `profundidad_actual_interior` varchar(255),   primary key (`id`) );

here sql fiddle.

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...

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() .
