php - MYSQL : Between or equal -


why not working if both value same use equal operator. user need select date & to, if user select both same date of & 2017-08-13 should still display dates of 2017-08-13 , unfortunately not working.

select * master_data.speed_of_service  ( trans_time >= '2017-08-13' ,  trans_time <= '2017-08-13')

it work if there interval between dates

if had guess, because trans_time has time component. 1 easy fix extract date:

select ss.* master_data.speed_of_service ss date(trans_time) >= '2017-08-13' , date(trans_time) <= '2017-08-13';

a better solution add 1 day "to" date:

select ss.* master_data.speed_of_service ss trans_time >= '2017-08-13' ,       trans_time < '2017-08-13' + interval 1 day;

this better because still allows use of index.

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
