SQL to check list of value against a table column -


i have table items in column logically grouped. need check list of item exists on table or not. need check exact amount of list.

enter image description here

this table structure , if search against list ("rick" , "max), should have group id 2. but, if search "rick" shouldn't result back.

you can use subquery fetch groups , names, using group by on groupid, group names comma separated(ordered) , check input against it.

for example, in mysql.

   select * (select groupid, group_concat(name order name) "concnames"    my_table     group groupid) subquerytable subquerytable.concnames= 'max,rick';

will give you:

------------------ groupid  concnames 2        max,rick

then check parameter against concnames column(your input names should ordered well)

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
