oracle - Update specific rows in a column -


i have column 82 rows(from table1) , want update 76 rows in different values table(table2). avoiding 6 specific rows(1, 10, 38, 39, 46, 77). leaving these rows null values.

i used cursor save 76 rows table2

cursor my_cur    select * table2

then tried update table1

begin  x in  my_cur loop    update table1    set my_col = x.acct_num    rnum not in ('1', '10', '38', '39', '46', '77'); end loop; end;

but ended updating these rows same value(only 1 acct_num 76 rows).

i want enter different acct_num 76 rows , in same order in table2

i added rownum in both of them have @ least sure rows skip. ideas how it? thanks.

in update query,as loop hence last value of acct_num table1 loop gets updated rows table2.

there must common column join between table1 , table2 use in condition.

begin  x in  my_cur loop    update table1    set my_col = x.acct_num    table1.common_column = x.common_column , rnum not in ('1', '10', '38', '39', '46', '77'); end loop; end;

this additional filter in clause can solve ur query.

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() .
