Oracle procedure within package with alter table throws ORA-01031:insufficient privileges -


i insufficient privileges error when executing procedure inside package, though appropriate access has been granted.

create or replace package developer.ddl_packs procedure disbcons   begin      execute immediate 'alter table tester.address disable constraint pk4';   end; end;  grant alter on tester.address developer;  exec developer.ddl.disbcons

edit: tried adding authid definer in package header. still ora-01031:insufficient privileges error when executed developer. user

execution works if add authid current_user , execute same developer user. not understand why oracle not consider relevant access when executed authid definer

@vivek can add authid definer/current_user within package specification only, think work after that, below package specification should be: 

create or replace package developer.ddl_packs authid current_user     procedure disbcons;  end;

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() .
