plsql - Aliasing in Bulk Collect giving error of unimplemented feature -

-

the problem statement: user specify name based on have pull names of 2 tables table , extract values tables.i have created pl/sql procedure , since select query can return n number of rows i'm using bulk collect. have created , object based on fields want extract. problem columns common in both tables, if don't use alias ambiguous column error , if use error of unimplemented feature.

here's code:

create or replace type recon_obj_vib  object (recon_table_key number(19) ,recon_chglogattr_idxlst  varchar2(1000 char));  create or replace type recon_tab_vib table of recon_obj_vib;  create or replace procedure nomatchreport_proc(tabledesc in varchar2) l_recon_tab_vib recon_tab_vib := recon_tab_vib(); n integer :=0; out varchar2(2000); tablename1  varchar2(25); tablename2 varchar2(25); tabledesc_without_space varchar2(25); tabledesc_ra varchar2(25);  begin  tabledesc_without_space:=regexp_replace(tabledesc,'\s');  tabledesc_ra:=upper('ra_' || tabledesc_without_space || ' %');  out:= 'select recon_table_name recon_tables recon_table_desc = (:value) , rownum=1 , recon_table_name (:username)';  execute immediate out tablename1 using tabledesc,tabledesc_ra;  out:= 'select recon_table_name recon_tables recon_table_desc = (:value) , rownum=1 , recon_table_name  not (:username)';   execute immediate out tablename2 using tabledesc,tabledesc_ra;   out:='select a.recon_table_key,a.recon_chglogattr_idxlst bulk collect  l_recon_tab_vib ' || tablename1  || ' , ' || tablename2 ||  ' b a.re_key = b.re_key , rownum=1';   execute immediate out l_recon_tab_vib;   in 1..l_recon_tab_vib.count     loop     dbms_output.put_line('recon_table_key '||     l_recon_tab_vib(i).recon_table_key ||' recon_chglogattr_idxlst ' || l_recon_tab_vib(i).recon_chglogattr_idxlst );    end loop; end;

this part:

out:='select a.recon_table_key,a.recon_chglogattr_idxlst bulk collect   l_recon_tab_vib ' || tablename1  || ' , ' || tablename2 ||  ' b a.re_key = b.re_key , rownum=1'; execute immediate out l_recon_tab_vib;

should be:

out:='select a.recon_table_key,a.recon_chglogattr_idxlst '       || tablename1  || ' , ' || tablename2      ||  ' b a.re_key = b.re_key , rownum=1'; execute immediate bulk collect l_recon_tab_vib;

i.e. bulk collect into clause part of calling pl/sql not part of dynamic sql.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
