oracle - Copying a row in the same table (within a loop of array of tables) -

-

there great answer @shannonseverance on question

copying row in same table without having type 50+ column names (while changing 2 columns)

that showed how dynamically copy row within table same table (changing pk)

declare r table_name%rowtype; begin select * r table_name pk_id = "original_primary_key"; --  select pk_seq.nextval r.pk_id dual;  -- 11g can use instead: r.pk_id := pk_seq.nextval; r.fk_id := "new_foreign_key"; insert table_name values r; end;

i apply approach within function called each time within array of table names

so can select using execute immediate - how declare 'r'? can replace 'table_name' in code variable passed function?

table(1)="table1";  table(2)="table2";  t 1..table.count loop  copytablecontacts(table(i)); end loop;

in end, have amended function slightly

i build 2 arrays

1 - list of table names user_tab_columns table 2 - each table in array1, build comma delimited list of column names all_tab_columns table

so end 2 arrays (example...)

tablename(1) = 'member' tablename(2) = 'salary'  tablecolumns(1) = 'id, surname, sex, dob' tablecolumns(2) = 'id, currentsal, bonus, grade'

i pass these 2 arrayvalues function , use dynamic sql during looping of tablename() array...

procedure copytablerow(inorigmemno number, innewmemno number, intablename user_tab_columns.table_name%type, intablestring long) selectstring varchar2(32000):=null; newtablestring long:=null; inserttablestring long:=null; sqlresultcount number:=0; begin /*check if there @ least 1 row copy*/ execute immediate 'select count(*) ' || intablename || ' id= ' || inorigmemno sqlresultcount; if sqlresultcount > 0   /*build insert statement each row returned*/   dbms_output.put_line('at least 1 row found on ' || intablename || '(' || sqlresultcount || ')');    newtablestring    := replace(intablestring, 'id', 'replace(id, id,' || innewmemno || ')');   selectstring      := 'select ' || newtablestring || ' ' || intablename || ' id = ' || inorigmemno;   inserttablestring := 'insert ' || intablename || '(' || intablestring || ') (' || selectstring || ')';     end if;

i left insert statement based on table definition , value can execute

this seems work fine , suits current needs

note - works if each table has 1 row copy. next challenge cope of tables returning multiple rows id require copying (which interesting seeing i've painted myself non-cursor corner!)

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.
