i wanna start sixth line , insert variable 'country' afghanistan , albania , variable 'id' afn , all. how can in pl sql?

declare    v_string   varchar2 (4000)       := '[ quotazioni in euro riferite al 08/08/2017 "" paese,valuta,codice iso,codice uic,quotazione,convenzione di cambio,nota "" afghanistan,afghani,afn,115,80.8402,quantità di valuta per 1 euro albania,lek,all,047,132.275,quantità di valuta per 1 ]';     country    varchar2 (20);    id         varchar2 (5); begin    row       in (select *             (    select regexp_substr (line6,                                             '[^,]+',                                             1,                                             level)                                 fields,                              row_number () on (order rownum) rn                         (select regexp_substr (v_string,                                                     '^.*$',                                                     1,                                                     5,                                                     'm')                                         line6                                 dual)                   connect regexp_substr (v_string,                                             '[^,]+',                                             1,                                             level)                                 not null) pivot (max (fields)                                                 rn                                                 in (1 field_1,                                                    2 field_2,                                                    3 field_3,                                                    4 field_4,                                                    5 field_5,                                                    6 field_6)))    loop       country := row.field_1;       id := row.field_3;    end loop; end; /

your table design not efficient , not data model have here. related records distinct must placed in proper columns , merged single string.

you can achieve shown using regexp_substr split string , pivot convert appropriate fields named columns.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
