Initializing Nested Table

Question

I declared a nested table based on a record type. How do I initialize it using a constructor ?
For e.g. ,
Declare
Type Rec Is Record(num Number, chr Char(10)) ;
Type Tab Is Table Of Rec ;
Tab1 Tab := Tab??

Answer 1

I want Tab1(1).num = 1 and Tab1(1).chr = 'A'..how can this be done through the constructor?
If you want to do this with PL/SQL assignment then you don't want a table of RECORDs. That's for SELECT statements. Try this:
CREATE OR REPLACE TYPE my_rec IS OBJECT (num number, chr VARCHAR2(1));
DECLARE
  TYPE tab IS TABLE OF my_rec;
  tab1 tab;
BEGIN
  tab1 := tab();
  tab1.extend;
  tab1(1)  := my_rec(1, 'A');
END;
