Collection.extend doubt

Question

hi all...
the way we use collection_name.extend
in the same way can we use tablename%rowtype.extend ???
please help....
in that case how can i do that??

Answer 1

You cannot extend tablename%rowtype, because this is a type, not a collection.
However you can declare a collection of that type, here is a simple example:
CREATE TABLE test132(
  x VARCHAR2(10),
  y NUMBER,
  z char
DECLARE
   TYPE tab_type IS TABLE OF test132%ROWTYPE;
   tab tab_type;
BEGIN
  tab := tab_type();
  tab.EXTEND( 5 );
  FOR i IN 1 .. 5 LOOP
    tab( i ).x := 'x ' || i;
    tab( i ).y := 20 + i;
    tab( i ).z := i;
  END LOOP;
  FOR i IN tab.FIRST .. tab.LAST LOOP
      DBMS_output.put( tab( i ).x );
      DBMS_output.put( '   ' );
      DBMS_output.put( tab( i ).y );
      DBMS_output.put( '   ' );
      DBMS_output.put_line( tab( i ).z );
      INSERT into test132 VALUES tab( i );
  END LOOP;
END;
x 1   21   1
x 2   22   2
x 3   23   3
x 4   24   4
x 5   25   5
SELECT * FROM test132;
X          Y                      Z
x 1        21                     1
x 2        22                     2
x 3        23                     3
x 4        24                     4
x 5        25                     5
