如何在Oracle中向Collection類型的變數中逐條插入資料

標籤：

這篇文章將要介紹如果需要產生一個新的Collection並且向其中添加資料的方法。

procedure insert_object(d in dept_array, d2 out dept_array) is
begin

  --First way to insert data into a new array.
  SELECT CAST(MULTISET
              (SELECT DNO, name, location FROM department_teststruct) AS
              dept_array)
    INTO l_dept_array
    FROM DUAL;

  --Second to insert data into a new array.
  d2 := dept_array();
  FOR j IN 1 .. d.COUNT LOOP
    d2.EXTEND;
    d2(j) := department_type(d(j).dno, d(j).name, d(j).location);
  END LOOP;

  --Test data
  for j in 1 .. d2.count loop
    --update
    d2(j).location := ‘New Loc2_‘ || j;
    INSERT INTO department_teststruct
    VALUES
      (d2(j).dno || j, d2(j).name, d2(j).location);
  end loop;
end insert_object;
