如何为单个主键插入多行？

INSERT INTO table_name (column1, column2, column3) VALUES
(value1, value2, value3),
(value4, value5, value6),
(value7, value8, value9);

BEGIN TRANSACTION;

FOR i IN 1..100 LOOP
  INSERT INTO table_name (column1, column2, column3) VALUES
  (value1, value2, value3);
END LOOP;

COMMIT;

DECLARE
  CURSOR c_data IS
    SELECT column1, column2, column3 FROM source_table;
BEGIN
  FOR r_data IN c_data LOOP
    INSERT INTO table_name (column1, column2, column3) VALUES
    (r_data.column1, r_data.column2, r_data.column3);
  END LOOP;
  COMMIT;
END;
