I need to loop through a large table contains around 20k of rows. I tried using CURSOR and BULK COLLECT but it still takes very long time, around half to complete.
What is an efficient way in PL/SQL to loop through the large data set.

normally looping through 20 k rows will be faster if you simply select them. The result can be manipulated while selecting, or you can manipulate the result in a temporary table or a table variable.
