Oracle PL/SQL Tutorial » PL SQL Statements » Loop

22. 3. 1. Loops

You may use a loop to run one or more statements multiple times.

There are three types of loops in PL/SQL:

Simple loops Run until you explicitly end the loop
WHILE loops Run until a specified condition occurs
FOR loops Run a predetermined number of times
