Iterative Control: LOOP  Statements

The LOOP statement executes a series of statements multiple times. There are 3 forms of LOOP statements: LOOP, WHILE-LOOP, & FOR-LOOP.

LOOP

The simplest form of the LOOP statement is the basic loop that encloses a series of statements between the keywords LOOP and END LOOP which is as shown:

LOOP
sequence_of_statements
END LOOP;

With each of the iteration of the loop, the series of statements is executed, then the control resumes at the top of the loop. If extra processing is undesirable or impossible, you may use an EXIT statement to complete the loop. You may place one or more EXIT statements wherever inside a loop, but nowhere outside a loop. There are 2 forms of EXIT statements: EXIT and EXIT-WHEN.
