Skips the remaining statements in the current loop, causing another loop iteration to be attempted.

Syntax

LOOP

Description

Conditional statements are often used inside a loop to control which statements are executed in each loop iteration. For example, in a loop that processes the rows in an employee table, you might want to increase the monthly salary of non-managers and the annual bonus for managers, all in the same loop.

There can be many different sets of statements in the loop, each with a different combination of conditions dictating whether they should be executed. Sometimes you can be in the middle of a loop, and none of the remaining statements apply. The condition that determines this may be nested a few levels deep. While it would be possible to code the rest of the loop with conditional statements to take this condition into account, often it’s simpler to use a LOOP statement when this condition is encountered. This causes the remaining statements in the loop to be skipped, and the next iteration of the loop to be attempted.
