Basic LOOP Statement

With each iteration of the basic LOOP statement, its statements run and control returns to the top of the loop. The LOOP statement ends when a statement inside the loop transfers control outside the loop or when PL/SQL raises an exception.

Syntax

basic_loop_statement ::=

basic_loop_statement
Description of the illustration basic_loop_statement.gif

See "statement ::=".

Semantics

statement

To prevent an infinite loop, at least one statement must transfer control outside the loop. The statements that can transfer control outside the loop are:

label

A label that identifies basic_LOOP_statement (see "statement ::=" and "label"). CONTINUE, EXIT, and GOTO statements can reference this label.

Labels improve readability, especially when LOOP statements are nested, but only if you ensure that the label ine the END LOOP statement matches a label at the beginning of the same LOOP statement (the compiler does not check).
