CONTINUE [ label ] [ WHEN boolean-expression ];
If no label is given, the next iteration of the innermost loop is begun. That is, all statements remaining in the loop body are skipped, and control returns to the loop control expression (if any) to determine whether another loop iteration is needed. If label is present, it specifies the label of the loop whose execution will be continued.
WHEN is specified, the next iteration of the
loop is begun only if boolean-expression is
true. Otherwise, control passes to the statement after
CONTINUE can be used with all types of loops; it
is not limited to use with unconditional loops.
LOOP -- some computations EXIT WHEN count > 100; CONTINUE WHEN count < 50; -- some computations for count IN [50 .. 100] END LOOP;
