LEAVE

Available in: PSQL

Added in: 1.5

Description: LEAVE immediately terminates a WHILE or FOR loop and continues with the first statement after the loop.

Example: 

while (b < 10) do
begin
  insert into Numbers(B) values (:b);
  b = b + 1;
  when any do
  begin
    execute procedure log_error (current_timestamp, 'Error in B loop');
    leave;
  end
end
c = 0;
while (c < 10) do
begin
  ...
  ...
end

If an error occurs during the insert, the event is logged and the loop terminated. The program continues at the line of code reading “c = 0;
