LEAVE
From SQL PL Guide for DB2
LEAVE statement
The LEAVE statement can be used to jump out of a loop or a compound statement.
If the loop or compound statement is nested you should explicit specify the label you want to leave.
Example:
create procedure leave (in var01 integer, out var02 integer)
begin
declare i integer default 0;
my_loop: loop
if i = var01 then
leave my_loop;
else
set i = i + 1;
end if;
end loop;
set var02 = i;
end!
