SQLWays changes FOR LOOP REVERSE statement to WHILE statement. Before WHILE statement SQLWays declares INT variable and sets it upper value of loop range. This variable is decremented by 1 in WHILE statement on each iteration. WHILE loop will work till this variable more or equal when lower value of loop range.

Oracle:

BEGIN 
<<label_name>> 
FOR i IN REVERSE 2 .. 5 LOOP 
insert into dept2(deptno) values(i); 
END LOOP label_name; 
END ;

HiRDB:

CREATE PROCEDURE for_loop() 
LANGUAGE SQL 
BEGIN 
 DECLARE i INT; 
 SET i = 5; 
label_name: 
 WHILE (i >= 2) DO 
    insert into dept2(deptno) values(i); 
    SET i = i-1; 
 END WHILE label_name; 
 END;
 END_PROC
