In this example, you will take input from a user and find the reverse of a number in the PL/SQL program.
For example reverse of the number 1354 is 4531.
declare
no number;
rev number:=0;
remainder number;
begin
no:=&no;
while (no>0)
loop
remainder := mod(no,10);
rev := rev * 10 + remainder;
no := floor(no/10);
end loop;
dbms_output.put_line('reverse of number is '||rev);
end;
/Enter value for no: 1354 old 6: no:=&no; new 6: no:=1354; reverse of number is 4531
