Good morning Bruno. I think you can use this here: 

select FLOOR(RAND() * 99999)

Or rather: 

BEGIN


DECLARE valorRand bigint;
        set valorRand = select FLOOR(RAND() * 99999);
        if exists (select * from tabela where coluna = valorRand) then
            call meuRandon();
        end if

        return valorRand;

There you have to see how many times this can be repeated.
