However, in case > of divide-by-zero, Hive demonstrated a different behavior. > {code} > hive> select 5/0 from tmp2 limit 1; > Total MapReduce jobs = 1 > ... > Total MapReduce CPU Time Spent: 860 msec > OK > Infinity > {code} > The correct behaviour should be Hive returning NULL instead in order to be > consistent w.r.t error handling. (BTW, the same situation is handled > corrected for decimal type.) > MySQL has server modes control the behaviour. By default, NULL is returned. > For instance, > {code} > mysql> select 3/0 from dual; > +------+ > | 3/0 | > +------+ > | NULL | > +------+ > 1 row in set (0.00 sec) > {code} -- This message was sent by Atlassian JIRA (v6.1#6144)
