> The function
> {code:sql}
> from_unixtime(bigint unixtime[, string format]) {code}
> output error if the value of unixtime is NULL and format is 'u'.
>
> This doesn't work:
> {code:sql}
> SELECT FROM_UNIXTIME(NULL, 'u')
> {code}
> {noformat}
> Bad date/time conversion format: u{noformat}
>
> This works:
> {code:sql}
> SELECT FROM_UNIXTIME(NULL, 'yyyy-MM-dd')
> {code}
> {noformat}
> |from_unixtime(null, 'yyyy-mm-dd')|
> |---------------------------------|
> | NULL |
> |---------------------------------|{noformat}
>
> I haven't checked all the possible combinations.
> Other software like Hive handles this correctly.
