在dolphindb database中，有个代码如下：
t1= table(1 2 3 3 6 as time, 1.1 2.1 3.1 3.1 6.1 as value) t2 = table(5 3 1 as time, 5.1 3.1 1.1 as qty) fj(t1, t2, `time)
fj后的结果如下：
time value t2_time qty 1 1.1 1 1.1 2 2.1 3 3.1 3 3.1 3 3.1 3 3.1 6 6.1 5 5.1
我想得到如下结果：
time value qty 1 1.1 1.1 2 2.1 3 3.1 3.1 3 3.1 3.1 5 5.1 6 6.1
代码应该怎么写？谢谢！
可以用下面代码：
select nullFill(t1.time, t2.time) as time, value, qty from fj(t1, t2, `time) order by nullFill!(t1.time, t2.time)
或者
(select nullFill(t1.time, t2.time) as time, value, qty from fj(t1, t2, `time)).sortBy!(`time)
