您好,以下是我执行的SQL:
insert overwrite table bi_tmp.t_tmp_000184_order
select concat(create_time,'123') -- order
from bi_tmp.t_tmp_000189_order
where order is not null
limit 1;
通过Hook得到的字段血缘信息如下:
"columnLineage":[{"expression":["concat(bi_tmp.t_tmp_000189_order.create_time,'123')"],"qualifiedName":"bi_tmp.t_tmp_000184_order.","inputs":[{"qualifiedName":"bi_tmp.t_tmp_000189_order.create_time"}],"name":""}]
可以看到qualifiedName的值为bi_tmp.t_tmp_000184_order.
没有拿到输出表的字段名
如果加入SQL中被注释掉的别名 order ,血缘信息中qualifiedName的值为bi_tmp.t_tmp_000184_order.order
但这并不一定是输出表中真正的物理字段名,只是SQL中的临时别名
请问这个问题之后会进行维护嘛,期待回复!
