Zheng Shao commented on HIVE-431:
---------------------------------
I guess the information is already in lineage.
I think it's a good idea to keep lineage information away from the core
metadata, especially given that we are going to have column lineage etc.
But we should provide an easy way for users to retrieve the lineage information.
> Auto-add table property "select" to be the select statement that created the

> A syntactic copy of the query that was used to fill a table would often be
> AMAZINGLY useful for figuring out where the data in the table came from.
> I think the best way to implement this would be to automatically add a table
> property which includes the SELECT statement. For partitioned tables, this
> would need to exist for each partition...or perhaps use some canonical name
> like selectquery for unpartitioned tables, plus selectquery_ds=<DATEID> for
> partitioned tables.
> This problem is growing as more and more tables in our database are generated
> by either "root" or by people who are no longer easy to contact.
