Hadoop/Hive - Split a single row into multiple rows

Question

I\'m trying to find a way to split a row in Hive into multiple rows based on a delimited column. For instance taking a result set:

ID1  Subs
1     1, 2
2            


        

Answer 1

Try this wording

SELECT ID1, Sub
FROM tableName lateral view explode(split(Subs,',')) Subs AS Sub
