             Summary: Cannot create view when duplicate columns exist in subquery
                 Key: SPARK-23201
                 URL: https://issues.apache.org/jira/browse/SPARK-23201
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.6.0
            Reporter: Johannes Mayer


I have two tables A(colA, col2, col3), B(colB, col3, col5)

If i join them in a subquery on A.colA = B.colB i can select the non duplicate columns, but i cannot create a view (col3 is duplicate, but not selected)

 
{code:java}
create view testview as select
tmp.colA, tmp.col2, tmp.colB, tmp.col5
from (
select * from A left join B
on (A.colA = B.colB)
)
{code}
 

 

This works:

 
{code:java}
select
tmp.colA, tmp.col2, tmp.colB, tmp.col5
from (
select * from A left join B
on (A.colA = B.colB)
)
{code}
