---------------------------------
Summary: CTAS with SELECT * and expression creates column names
with prefix
Key: DRILL-2030
URL: https://issues.apache.org/jira/browse/DRILL-2030
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.7.0
Reporter: Aman Sinha
Assignee: Jinfeng Ni
Doing a CTAS with the star column and an expression creates columns that
contain the table prefix 'T||' . Looks like the top project did not strip out
the prefix.
{code}
0: jdbc:drill:zk=local> create table region4 as select *, r_regionkey + 1 from
cp.`tpch/region.parquet`;
+------------+---------------------------+
| Fragment | Number of records written |
+------------+---------------------------+
| 0_0 | 5 |
+------------+---------------------------+
0: jdbc:drill:zk=local> select * from region4;
+-----------------+------------+---------------+------------+
| T2¦¦r_regionkey | T2¦¦r_name | T2¦¦r_comment | EXPR$1 |
+-----------------+------------+---------------+------------+
{code}
The column names are correct if there is a regular column with the star column.
