---------------------------------
Summary: Backtick does not work when used with STORED AS ORC
Key: SPARK-29958
URL: https://issues.apache.org/jira/browse/SPARK-29958
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.0
Reporter: Chano Kim
Column name escape back-tick(`) does not work when ORC format is specified on
CREATE TABLE statement.
*This works:*
{code:sql}
spark-sql> CREATE TABLE test01 (`my-column` STRING);
{code}
*This does not work:*
{code:sql}
spark-sql> CREATE TABLE test02 (`my-column` STRING) STORED AS ORC;
Error in query: Column name "my-column" contains invalid character(s). Please
use alias to rename it.;
{code}
>From above example, back-tick is used to escape dash('{{-'}}) character in
>column name. But it does not work when _{{STORED AS ORC}}_ is specified. This
>must be a bug.
