-------------------------------------
Summary: Remove REGEX Column Feature
Key: HIVE-23176
URL: https://issues.apache.org/jira/browse/HIVE-23176
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Remove the Hive feature: REGEX Column.
Hive has this interesting feature for doing REGEX to SELECT multiple columns.
This needs to go. It is not SQL standard and as currently implemented, it is
impossible to determine if a column identifier is a REGEX or the actual name of
the column. If a column name is enclosed in back ticks then any UTF-8
character is a valid table name.
