-----------------------------------
Summary: Column name with reserved keyword is unescaped when query
includes join on table with mask column is re-written
Key: HIVE-22208
URL: https://issues.apache.org/jira/browse/HIVE-22208
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 3.1.0, 4.0.0
Reporter: Riju Trivedi
Join query involving table with mask column and other having reserved keyword
as column name fails with SemanticException during parsing re-written query :
Original Query :
{code:java}
select a.`date`, b.nm
from sample_keyword a
join sample_mask b
on b.id = a.id;
{code}
Re-written Query :
{code:java}
select a.date, b.nm
from sample_keyword a
join (SELECT `id`, CAST(mask_hash(nm) AS string) AS `nm`,
BLOCK__OFFSET__INSIDE__FILE, INPUT__FILE__NAME, ROW__ID FROM
`default`.`sample_mask` )`b`
on b.id = a.id;
{code}
Re-written query does not have escape quotes for date column which cause
SemanticException while parsing :
{code:java}
org.apache.hadoop.hive.ql.parse.ParseException: line 1:9 cannot recognize input
near 'a' '.' 'date' in selection target
