strings

URL: https://issues.apache.org/jira/browse/SPARK-48430
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 4.0.0

Following queries return unexpected results:
{code:java}
select collation(map('a', 'b' collate utf8_binary_lcase)['a']);
select collation(element_at(map('a', 'b' collate utf8_binary_lcase),
'a'));{code}
Both return UTF8_BINARY instead of UTF8_BINARY_LCASE.
