--------------------------------------

             Summary: Scalar subquery error
                 Key: SPARK-24085
                 URL: https://issues.apache.org/jira/browse/SPARK-24085
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.0, 2.3.1
            Reporter: Alexey Baturin


Error
{noformat}
SQL Error: java.lang.UnsupportedOperationException: Cannot evaluate expression: scalar-subquery{noformat}
Then query a partitioed table based on a parquet file then filter by partition column by scalar
subquery.

Query to reproduce:
{code:sql}
CREATE TABLE test_prc_bug (
id_value string
)
partitioned by (id_type string)
location '/tmp/test_prc_bug'
stored as parquet;

insert into test_prc_bug values ('1','a');
insert into test_prc_bug values ('2','a');
insert into test_prc_bug values ('3','b');
insert into test_prc_bug values ('4','b');


select * from test_prc_bug
where id_type = (select 'b');
{code}
If table in ORC format it works fine
