----------------------------------
Summary: implicitly convert mismatched datatypes on right side of
"IN" operator
Key: SPARK-29667
URL: https://issues.apache.org/jira/browse/SPARK-29667
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.3
Environment: spark-2.4.3-bin-dbr-5.5-snapshot-9833d0f
Reporter: Jessie Lin
Ran into error on this sql
Mismatched columns:
[(a.`id`:decimal(28,0), db1.table1.`id`:decimal(18,0))]
the sql and clause
AND a.id in (select id from db1.table1 where col1 = 1 group by id)
Once I cast decimal(18,0) to decimal(28,0) explicitly above, the sql ran just
fine. Can the sql engine cast implicitly in this case?
