Subject [jira] [Updated] (SPARK-29667) implicitly convert mismatched datatypes on right side of "IN" operator
Date Wed, 04 Dec 2019 01:45:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-29667?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hyukjin Kwon updated SPARK-29667:
---------------------------------
    Description: 
Ran into error on this sql
Mismatched columns:

{code}
[(a.`id`:decimal(28,0), db1.table1.`id`:decimal(18,0))] 
{code}

the sql and clause

{code}
      AND   a.id in (select id from db1.table1 where col1 = 1 group by id)
{code}

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?
