>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.4.3
>            Reporter: Jessie Lin
>            Priority: Minor

> 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?
