> In expression not compatible with EqualTo Expression
> ----------------------------------------------------

> Key: SPARK-43491
> URL: https://issues.apache.org/jira/browse/SPARK-43491
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.1
> Reporter: KuijianLiu
> Priority: Minor

> The query results of Spark SQL 3.1.1 and Hive SQL 3.1.0 are inconsistent
> with same sql. Spark SQL calculates `{{{}0 in ('00')`{}}} as false, which act
> different from `{{{}=`{}}} keyword, but Hive calculates true. Hive is
> compatible with the `{{{}in`{}}} keyword in 3.1.0, but SparkSQL does not.
> It's better when dataTypes of elements in `{{{}In`{}}} expression are the
> same, it should behaviour as same as BinaryComparison like ` {{{}EqualTo`{}}}.
> Test SQL:
> {code:java}
> scala> spark.sql("select 1 as test where 0 = '00'").show
> +----+
> |test|
> +----+
> | 1|
> +----+
> scala> spark.sql("select 1 as test where 0 in ('00')").show
> +----+
> |test|
> +----+
> +----+{code}
