[jira] [Created] (SPARK-23175) Type conversion does not make sense under case like select ’0.1’ = 0

             Summary: Type conversion does not make sense under case like select ’0.1’ = 0
                 Key: SPARK-23175
                 URL: https://issues.apache.org/jira/browse/SPARK-23175
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Shaoquan Zhang


SQL select '0.1' = 0 returns true. The result seems unreasonable.

From the logical plan, the sql is parsed as 'Project [(cast(cast(0.1 as decimal(20,0)) as int) = 0) AS #6]'. The type conversion converts the string to integer, which leads to the unreasonable result.
