    Only found one case: `CREATE TABLE` with `PARTITION BY`. Let me explain 
what I found.
    
    First, `CREATE TABLE` command does not support `bucketSpec`. See 
[code](https://github.com/gatorsmile/spark/blob/24edb5f60f3caf79c6e860905041cd09301589db/sql/core/src/main/scala/org/apache/spark/sql/execution/SparkSqlParser.scala#L901-L903)
    
    Second, `CREATE TABLE AS SELECT` that can generate 
`CreateHiveTableAsSelectLogicalPlan` [does not allow users to specify the 
schema](https://github.com/gatorsmile/spark/blob/24edb5f60f3caf79c6e860905041cd09301589db/sql/core/src/main/scala/org/apache/spark/sql/execution/SparkSqlParser.scala#L984-L989),
 which includes partitionBy columns.
    
    Let me know if anything is still missing. Thanks!
