Wenchen Fan reassigned SPARK-53786:
-----------------------------------
Assignee: Szehon Ho
> Default value should not conflict with special column name
> ----------------------------------------------------------
>
> Key: SPARK-53786
> URL: https://issues.apache.org/jira/browse/SPARK-53786
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Szehon Ho
> Assignee: Szehon Ho
> Priority: Major
> Labels: pull-request-available
>
> The following query:
> CREATE TABLE t (current_timestamp DEFAULT current_timestamp)
>
> fails after SPARK-51786. This is because for making default value DSV2
> expression, it uses the main analyzer to analyze the default value. However,
> default value should not know about other columns when trying to analyze.
