>                 Key: SPARK-40944
>                 URL: https://issues.apache.org/jira/browse/SPARK-40944
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 3.4.0
>            Reporter: Daniel
>            Priority: Major

> Currently the grammar for each CREATE TABLE column is:
> createOrReplaceTableColType
>     : colName=errorCapturingIdentifier dataType (NOT NULL)? defaultExpression? commentSpec?
>     ;
> This enforces a constraint on the order of: (NOT NULL, DEFAULT value, COMMENT value). We can update the grammar to allow these options in any order instead, to improve usability.
