> parameter markers not blocked in DDL

>                 Key: SPARK-42623
>                 URL: https://issues.apache.org/jira/browse/SPARK-42623
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 3.4.0
>            Reporter: Serge Rielau
>            Priority: Major
>
> The parameterized query code does not block DDL statements from referencing parameter markers.
> E.g. a 
>  
> {code:java}
> scala> spark.sql(sqlText = "CREATE VIEW v1 AS SELECT current_timestamp() + :later as stamp, :x * :x AS square", args = Map("later" -> "INTERVAL'3' HOUR", "x" -> "15.0")).show()
> ++
> ||
> ++
> ++
> {code}
> It appears we have some protection that fails us when the view is invoked:
>  
> {code:java}
> scala> spark.sql(sqlText = "SELECT * FROM v1", args = Map("later" -> "INTERVAL'3' HOUR", "x" -> "15.0")).show()
> org.apache.spark.sql.AnalysisException: [UNBOUND_SQL_PARAMETER] Found the unbound parameter: `later`. Please, fix `args` and provide a mapping of the parameter to a SQL literal.; line 1 pos 29
> {code}
> Right now I think affected are:
> * DEFAULT definition
> * VIEW definition
> but any other future standard expression popping up is at risk, such as SQL Functions, or GENERATED COLUMN.
> CREATE TABLE AS is debatable, since it it executes the query at definition only.
> For simplicity I propose to block the feature from ANY DDL statement (CREATE, ALTER).
