> Currently, EXPLAIN command puts an empty line if there is no output for an analyzed plan. For example,
> {code:java}
> sql("CREATE VIEW test AS SELECT 1").explain(true)
> {code}
> produces:
> {code:java}
> == Parsed Logical Plan ==
> 'CreateViewStatement [test], SELECT 1, false, false, PersistedView
> +- 'Project [unresolvedalias(1, None)]
> +- OneRowRelation
> == Analyzed Logical Plan ==
> CreateViewCommand `default`.`test`, SELECT 1, false, false, PersistedView, true
> +- Project [1 AS 1#7]
> +- OneRowRelation
> == Optimized Logical Plan ==
> CreateViewCommand `default`.`test`, SELECT 1, false, false, PersistedView, true
> +- Project [1 AS 1#7]
> +- OneRowRelation
> == Physical Plan ==
> Execute CreateViewCommand
> +- CreateViewCommand `default`.`test`, SELECT 1, false, false, PersistedView, true
> +- Project [1 AS 1#7]
> +- OneRowRelation
