DescribeQueryCommand

case class DescribeQueryCommand(queryText: String, plan: LogicalPlan) extends DescribeCommandBase with Product with Serializable

Command that looks like

DESCRIBE [QUERY] statement

Parameter 'statement' can be one of the following types : 1. SELECT statements 2. SELECT statements inside set operators (UNION, INTERSECT etc) 3. VALUES statement. 4. TABLE statement. Example : TABLE table_name 5. statements of the form 'FROM table SELECT *' 6. Multi select statements of the following form: select * from (from a select * select *) 7. Common table expressions (CTEs)
