--------------------------------------
Yeah Sure!!
Let's assume the following [^table_definitions] and the following [^query]. The
explain ddl output for the query will look like [^explain_ddl_output]
> Explain ddl for debugging

> For debugging query issues, basic details like table schema, statistics,
> partition details, query plans are needed.
> It would be good to have "explain ddl" support, which can generate these
> details. This can help in recreating the schema and planner issues without
> sample data.
