`DESCRIBE` and `SUMMARIZE` Return Empty Tables in Jupyter
The `DESCRIBE` and `SUMMARIZE` statements return an empty table:  
```python
%sql
CREATE OR REPLACE TABLE tbl AS (SELECT 42 AS x);
DESCRIBE tbl;
```  
To work around this, wrap them into a subquery:  
```python
%sql
CREATE OR REPLACE TABLE tbl AS (SELECT 42 AS x);
FROM (DESCRIBE tbl);
```
