When connecting a notebook to an Elasticube, there is no indication what subset of SQL is expected to work
Simple features like setting
Cell 1 = select * from some_table
Cell 2 = select * from Cell1
give errors suggesting the WITH syntax is not permitted, which is a bit of an issue given how heavily notebooks rely on it.
There also seems to be limitations using ORDER/LIMIT in subqueries (which is fairly essential if CTEs arent allowed)
Any real use of Notebooks on Elasticubes seems quite far away without finishing this feature
