[TECH DEBT] Extracting fields from query with *

[JCZuurmond]

Let's say a user wants to visualize a table from the following query: SELECT * FROM table. What do we do in such a case?

Options:

• raise an error with please specify explicit columns message

See extracting fields added in #111

@nfx : I am leaning towards logging a warning to user about the * and then trying to create a table with which ever columns are present next to the *. If there is only a * it will be an empty table.

Without database connection it will be impossible to infer the columns. Moreover, I want to nudge users to avoid using the *
