Before:

owflake', write='duckdb')[0])"

[georgesittas]

Why do we repeat this pattern N times, one for every table? Just one suffices right?

[georgesittas]

What does generation look like when pretty=True? Since we made the effort of pretty-formatting the other clauses (RENAME, etc), let's do it for this one as well so that the output is consistent.

[georgesittas]

Why are we using _parse_primary() here? Should this be _parse_string()? What if the user supplies a placeholder / parameter, is that handled?
