The real question is what flavor of sql is supported? Is it just ansi-sql or is it dependent on the data source and its capabilities? Because, for example snowflake and big query have way more nicer sql capabilities than just the basic ansi-sql, and the custom sql in the data source pane is dependent on the source. Here, not sure if prep behaves different?

After connecting to impala custom sql do not work. But impala views and tables can be accessed by prep. Very peculiar. Any work around on this?

I know I'm late but is there a video going into details of this section.
For example like if I'd like to add grant user access to Oracle rather than going into the DB. Could it be done here directly?

Is there a way for Prep to output the SQL of the flow steps itself?
