Thank you much for your contribution and effort!
Are you planing more PRs like this? I ask to time a possible 5.1 release with you which would carry your work.

Please no wild card imports (as requested by @wumpz).
Rest looks great as usual and I would merge immediately when this will have been cleaned up. Thanks!

Please check for ALL wild card imports (in case I have missed to mark one), thanks!

You're welcome and thank you also for your support!

Currently, I don't have a complete overview of Exasol syntax which is not supported by JSqlParser, but my next implementation will be the support of the IMPORT (with subimport as part of select) and EXPORT statements of Exasol.
So a 5.1 release might make sense then.

Will do and sorry - my IDE did that automatically.

there should be a configuration for this (even project specific).

Ok, so I would like to suggest we will wait with 5.1 for this specific stuff and then will aim for a release when this would be ready.
Cheers!
