[Quoted] For your convenience, I've tried your examples in our own Query Builder included in Database Workbench, which is based on a third party product.

[Quoted] Yes, no problem whatsoever.
> Can you find WITH?
[Quoted] Parsed and used correctly, did notice a minor GUI error, reported to the vendor.
> Can you find the SAMPLE clause?
[Quoted] Can you give me an example? :)

[Quoted] I'm not sure what you mean by "find" here? You mean being able to select them from a list?

Not tested.

Given that expressions can be entered freely, yes. Parsed correctly as well.

See above.

[Quoted] Parser failed on NAN, this surprised me as well, reported to the vendor.

[Quoted] Parser failed on OF TYPE, this surprised me as well, reported to the vendor.

[Quoted] Parser failed on EMPTY, not surprised anymore, reported to the vendor.

No problem whatsoever.
I'm not dismissing training at all.
