AS Keyword added by default even if not specified on original SQL statement

[Luigi6821]

Hi all,
I am writing you after @TylerBrinks suggested me to open a discussion on the issue mentioned in title.
Basically I am using the C# porting version of Rust one (thanks Tyler) using the Generic dialect in an Oracle
scenario. I know that is not the perfect usage but what happens is that when I parse a SQL statement that do not
have the AS clause specified the dialect automatically add it which causing Oracle error when trying to execute it.
I have tried to create a new dialect for Oracle but I didn't find a way (at least in the c# version) where to override
the default AS clause inserted. I proposed @TylerBrinks some changes to his porting code but he objected that was better to open a discussion here on this topic.
Please I am open to any solution like:
1- Write a new Oracle dialect class giving me the possibility to override the default AS clause
2- Remove default AS clause

Thanks in advance
Regards
Luigi
