Are there any SQL Validators that can check syntax against multiple database servers?
For example, I might want to check whether a particular query will work against
I'm not aware of any that are that specific, these will check that the statements are valid ansi 92/99/2003...

That will get you 99% of the way there (especially if are only doing CRUD operations)
maybe if you know which reserved words are used by which database you could roll your own simple checker.. see : How to find if a column name is a reserved keyword across various databases
(as already mentioned) If your goal is to create a database agnostic system think about using a third party tool e.g: entityspaces
