Programatically Verifying SQL Syntax

OK, so I'm working on a project that requires the dynamic generation of SQL statements. Now in Visual Studio .NET I'm sure many of you have used that wonderful visual database tool that allows you to magically "verify sql syntax" at the click of a button. It takes a query that looks like this:

"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.EMail, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductId, P.BuyerId FROM Affiliates A, Purchases P WHERE (ProductId > 0) ORDER BY 1"

and transforms it into something that looks like this:

"SELECT A.AFFID, A.UserName, A.Pass, A.FirstName, A.LastName, A.Company, A.Street, A.City, A.State, A.ZIP, A.Country, A.phone, P.Email, A.RecieveEMail, A.SSN, A.JoinDate, A.AffType, P.ProductID, P.BuyerID
FROM Affiliates A CROSS JOIN Purchases P
WHERE (P.ProductID > 0)
ORDER BY A.AFFID"

My question is: is there anything in the .NET platform that would allow me to achieve the same kind of result programatically (i.e. transform standard sql to tsql syntax and verify the syntax of the query at run time)?

Any help would be appreciated! Cheers.No, you have to sit down and start programming.

Having a parser generator available helps, if you find a SQL syntax as LALR.|||I was afraid you would say that.
