Yes, but what are the advantages over SQL?

I did quite a bit of SQL in my last job, and I can't think of a single case where I wish I had a pipeline operator. If I wanted to do something similar to the example on your homepage the simplest way is just to use subqueries.

Here's a rewrite of your query in T-SQL...

------------------------------------------------------

SELECT EMP.Country, EMP.LastName, EMP.FirstName, OD.OrderID, ORD.ShippedDate, OD.SaleAmount

FROM (SELECT TOP 10 T1.OrderID, T1.ORDSUM FROM (SELECT OrderID, SUM(UnitPrice * Quantity * (1 - Discount)) AS SaleAmount FROM "Order Details" GROUP BY OrderID) AS T1 ORDER BY T1.ORDSUM DESC) AS OD

LEFT JOIN Orders AS ORD ON OD.OrderID = ORD.OrderID

LEFT JOIN Employees AS EMP ON ORD.EmployeeID = EMP.EmployeeID

------------------------------------------------------

That's fairly concise, and was quick to bash out. I'd wager it could be made even smaller if I used LINQ instead of SQL. Perhaps your method has some advantages in other types of query? How do you see it?

This is an example where SQL can be written in multiple ways to get the same result. It doesn't matter how many lines SQL contains since its all depends on how the database engine going to execute it. Therefore, pipeSQL's main aim is to make it easier to read and understand the query after couple of days/weeks :) .
That's what comments are for. Plus, I didn't find the PIPESQL syntax particularly easy to parse, of course that's natural for a new language, but in order to encourage adoption it'd be best for you to look to simplify it further.
