Why not use T-SQL to generate the queries to be executed?  Then cut and paste the result of this into a text file to be executed using OSQL.

For example,

SELECT DISTINCT

'SET NOCOUNT ON SELECT C. CustomerID, C. CompanyName, C.City, O. OrderDate, O. Freight FROM Customers C INNER JOIN Orders  O  ON C.CustomerID = O.CustomerID WHERE C.CustomerID = '''+C.CustomerId+''''

FROM Customers C

     INNER JOIN

     Orders O ON C.CustomerID = O.CustomerID
