Walt, here is the example how you can use joins in ASPRunner 2.1.
Select ID,
OrderDate,
CustomerID,
b.ID as DetailID,
b.Quantity as ProductQuantity
from OrderHeader a
inner join OrderDetail b on
a.ID = b.OrderID
If you like to use joins you need to adjust your SQL query manually on the SQL query tab. Note: it's recommended to use aliases for fields from joined tables to avoid confusion when two from different tables have the same name. Sergey Kornilov
