Some database engines, such as Microsoft Access or older versions of Oracle, do not work properly with joins between tables specified in a JOIN clause of a SQL statement. Instead, they expect joins to be specified in the WHERE clause. For example, instead of using the following SQL statement for a query joining four tables:
select Products.ProductName,Customers.CompanyName from [Order Details] inner join Orders on [Order Details].OrderID=Orders.OrderID inner join Products on [Order Details].ProductID=Products.ProductID inner join Customers on Orders.CustomerID=Customers.CustomerID
use the following instead:
select Products.ProductName,Customers.CompanyName from Products,[Order Details],Orders,Customers where [Order Details].OrderID=Orders.OrderID and [Order Details].ProductID=Products.ProductID and Orders.CustomerID=Customers.CustomerID
Set the Include Joins in the WHERE Clause setting to True if your database engine requires joins specified in this manner.
