JOIN Queries
The CData ADO.NET Provider for Microsoft Dynamics GP supports standard SQL joins like the following examples.
Inner Join
An inner join selects only rows from both tables that match the join condition:
SELECT Customer.Notes, SalesInvoice.TotalAmount FROM Customer, SalesInvoice WHERE Customer.Id=SalesInvoice.CustomerId
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT Customer.Notes, SalesInvoice.TotalAmount FROM Customers LEFT OUTER JOIN SalesInvoice ON Customer.Id=SalesInvoice.CustomerId
