The Epicor ERP Adapter 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 Customers.CustNum, CustBillTo.BTCustNum FROM Customers, CustBillTo WHERE Customers.CustNum=CustBillTo.CustNum

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

SELECT Customers.CustNum, CustBillTo.BTCustNum FROM Customers LEFT OUTER JOIN CustBillTo ON Customers.CustNum=CustBillTo.CustNum
