The CData Excel Add-In for Sage 300 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 * FROM OEInvoices INNER JOIN OEInvoices_InvoiceDetails ON OEInvoices.InvoiceUniquifier=OEInvoices_InvoiceDetails.InvoiceUniquifier

Left Join

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

SELECT * FROM OEInvoices LEFT JOIN OEInvoices_InvoicePaymentSchedules ON OEInvoices.InvoiceUniquifier=OEInvoices_InvoicePaymentSchedules.InvoiceUniquifier
