The CData Cmdlets PowerShell Module for Oracle Fusion Cloud Financials 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 c.InvoiceNumber, o.LineAmount, o.LineType, o.TaxRate FROM Invoices c INNER JOIN InvoicesInvoiceLines o ON c.InvoiceId = o.InvoicesInvoiceId

Left Join

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

 SELECT c.InvoiceNumber, o.LineAmount, o.LineType, o.TaxRate FROM Invoices c LEFT JOIN InvoicesInvoiceLines o ON c.InvoiceId = o.InvoicesInvoiceId
