In this example, the short text plan is based on the following statement:

SELECT EXPLANATION ('SELECT GivenName, Surname, OrderDate
FROM GROUPO.Customers JOIN GROUPO.SalesOrders
WHERE CustomerID < 100
ORDER BY OrderDate');

The short text plan reads as follows:

Work[ Sort[ Customers<CustomersKey> JNL SalesOrders<FK_CustomerID_ID> ] ]

The short text plan starts with Work[Sort because the ORDER BY clause causes the entire result set to be sorted. The Customers table is accessed by its primary key index, CustomersKey. An index scan is used to satisfy the search condition because the column Customers.ID is a primary key. The abbreviation JNL indicates that the optimizer chose a merge join to process the join between Customers and SalesOrders. Finally, the SalesOrders table is accessed using the foreign key index FK_CustomerID_ID to find rows where CustomerID is less than 100 in the Customers table.
