Good job! Another common report type is a tally of certain objects, often based on a time filter. Take a look:
SELECT COUNT(*) FROM Orders WHERE OrderDate >= '2016-07-01' AND OrderDate < '2016-08-01';
In this query, we count the number of orders placed in July 2016. Note how we used the WHERE clause to get the time limit we're interested in.
Also note that dates in MS SQL Server are always placed inside single quotes and are formatted as YYYY-MM-DD (i.e., year-month-day). This may be a bit counterintuitive in countries that use other date formats, so watch out.
Exercise
Count the number of employees hired in 2013. Name the result NumberOfEmployees.
Stuck? Here's a hint!
Use the HireDate column from the Employees table.
