I recently came across a requirement where the user had to list the details of TOP 5 rows that matched a particular critera, but also had to list the total no rows that matched that criteria.
Here's how it can be solved. I am using the Customers table of the Northwind database:
SELECT TOP 5 CustomerID, CompanyName,
COUNT(*) OVER () AS TotalSimilarTitles
FROM Northwind.dbo.Customers
WHERE ContactTitle = 'Owner'
In the query over here, I list the TOP 5 Customers who have the ContactTitle as 'Owner'. The query also counts the total number of Customers that have the ContactTitle as 'Owner'
