SQL Query to Select First/Top N records

Here is my code so far:

SELECT WeekNumber, SUM(Hours)
FROM Information
WHERE YEAR = 2011
GROUP BY WeekNumber
ORDER BY WeekNumber DESC

However; I am trying to select either the information for the last week, or the last month. Is there a way to select just the first row, or the first x rows, where those rows contain the hours for that month?

Answer 1

Assuming you’re using SQL Server, use the TOP clause (limit is only for MySQL); e.g.:

SELECT TOP 10 WeekNumber, SUM(Hours)
FROM Information 
WHERE YEAR = 2011
GROUP BY WeekNumber
ORDER BY WeekNumber DESC
