SQL Get Top 10 records by date

问题:

I have a table full of bugs. The BugTitle is the page erroring and I also capture the error line. I would like to build an SQL Query that selects the top 10 bugs based on bugtitle and error line. I have this query:

SELECT COUNT(BugTitle) AS BugCount, BugTitle, ErrLine 
FROM Bugs 
WHERE BugDate >= DateAdd(Day, -30, DateDiff(Day, 0, GetDate())) 
GROUP BY BugTitle, ErrLine 
ORDER BY BugCount, ErrLine DESC

But I'm not sure if it's correct. I'm pretty sure that my test data only has 1 bug that happens on the same line but that's not showing up with this query. Can anyone help?

To get the top 10 most frequent you probably want to order by the count:

SELECT TOP(10) COUNT(BugTitle) AS BugCount, BugTitle, ErrLine
FROM Bugs
WHERE BugDate >= DateAdd(Day, -30, DateDiff(Day, 0, GetDate()))
GROUP BY BugTitle, ErrLine
ORDER BY COUNT(BugTitle) DESC
