Hi all

I need some help with a sql statement where, I have 50 top pageranks, but it must be 50 unique urls.

I have tried this one.

SELECT distinct TOP 50 urlen, pagerank, Dato, Googleback, Googleindexed, Bingback, Bingindexed, Yahooback, Yahooindexed FROM Sider pagerank order by pagerank desc, urlen

Anyone that has an idea on how to do it.

do you mean this?


SELECT pagerank, Dato, Googleback, Googleindexed, Bingback, Bingindexed, Yahooback, Yahooindexed
FROM
(
SELECT DENSE_RANK() OVER (ORDER BY pagerank desc) AS rnk,urlen, pagerank, Dato, Googleback, Googleindexed, Bingback, Bingindexed, Yahooback, Yahooindexed FROM Sider pagerank 
)t
WHERE rnk<=50

I´m not quite sure, it fails.

'DENSE_RANK' is not a recognized function name.

But I need the 50 highest pageranks, but not the same url twice or more in the list.
I hope this helps.?

are you using SQL Server 2005 or above? try the below and post the result

SELECT @@VERSION

EXEC sp_dbcmptlevel 'your databasename here'
