I have a little problem converting from an access database to the SQL
server
I need to have a highscore that shows the top 10 scores, grouped by
email.
In my access db i had this query:
"SELECT TOP 10 First(users.user_naam) AS FirstOfuser_naam,
First(users.user_voornaam) AS FirstOfuser_voornaam,
Max(scores.score_score) AS MaxOfscore_score FROM users, scores WHERE
scores.score_userid=[users].[user_id] GROUP BY users.user_email ORDER
BY Max(scores.score_score) DESC"
But in SQL Server, First isn't known, and without it, i get:
... is invalid in the select list because it is not contained in either
an aggregate function or the GROUP BY clause
How can i make it show the top 10 scores, but with no duplicates of
email.
ex:
SELECT users.user_naam, users.user_voornaam,scores.score_score,
users.user_email FROM users, scores WHERE scores.score_userid =
users.user_id
this is the query for selecting all
Someone knows a solution?
ThxYou might try substituting MIN (or MAX) for FIRST. This will return the
same result as long as user_naam and user_voornaam values are the same for a
given user_email value.
If user_naam and user_voornaam values differ for a given user_email, you'll
need to specify your requirements for which of those values should be
returned. If you really don't care, MIN/MAX will suffice but the values
might be different than the original Access query.

Hope this helps.

try something like this.
SELECT TOP 10
users.user_naam,
users.user_voornaam,
MAX(scores.score_score) as MaxScore,
users.user_email
FROM users
JOIN scores
ON scores.score_userid = users.user_id
GROUP BY users.user_naam,
users.user_voornaam,
users.user_email
ORDER BY MaxScore DESC
