Query To Get Rows Which Match With All Given Values

Hi all,

I would like have your help about a query.
In fact, I have a query to retrieve the rows for specific ID.
Like that:

SELECT *
FROM TblUser u
WHERE EXISTS

(

SELECT *

FROM TblScore s

WHERE s.FKIDUser = PKIDUser

)

With this query, I retrieve all users for which ones there are some scores.
Now, I need to get only users with specific score.
In the table TblScore, there is a column ScoreValue.
This column contains a value between 1 and 15

I would like to retrieve the users having score equal to 2,4 and 6
I could add a where clause like that: "and scorevalue in (2,4,6)"
But I want only users having these and only these scores, not less, not more.

So if an user has the following scores: 2,4,6,8, I don't want to retrieve it
If an user has the following scores: 2;4, I don't want to retrieve it.
If an user has the following scores: 2,4,6, I want it.

Someboy would have an idea at my problem ?

Thanks in advance
Jerome
