Here is a sample data set

I have a query that returns the above table. Note that in each group of six, there WILL be atleast one row that has value 1 in include column. Look at ref: access query needed but not needed.

Also for each group of six, there are three rows that has grade = 3 and 3 rows that has grade = 6. And corresspondingly, the grade 3 and grade 6 have the same quantity in that group.

What I want to do is filter out all the rows that have less then 15 quantity. However, I still want to group them by 6.

I want to remove a "group" that has both quantity < 15 for both grade 3 and 6. From the above data set I wwant the following result:

-----------------------------------------------------------------------------------------
id   nameid   name        score         diff          include     quantity     grade
---------------------------------------------------------------------------------------

14    0003     MA          20            0                0          12          3
15    0003     MA          14            0                0          25          6
16    0003     MA          100           0                1          25          6
17    0003     MA          100           0                0          25          6

So basically if a group of six has include = 1 in any row, and either grade 3 or 6 quantity > 15 then I want the entire group.

"So basically if a group of six has include = 1 in any row, and either grade 3 or 6 quantity > 15 then I want the entire group."

My guess is this query will identify the candidate nameid groups:

SELECT DISTINCT nameid
FROM YourTable
WHERE
    include = 1
    AND quantity > 15
    AND (grade = 3 OR grade = 6);

If I guessed correctly, you can save it as a separate query, or use it as a subquery, and INNER JOIN it to YourTable to limit the rows returned to only those where nameid meets your criteria. It might look close to this untested SELECT statement:

SELECT y.id, y.nameid, y.[name], y.score, y.diff, y.include, y.quantity, y.grade
FROM
    YourTable AS y
    INNER JOIN [
        SELECT DISTINCT nameid
        FROM YourTable
        WHERE
            include = 1
            AND quantity > 15
            AND (grade = 3 OR grade = 6)
        ]. AS q
        ON y.nameid = q.nameid
ORDER BY y.nameid;

Edit: Add an index on nameid if you don't already have one.
