Question

Here is a sample data set
-----------------------------------------------------------------------------------------
id nameid name score diff include quantity grade
---------------------------------------------------------------------------------------
7 0002 MO 10 0 0 25 3
8 0002 MO 18 0 1 25 3
9 0002 MO 20 0 0 25 3
10 0002 MO 14 0 0 17 6
11 0002 MO 100 0 0 17 6
11 0002 MO 100 0 0 17 6
12 0003 MA 10 0 0 12 3
13 0003 MA 18 0 0 12 3
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
12 0004 MB 10 0 0 12 3
13 0004 MB 18 0 1 12 3
14 0004 MB 20 0 0 12 3
15 0004 MB 14 0 0 07 6
16 0004 MB 100 0 1 07 6
17 0004 MB 100 0 0 07 6
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
---------------------------------------------------------------------------------------
7 0002 MO 10 0 0 25 3
8 0002 MO 18 0 1 25 3
9 0002 MO 20 0 0 25 3
10 0002 MO 14 0 0 17 6
11 0002 MO 100 0 0 17 6
11 0002 MO 100 0 0 17 6
12 0003 MA 10 0 0 12 3
13 0003 MA 18 0 0 12 3
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.

Answer 1

"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.
