Given a table with a (non-distinct) identifier and a value:
| ID | Value |
|----|-------|
| 1 | A |
| 1 | B |
| 1 | C |
| 1 | D |
| 2 | A |
| 2 | B |
| 2 | C |
| 3 | A |
| 3 | B |
How can you select the grouped identifiers, which have values for a given list? (e.g. ('B', 'C'))
This list might also be the result of another query (like SELECT Value from Table1 WHERE ID = '2' to find all IDs which have a superset of values, compared to ID=2 (only ID=1 in this example))
Result
| ID |
|----|
| 1 |
| 2 |
1 and 2 are part of the result, as they have both A and B in their Value-column. 3 is not included, as it is missing C
Thanks to the answer from this question: SQL Select only rows where exact multiple relationships exist I created a query which works for a fixed list. However I need to be able to use the results of another query without changing the query. (And also requires the Access-specific IFF function):
SELECT ID FROM Table1
GROUP BY ID
HAVING SUM(Value NOT IN ('A', 'B')) = 0
AND SUM(IIF(Value='A', 1, 0)) = 1
AND SUM(IIF(Value='B', 1, 0)) = 1
In case it matters: The SQL is run on a Excel-table via VBA and ADODB.
