I have a table similar to the following: REL_Aid_To_AttributeValue: ID AttributeValueID 101 1319 101

  • 0

I have a table similar to the following:

REL_Aid_To_AttributeValue:
ID    AttributeValueID
101   1319
101   1320
101   1344
101   1345
102   1319
102   1320
102   1321
102   1336
103   1320
103   1336

I have another table that groups these AttributeValueIDs by type:

TBL_AttributeValues:
AttributeValueID    AttributeTypeID
1319                1
1320                1
1321                1
1336                2
1344                3 
1345                3

I have a third table that gives information about each ID from the first table:

TBL_Aids:
ID     Title                Author       etc.
101    Aid About Spiders    John Doe
102    Aid About Mites      Jane Doe 
103    Aid About Beetles    Joe Schmo

I would like to return results of IDs (and information about them, like the Title, Author, etc.) that contain ONLY AttributeValueIDs 1319 OR (inclusive) 1320, within AttributeTypeID=1. So I would hope to return 101 because it only has 1319 and 1320 for AttributeType 1, and also 103 because it has only 1320 for AttributeType 1. I would not want to return 102 because although it has 1319 and 1320, it also has 1321, which is of AttributeType 1 as well.

I tried the following:

SELECT a.ID, a.Title, c.AttributeTypeID, 
COUNT(b.AttributeValueID)AS Total
FROM TBL_Aids as a,
REL_Aid_To_AttributeValue as b,
TBL_AttributeValues as c
WHERE a.ID=b.AidID
AND b.AttributeValueID=c.ID
AND a.Status=2
AND AttributeTypeID=1
AND (b.AttributeValueID=1319
OR b.AttributeValueID=1320)
GROUP BY a.ID, a.Title,
c.AttributeTypeID
HAVING COUNT(b.AttributeValueID) <= 2

But it still returns 102 as a result, because it has already limited by 1319 and 1320 and is counting that total instead of the overall total of AttributeValueIDs for Type 1. Do I need some sort of subquery to accomplish this? Any help would be appreciated! Thank you so much.
