# Multiple aggregate functions in HAVING clause

Due to the nature of my query i have records with counts of 3 that would also fit the criteria of having count of 2 and so on. I was wondering is it possible to query 'having count more than x and less than 7' ? How could I write this. Here is my current code.

```GROUP BY meetingID
HAVING COUNT( caseID )<4
```

I'd like something like

```GROUP BY meetingID
HAVING COUNT( caseID )<4 AND >2
```

That way it would only count for exactly 3

## Answers

```GROUP BY meetingID
HAVING COUNT(caseID) < 4 AND COUNT(caseID) > 2
```

There is no need to do two checks, why not just check for count = 3:

```GROUP BY meetingID
HAVING COUNT(caseID) = 3
```

If you want to use the multiple checks, then you can use:

```GROUP BY meetingID
HAVING COUNT(caseID) > 2
AND COUNT(caseID) < 4
```

For your example query, the only possible value greater than 2 and less than 4 is 3, so we simplify:

```GROUP BY meetingID
HAVING COUNT(caseID) = 3
```

In your general case:

```GROUP BY meetingID
HAVING COUNT(caseID) > x AND COUNT(caseID) < 7
```

Or (possibly easier to read?),

```GROUP BY meetingID
HAVING COUNT(caseID) BETWEEN x+1 AND 6
```

Something like this?

```HAVING COUNT(caseID) > 2
AND COUNT(caseID) < 4
```

```SELECT BillingDate,
COUNT(*) AS BillingQty,
SUM(BillingTotal) AS BillingSum
FROM Billings
WHERE BillingDate BETWEEN '2002-05-01' AND '2002-05-31'
GROUP BY BillingDate
HAVING COUNT(*) > 1
AND SUM(BillingTotal) > 100
ORDER BY BillingDate DESC
```

```select CUSTOMER_CODE,nvl(sum(decode(TRANSACTION_TYPE,'D',AMOUNT)),0)) DEBIT,nvl(sum(DECODE(TRANSACTION_TYPE,'C',AMOUNT)),0)) CREDIT,
nvl(sum(decode(TRANSACTION_TYPE,'D',AMOUNT)),0)) - nvl(sum(DECODE(TRANSACTION_TYPE,'C',AMOUNT)),0)) BALANCE from TRANSACTION
GROUP BY CUSTOMER_CODE
having nvl(sum(decode(TRANSACTION_TYPE,'D',AMOUNT)),0)) > 0
AND (nvl(sum(decode(TRANSACTION_TYPE,'D',AMOUNT)),0)) - nvl(sum(DECODE(TRANSACTION_TYPE,'C',AMOUNT)),0))) > 0
```
