I would like to count customer ages beetween 20 and 30, I can only work out how to search for 20+

ELECT CustomerAge, COUNT(*) TotalCount
FROM THIST
Where IncDate between '1 may 09' and '2 may 09'
GROUP BY PatientAge
HAVING COUNT(*) >20
ORDER BY COUNT(*) DESC

Can anyone help!
Thanks

Please post your table DDL with sample data and the expected result.

The query you posted is confusing. You have CustomerAge and PatientAge which is the correct column

I can't see your query working as posted.

You are grouping by patientAge but then referencing CustomerAge in the SELECT without an aggregate function.

Post some sample data and table structure.

You'll get a nice fast statement from someone in 5 mins if you do this.

SELECT CustomerAge, COUNT(*) TotalCount
FROM THIST
GROUP BY PatientAge
HAVING IncDate between '1 may 09' and '2 may 09'
ORDER BY COUNT(*) DESC

having count(*)>20 filters out those customerages where count of records is greater than 20. Do you want to filter out basis count of customers, or customerage ?

Why did you post this?

Event with the S in SELECT it's still wrong.
