Select Top 5

Hello.
I have a select query that returns a list of records of the following kind:

Field1 Field2 Field3
A 8 NOK
A 7 NOK
A 5 OK
A 4 NOK
A 3 NOK
A 2 NOK
B 10 OK
B 9 NOK
B 8 NOK
B 7 NOK
B 6 NOK
B 5 NOK
.......

Is it possible to return only the top 5 Values of Field2 for each value of
Field1 where Field3 is NOK and ordered by Field2 DESC?

Thanks.

Assuming your query is called myquery then this should return wnat you need

Expand|Select|Wrap|Line Numbers
  1.  
  2. SELECT *
  3. FROM myquery AS X
  4. WHERE (((X.Field2) In (select top 5 field2 
  5.          from myquery 
  6.          where field1 = X.field1 and field3='NOK'
  7.      order by field2 desc)))
  8. ORDER BY X.Field1, X.Field2 DESC;
  9.

Hello. That's almost what i need but i didn't explained correctly my problem.

What i need is to return the top 5 higher values of Field2, not the 5 first records.

What changes do I need to do?

SELECT DISTINCT *
FROM myquery AS X
WHERE (((X.Field2) In (select DISTINCT top 5 field2
from myquery
where field1 = X.field1 and field3='NOK'
order by field2 desc)))
ORDER BY X.Field1, X.Field2 DESC;
