Question

I have a table with field1, field2, field3, … and I need to count the number of items in field1 such that I return all records(field1,filed2,field3,…) that occur 6 times or less in the table.

My SQL code is:

SELECT field1, field2, field3, count(field1) CNT
FROM myTable
WHERE trunc(date)  = tp_date(‘03/22/2011’,’mm/dd/yyyy’)
GROUP BY field1
HAVING COUNT(field1)  <  7;

The output that I am getting from the above code is all records are returned from the table not what I expected? Any help would be appreciated!!

Answer 1

I think you need to use a subquery:

SELECT field1, field2, field3, 
FROM myTable
WHERE trunc(date)  = tp_date(‘03/22/2011’,’mm/dd/yyyy’)
AND field1 in 
   (SELECT field1
    FROM mytable
    GROUP BY field1
    HAVING COUNT(field1)  <  7);
