SELECT 
    tbl_dtl_feature.customer_id, 
    result, 
    COUNT(*) AS expr1 
FROM tbl_dtl_feature 
WHERE tbl_dtl_feature.feature_id = 'F001' 
     AND TRUNC(tbl_dtl_feature.start_datetime) 
     BETWEEN TO_DATE('10/01/2014', 'DD/MM/YYYY') AND TO_DATE('10/01/2014', 'DD/MM/YYYY') 
GROUP BY tbl_dtl_feature.result, tbl_dtl_feature.customer_id 

Мой набор Результат:

CustomerID Result Count

Попробуйте, как это,

SELECT t.customer_id, 
     count(CASE WHEN result = 'Success' THEN 1 END) Count_Success, 
     count(CASE WHEN result = 'Failure' THEN 1 END) Count_Failure 
FROM tbl_dtl_feature t 
WHERE t.feature_id = 'F001' 
AND trunc(t.start_datetime) BETWEEN to_date('10/01/2014', 'DD/MM/YYYY') AND to_date('10/01/2014', 'DD/MM/YYYY') 
GROUP BY t.customer_id;
