Hi thanks for your information and explanation..
To answer your doubt, below explain the rational
The logic for TOTAL_XXX
for instance, I've picked only below data to explain the rational
Account_id            Paying_account             Parent_account        status
3995313               3995313                    3995313                Active
3996786               3995313                    3995313                Deactivated
4008375               3995313                    3995313                Active
Showing accounts relations, status, PR\NPR, and hierarchy we have
Account 3995313 (PR, Active)
    - Account 3996786  (NPR, Deactive)
    - Account 4008375  (NPR,   Active)
TOTAL_PR_ACCOUNTS_A   - Sum of all accounts of the structure that are PR and in sates considered Active.
                        The TOP account is not included in the sum, only TOP account childs
For account 3995313 the TOTAL_PR_ACCOUNTS_A is 0 (Based on the definiton, to calculate TOTAL_PR_ACCOUNTS_A, we need go throught the entire structure for that
                                                  account. In this case, we have 3995313, 3996786 and 4008375. Now we go the this three account one by one
                                           first is 3995313, this account is a TOP account in the entire structure, so is not included in the sum.
                                           second is 3996786, this account is not a TOP account therefore should be included in the sum, however this account is NPR and Deactive, so is disqualify.
                                                 third is 4008375, this account is not a TOP account and is active account therefore should be included in the sum, however this account is NPR so is disqualify.)
For account 3996786 the TOTAL_PR_ACCOUNTS_A is 0 ( the definiton is exactly same as the above)
For account 4008375 the TOTAL_PR_ACCOUNTS_A is 0 ( the definiton is exactly same as the above)
For account 3995313 the TOTAL_NPR_ACCOUNTS_A is 1 (Based on the definiton, to calculate TOTAL_NPR_ACCOUNTS_A, we need go throught the entire structure for that
                                                  account. In this case, we have 3995313, 3996786 and 4008375. Now we go the this three account one by
                                                  first is 3995313, this account is a TOP account in the entire structure, so is not included in the sum.
                                                  second is 3996786, this account is not a TOP account and is NPR therefore should be included in the sum, however this account is Deactive, so is disqualify. 
                                                  third is 4008375, this account is not a TOP account and is active and NPR account therefore should be included in the sum, so is disqualify.)
For account 3996786 the TOTAL_PR_ACCOUNTS_A is 1 ( the definiton is exactly same as the above)
For account 4008375 the TOTAL_PR_ACCOUNTS_A is 1 ( the definiton is exactly same as the above)After execute the code as provided, seems the result was correct but I need more times to verify as I have a milions of records in the DB.
I tried to modify the code to have better performance , but failed to process, Appreciate any help :)
