oracle - Pl/SQL Looping through the values of a cursor -

- 

  function Total inc (varchar2 in name 2) returns varchar2 total total number (6); Select monthly_inquas from Cursor C1 employee where name = name_in; BEGIN total_value: = 0; C1 LOOP total_value for employee_reck: = total_val + employee_re_mammle_income; End loop; Return all_val; End;   
 In this example, I am being told that we are looping through values, but I do not believe that we are getting through the values ​​why  Employee_rec.monthly_income  required? Also, when I do  employee_reck  on  FETCH , I think they are different from each other. I think they are different from each other.  
  
 
 
 You are looping through the result set in the  record .  
 In other words: Open the cursor  C1    
 for employee_rec  
  in c1 and Perform a fetch on it For each row, assign the Record to a record variable named  employee_rec .  
 Then in the context of  monthly_income , you have to say  employee_rec.monthly_income  on your code and not just  monthly_income  to say < / P> 
 
 When I do a FETCH on employee_reck   
 employee_reck is not a cursor (its one variable) so that you do not get it from it. In this case, get from  C1  is implied by the loop, so there is no clear fact required on your part.

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.
