The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Classic ASP:  Error using a "while Loop" within a "while Loop" for a DB result set

Asked by speedygonzalez in Active Server Pages (ASP), VB Script

Tags:

Hello,
      I am creating a content management system for a website.
      This content management system allows dynamic_elements to be created, which are stored within a db table called "dynamic_Element".
I have various types of dynamic elements, such as "Main Heading", "Sub Headings", "Paragraph's", "Hyperlinks", "Images", and "bullet point lists".

All content are stored in the "dynamic_element" table except from "Bullet_point's" which have a seperate table "bullet_point"
Therefore for a bullet point, one dynamic_element is created, and for this one dynamic_element is has many bullet_points.

I execute a query as follows to return the results

"SELECT dynamic_element.*, bullet_point.* from dynamic_element LEFT OUTER JOIN bullet_point on dynamic_element.dynamic_Element_Key = bullet_point.bullet_Point_List_Key where dynamic_element.page_Key =3 order by order_In_Page asc, bullet_point.bullet_Point_Key asc;"

My result set is returned as per attached excel file "query-result.xls" (view this file for results).

I then loop through the result set in my web_page, and for dynamic_element_type of 4 (bullet_point_list) i then try to loop though all the ullet_points relating to this dynamic_element, however I recieve an error as follows:

Script error detected at line 324.
Source line: while objRS("dynamic_Element_Key") = objRS("bullet_Point_List_Key")
Script details:
314
315 elseif objRS("dynamic_Element_Type_Key") = 4 then
316
317 Response.Write " " & vbCrLf
318 Response.Write " "
319 Response.Write objRS("text")
320 Response.Write "" & vbCrLf
321 Response.Write " " & vbCrLf
322
323
324
325 while objRS("dynamic_Element_Key") = objRS("bullet_Point_List_Key")
326
327
328 Response.Write " " & vbCrLf
329 Response.Write "

"
330 Response.Write objRS("bullet_Point_Text")
331 Response.Write " " & vbCrLf
332 Response.Write " " & vbCrLf
333
334 objRS.MoveNext

-> My source code (without the sql query) is as per the attached code snippet.

Do you know how I can avoid such errors and loop through my bullet_points ok?
Do you possibly see where my code error lies?

Any help would be appreciated.
