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!

Creating crosstab queries in Oracle

Asked by rockmuncher in Oracle Database

Tags: , , ,

I am having extreme difficulty creating even the simplest of crosstab queries in Oracle.

The horizontal data is fed from this query:
  select a.SRVC_CODE, b.BAND_TEXT
    from SRVC_TAILS a, SRVC_BANDS b
  where b.LOW_BANDWIDTH<=a.RX_BURST
     and b.HIGH_BANDWIDTH>=a.rx_burst

which returns data like this:

SRVC_CODE    BAND_TEXT                  
       6735          <64Kbps                        
       6738          <64Kbps                        
       1060            64Kbps                          
       2087            64Kbps                          
       1045            64Kbps                          
       1285            128Kbps-256Kbps                
       2162            128Kbps-256Kbps                


The veritical is fed from this query:
   select a.SRVC_CODE, CLASS_NAME
     from SRVC_TAILS a, SRVC_CLASSES b
  where a.mceetya_class=b.mceetya_class

which returns data like this:

SRVC_CODE     CLASS_NAME              
       6735         Dialup
       6738         Dialup
       1060         ISDN              
       2087         ISDN
       1045         ISDN
       1285         Cable Modem                    
       2162         SDSL                            
 

What I want to get is a crosstab like this:
                                                           128Kbps-
                      <64Kbps         64Kbps     256Kbps
Dialup                  2
ISDN                                        3
Cable Modem                                            1
SDSL                                                        1


I've looked at the documentation on CUBE, ROLLUP, LAG and LEAD and I can't figure it out.
