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!

Index limitations
I'm using SQL Mobile 2005. I have a table with 58000 + rows. When I add an index for a column of type nchar(10) no rows are returned when I do a search on the newly indexed column. Is there some sort of indexing limitation I should be aware of?

and you got rows when there was no index?

Yeah, that's what's throwing me off.

A unique index is an index on a column where each value is unique (the primary key for example)

I know that.

I am asking if thats the type of index you created.

Can you drop the index
make a copy of the database without data
add an index to the new table
export the rows into the new table
drop the old table
and rename the new table  and then select your rows
 
05.01.2008 at 06:50AM PDT, ID: 21478525
Sorry about that, must have had tired eyes. No it's just a standard index. We've actually tried what you suggested with no luck. Last night we split the table into two separate tables and added the index to each and it's working. It was working fine up until we went from around 55,500 rows to 58000+. That's what kind of got us to thinking there may be some limitations to indexing with sql mobile.

I will find out further.

How many bytes is a record?
How many bytes is the table?
How many columns in the index?
How many bytes in the index?
 
05.02.2008 at 08:51AM PDT, ID: 21487644
I'll have to get back to you with the byte counts. One thing we found yesterday was that this may be some sort of issue with Vista. We recreated the index on a machine running xp and everything seems to work fine. When we do the same on a Vista box we get the problem. I'll go ahead and try 3.5 and let you know what happens.

Sorry, we didn't even realize it had anything to do with Vista until yesterday. Had I known I wouldn't just decide not to tell you.

I actually had to go on an appointment so I haven't had a chance to try it yet. I'll probably wait until Monday. Thanks.
