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!

Triming a field after a " - "

Tags: Microsoft, SQL Server, 2005, SP1, SQL, ie
I need to trim city names off of a description field, because it is not entered in every field.  Nearly all of the city names are preceeded by a " - "  ex. "McDonalds - New York"  All I want is "McDonalds".  I have been looking through the knowledge base, and have some ideas, but I can't seem to get it to work right.  My pronlem in not every field contains a dash, and the lengths of the fields that do contain dashes vary.

Does anyone know of a good example?

I don't want to update the data, just maipulate it for a report.

This will trim it for your report:

select
cityname = left(city, charindex('-', city))
from table
 
02.19.2008 at 10:46AM PST, ID: 20931279

Rank: Master

Then use:

Select myFieldlist
, Case When Patindex('%-%', myField) > 0 Then Left(myField, Patindex('%-%', myField) - 1)
            Else myField
            End As myField
From myTable

You can't just use the Select statements as others have posted because they will throw an error on any city entry without a dash.

Oops, actually, you will get no city value on any city without a dash.

I am withdrwing this question.  We have to go a different route.  Thank you all, and sorry.

Yes, I object.  My solution specifically addressed and answered the question posted.  If the user is attempting to withdraw the question because they are going a different route that shouldn't be a valid reason to not award points for a proper, working answer to the original question.
