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!

How to Create and Update XML column?

Asked by tigriswoods in SQL Server 2005, MS SQL Server, XQuery

Tags:

I like the entire concept of xml columns but I am really new to XML.  I'm trying to start out with a simple case but I can't seem to get it to work.  

What I want to do is to create a column that stores zero to many recommendations, for instance something like this:
<root>
<recommendation>Work hard, play hard</recommendation>
<recommendation>Floss the teeth you want to keep</recommendation>
<recommendation>Wash behind your ears</recommendation>
</root>
I have created a schema collection ( - have I done it correctly ?  - this could be the cause of the problem.  I've had trouble finding good examples for the schema collection).  I've attached this as a code snippet.

Next I created a column called GoodAdvice in my Table (called Table_1)

SET ANSI_NULLS ON
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Table_1](
      [id] [int] IDENTITY(1,1) NOT NULL,
      [AdvisorName] [nchar](80) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
      [GoodAdvice] [xml](CONTENT [dbo].[recommendations]) NULL
) ON [PRIMARY]

(In reality, Table_1 already existed, and I am adding the new GoodAdvice column to it.)

Now.  I have a row that has id and AdvisorName already populated.

id=1, AdvisorName="Doctor Who"

and I want to start putting recommendations from Doctor Who into the table.  What is the right syntax for this?  I've tried to do this in various ways, and most recently tried the following with no success:

UPDATE Table_1
   SET GoodAdvice.modify('insert element  recommendation {Do not quit your day job} as first into (//root)[1]')
   WHERE Table_1.id = 1

I get this error:  XQuery [Table_1.GoodAdvice.modify()]: "}" was expected.



Being new to this is frustrating. What am I doing wrong?
