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! |

Asked by NigelRocks in SQL Query Syntax
Experts,
I have a table called "Agent" with a primary key of AgentID. I want to create a foreign key in my "AgentClient" table using a script. This is how I'm attempting to do it:
ALTER TABLE AgentClient
ADD CONSTRAINT fk_AgentID FOREIGN KEY(AgentID)REFERENCES Agent(AgentID)
GO
However I get this error:
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "fk_AgentID". The conflict occurred in database "CCS_Central", table "dbo.Agent", column 'AgentID'.
There is not constraint by that name on either table. What could be the issue?
