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!

Linked servers

Asked by gregoryyoung in MS SQL Server

Tags: server, linked, sql

We have an environment setup here with dupication for development and staging.

Many sprocs exist within the database that use linked servers to get to other sql servers (which are also replicated for the various environments).

example:

in development a select must be issued to a linked server named devsql01.
i.e. [devsql01].[catalog].[table]
in production it must be issued to prodsql01.
i.e. [prodsql01].[catalog].[table]

This causes a huge amount of conflict due to the need to change the physical sprocs in order to change the names of the servers. My thought is to create a DNS based alias (lets call it SQL01) which is dev points to devsql01 and in production points to prodsql01. this way the link servers could use identical naming even though they are in different environments and thus they would not need to have changes to the sprocs

i.e. [Sql01].[Catalog].[Table]

Is there a better way of doing this? perhaps to alias the link server name within sql itself? I have done some quick searches and everything refers to the alias as the server name directly.

Cheers,

Greg
