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!

I've just googled through tons of possible solutions here, but nothing that fits the bill exactly.  So here it goes:

MSSQL Server with multiple databases:

CUST_2006_JAN
CUST_2006_FEB
CUST_2006_MAR
 ...
CUST_2007_AUG

as well as the database CUST, which is where all current data goes.  It gets automagically moved to a _year_month database after a while by the app.  All databases have the exact same structure, but with different data.

I've got a current app that does all sorts of database queries (read only) on the CUST database, but the problem is that data that is auto-archived into the dated databases is no longer accessible.

I need a way to easily convert a database query such as "SELECT name FROM CUST.dbo.tblPeople where product=2" into a query that will query -ALL- databases.  Something like "SELECT name FROM *.dbo.tblPeople...."

Databases get added over time, so I don't have a master list I can go on.  I can do something like:

   select name from master.dbo.sysdatabases where name like 'CUST%'

...to get the list of databases, but what do I do with it?

All databases reside on the same server.
