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!

Call .NET (2003) function from MS SQL 2000 User Defined Function (UDF)

Asked by geekboysteves in Microsoft Visual Basic.Net

Tags: , , , ,

It seems obvious that SQL-DMO comes into play.  But before I bite off all that for the first time, is this a reasonable idea?

I have a VB.NET function that RC4-encrypts/decrypts values.

I want to call it from a SQL 2000 UDF as in:

Create Function dbo.udfDecodeSSN
(
@ID BigInt
)
Returns VarChar(9)
As
Return
(
Select
   DoRC4 ( dbo.Employee.SSN ) as SSN  /* Note the function call here */
From
   dbo.Employees
Where
   dbo.Employees.ID = @ID
)

/* Something like that */

DoRC4() is a VB.NET (2003) function.  The password/encryption key is embedded in it and the .dll created from it is required to run the UDF.

So, is that going to work, and if so, could I get a clue as to calling my .NET function from the UDF?

THANKS!
