Thank you in advance.
RichWe're having the same issue. Our setup is Win 2003 Server IIS and Win 2000
SQL. I've found that the version of MDAC is different on the two machines.
Is your setup also 2 machines? If it is, let me know if your versions of M
DAC differ.
Thanks,

Intermittent SQL Server does not exist or access denied.

ASP.NET application with intermittent returns of 503 errors with the
following message.
System.Data.SqlClient.SqlException: SQL Server does not exist or access
denied. SQL Server does not exist or access denied.
An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of
the exception can be identified using the exception stack trace below.
Servers running Windows 2003 SQL 2000.
This has been a problem for a long time (less than .3% of the time). No
code changes have been made. The only changes was Windows SP1 and post
SP patches on all servers. The patching may have made this issue more
pronounced.
Any suggestions from the experts?
Thanks,
RoxanneWhen they are intermittent they are difficult to track down.
Often those related to network connectivity issues. Have you
checked the event logs on the IIS box - particularly looking
for any network related issues?

Intercept Result

Hi,

I am trying to write a system (Stored Proc, View, CLR Proc, ?), where if you query a specific table and it returns data from only 1 column for the submitted SELECT statement then substitute data obtained from an external web service.

Does anyone have any suggestions about how best to implement this? I have searched through the BOL but nothing directly deals with what I want to do.

Thanks,

Blair

P.S. I am using SQL SERVER 2005 ENT Edition with everything available.

Hi,

I'm not very clear with your question.

For substituting a result, you can use CASE within your SELECT statement.

Assuming Table1 table with Col1 as column, and a scalar valued function CLRFunction() which will call a web service,

SELECT CASE Col1
WHEN 'abc' THEN CLRFunction(1)
WHEN 'def' THEN CLRFunction(2)
END 'Col1'
FROM Table1

Here 'abc' and 'def' are the values stored in Col1 of Table1

Hope this answers for your query, else please explain your requirement with some more detail.

Regards

Babu

Thanks that is exactly what I was looking for. I now know what to do.

Hello...

I think calling a webservie inside a SP is not a very good behavior. You should write your SPs so that they finish as fast as possible. If you try to access an outside resource you never know how long it will take(and a webservice is even worse). You should consider moving this logic into your application. Also you need to access external resources in that function, so you have to declare it as "unsafe" which will also have some implications on security...

Also it will be more complicated to make your app responsive while your code is waiting on the SQL Server. Calling a webservice async is very easy... Calling SQL is a little more work (but still no big deal)
