So now we have to just start the capturing and wait for the query to be done from the application to the server. What I did over here, I put the filter TDS and that means that we’re going to be filtering the TDS related traffic. After that, we’re going to sniff the traffic, sniff these particular queries using the TDS traffic. Well, we could just click on the icon, and that is also an option. What we’re going to do, we will open up Wireshark over here, just let me do that very quickly. Right now I’m going to switch to another machine, which is a SQL server itself. That’s going to be a part of our demonstration right now. You are able to see that it actually runs in a clear text and we are able to see it’s content. My job would be to sniff and spoof the query that is done by the application to the server.

Now, I’m going to refresh the logins, where you are able to see that we have regular logins here, nothing really suspicious. So very regular query that the applications do. There is actually some kind of information that I’m able to grab here, so I’m going to refresh that. When I’m executing this query, you can see that what I’m getting, actually is the regular table. What I have over here is a regular query, I’m using the CQURE database and I’m doing: “SELECT custid, company name, contact name” etc. This is the client simulating the application. At this point the fix is deployed to approximately 10% of our production capacity, with expected completion by Monday May 21st.First of all, I will show you the environment. We are working as quickly as wise/safe to deploy, validate, the fix. This is why we are able to fix the issue with a SQL DB side change. Our immediate fix is to ensure the SQL DB acts as if it does not have the added functionality, so the SqlClient side bug in 4.7.2 is not encountered. SQL DB is the first to get the latest SQL changes, and recently deployed the added functionality. This only happens if connected to a SQL server that has support for the added functionality as well. SQL rejects those with the error messages seen in this thread. NET Framework 4.7.2 such that in some circumstances (related to MARS) SqlClient incorrectly thinks the added functionality is in use and sends invalid requests to SQL. These improvements involve changes to both SqlClient and SQL server side. These improvements expand the set of operations that can be done in Always Encrypted, however they are not yet ready for applications to use. The issues is due to improvements to the Always Encrypted functionality in SQL. I next want to explain what happened and how Microsoft is fixing it in more detail. I first want to apologize for this incident and the impact on users of. My name is Peter Carlin and I work in the SQL Server team. NET 4.7.2 on my Windcomputer, and the error started up again. The SQL generated by the EF query above runs fine in SSMS.Įdit : I have confirmed that this is specifically caused by. If I remove the join against db.GetEventsForPerson, the query runs.

Join e in db.GetEventsForPerson(personnelId) on fs.Event_Id equals e.Event_Id

Var query = from fs in db.ViewWithInformation I updated the computer to Windwith no other change, and I started getting the error above.

I verified that the same code executes without a problem on another computer using Windows 10 1709. HandleNonSuccessAndDebuggerNotification(Task Previous location where exception was thrown - at `2.InnerInvoke()Īt .Execute() - End of stack trace from Message: The incoming tabular data stream (TDS) remote procedure call Since updating Windows 10 to 1803, I have begun receiving this error anytime I run an EF query that joins against a table-valued function that takes in a scalar parameter.
