KB4538495 - FIX: Access violation occurs when you create remote stored procedure with one of the system variable (@@servername, @@servicename) in SQL Server 2019

Applies to: SQL Server 2019 on Windows

Symptoms


Assume that you create a local stored procedure that calls a remote stored procedure on a linked server through an EXECUTE statement in SQL Server 2019. When one of the remote stored procedure parameter values is a system variable (@@servername, @@servicename,...) like in the following example:
create procedure test
as
begin
    execute [myLinkedServer].[myDB].dbo.myproc @@Servername
end
An access violation may occur. Additionally, you may receive an error message that resembles the following:
Msg 596, Level 21, State 1, Line LineNumber
Cannot continue the execution because the session is in the kill state.
Msg 0, Level 20, State 0, Line LineNumber
A severe error occurred on the current command. The results, if any, should be discarded.

Status
