Why only some users get the error: “Connection is busy with results for another command”

Question

I have a Delphi Application that is connected to a SQL Server db using SDAC component from DevArt, we have 200 installations of the software and only to a customer, with some us

Answer 1

@ienax_ridens, I recently encountered the same problem using the same tools (Delphi and Devart-SDAC). In my case one specific query giving two results sets. My TMSQuery was

If Condition= 1 
begin
 Select * from #TempTable1
end else 
begin
  -- Some more stuff
  Insert INTO #TempTable2
 --
 --
End
Select * from TempTable1 -- here is the problem

so in case of Condition = 1 it was giving two results sets and causing "Connection is busy with results for another command"

I hope this helps you.
