SQL Server 2019 bug in sp_execute_external_script RRS feed

  • Question

  • I've just installed SQL Server 2019 CTP 3.0 with R Services and enable the sp_execute_external_script and after restarting my machine I ran the following simple code in SSMS just to test it:

    EXEC sp_execute_external_script         

    @language = N'R'

           , @script = N'cat("Hello world")'

    GO


    And the result was the expected:

    STDOUT message(s) from external script: 
    NULL
    Hello world

    Now, when I tried to run again there's no more result. Just a simple:

    Commands completed successfully.

    And no matter what I change in the code it won't work again until I restart my computer but only for the first run.

    I think this is a bug because was running properly on SQL Server CTP 2.x
