SQL Server 2019 issue with sp_execute_external_script
I've just installed SQL Server 2019 CTP 3.0 with R Services and enable the spexecuteexternal_script and after restarting my machine I ran the following simple code in SSMS just to test it:
@language = N'R'
, @script = N'cat("Hello world")'
And the result was the expected:
STDOUT message(s) from external script:
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
