Upgrade SQL Server 2016 R Service (in-database) I am just wondering whether this is doable. I have installed R service (in-database) together with SQL Server 2016 (patched at SP1+ CU1).

I notice R service version is at 3.2.2, which you can run the following script to check

declare @v varchar(100);
exec sp_execute_external_script @language=N'R'
, @script = N'v &lt;- toString(getRversion())'
, @params = N'@v varchar(100) output'
, @v = @v out;

print @v;

-- returns 3.2.2


But I also installed Microsoft R client, and notice its R service engine is versioned at: 3.3.2.

So my question is "does SQL Server R service (in-database) now support R version 3.3.2 ?" if so, how can I upgrade it? if not, I guess I will wait until MS ships the update.

I read MSDN, and in it, it mentions using sqlBindR.exe to do the update, but this tool is available only with Windows R server, which I did not install and I even doubt that if I installed it, whether it would update the in-database R service.
I faced the very same problem (when trying to follow the steps described in Use sqlBindR.exe to Upgrade an Instance of R Services). I could not find any SQLBindR.exe.

A friend of mine pointed out to me, that I had to explicitly install "Microsoft R Server", not as part of the SQL Server install bits and pieces, but as a separate download.

All options about how you can download Microsoft R Server are described in a blog post at MSDN, Run Microsoft R Server for Windows by Heidi Steen.

Download and install was done in some minutes. SQLBindR took some more minutes.
Voilá: Now the following script is showing me, what I was looking for. :-)

declare @v varchar(100);
exec sp_execute_external_script @language=N'R'
, @script = N'v &lt;- toString(getRversion())'
, @params = N'@v varchar(100) output'
, @v = @v out;

print @v;

-- returns 3.3.2
