Having read Erland's article
https://www.sqlservergeeks.com/a-tip-about-using-python-for-regular-expressions-in-t-sql-by-erland-sommarskog/
on regular expressions for SQL Server and the advantage of enabling sp_execute_external_script. This works with the version of Anaconda3 that installs with SQL Server 2019. There is an issue on the laptop used here because group policy (via the government policy) demands the use of FIPS. For this reason, installing R or Java will fail (I suspect it doesn't sit well with managed copies of encryption). Anaconda requires many over-rides during installation via Privileged Management Administrator and is installed locally through a painstaking process.
My bigger fear is that if I remove Anaconda3 to install using SQL, it will either fail similarly as did R and Java, or worse, I'll have trouble re-installing the version of Anaconda currently on the machine.
So again, the question is whether or not it is possible to enable sp_execute_external_script on SQL without installing R, Python, or Java. I tried Java and R and both fail to install. The Java and Python are already installed.
