I am trying to search for specific string pattern using regular expression using GSQL. It seems the best way is to define a UDF. Is there an example for doing so?
The only post I found relevant is the following where Richard Henderson was planning to blog about it.
Our published UDF library (the community one) has a regex searcher in it. I’d forgotten about that blog. Sorry about that. I have used the code in projects and it works well.
Concat should work into a variable assignment, though there can be some tricks needed. I’ll give it a go, and get back here.
