Hi Drill Team, I am quite new to using Apache Drill, and am enjoying working with it. Great work!! I'll be pleased if you guys can help me with a situation.
I have a scenario where I need to aggregate multiple column values into single row (say, comma separated) which can be done using GROUP_CONCAT function in MySQL or LISTAGG function in Oracle and other relevant functions for other databases. I went through the Drill docs, but couldn't find any such function. I want to know if this can be achieved using any of the built-in functions for Drill or not? And if not, what is the best alternate to get this done (like maybe creating a custom function or something else) I'll really appreciate any sort of help. Thanks in advance. Vivek Maheshwari
