Hi @andygrove, I did basic `coalesce` function in #1969. Right now i convert every argument to `string` and return a `string` from the function well. But I have a few doubts and need your help there :) 1. What data types do we need to support in `coalesce`? All primitive data types? If yes, can you please point me to a place where this is being done already which i can use it as a reference. 2. Can you please also point me to the TPC-DS benchmarks where `coalesce` is required? I did a quick search but couldn't find any. -- This is an automated message from the Apache Git Service.
