TLDR I think implementing this function (perhaps call it `nvl` and add an alias to `ifnull`) would be a good addition. Thank you @guojidan I thought DataFusion already supported the `NVL` function but I guess I was remembering the Nan equivalent of `nanvl`: https://arrow.apache.org/datafusion/user-guide/sql/scalar_functions.html#nanvl So the steps are something like: 1. add function 2. add sqllogictests 3. add doc entries Should be a good feature 🏆 Can you please implement it as a ScalarUDF in https://github.com/apache/arrow-datafusion/tree/main/datafusion/functions/src/core (following the model of `nullif`) rather than adding to `BuiltInFunction`? -- This is an automated message from the Apache Git Service.
