[GitHub] [druid] gianm opened a new issue #10052: Reconcile SQL MV function behavior on SQL arrays

[GitBox <gi...@apache.org>]

gianm opened a new issue #10052:
URL: https://github.com/apache/druid/issues/10052


   The docs say that SQL MV_* functions all work on arrays:
   
   > All 'array' references in the multi-value string function documentation can refer to multi-value string columns or ARRAY literals.
   
   But it isn't true. Many of them (MV_SLICE, MV_CONCAT, others) have signatures that do not accept SQL ARRAY types. We should either make these functions work on SQL ARRAYs, or update the docs to say that they do not.
