Sergey Nuyanzin commented on FLINK-31102: ----------------------------------------- Thanks, it already looks better however there is still room for improvements 1. spark link still contains {{array_size}} in its name which is not related to this issue 2. {quote}An ARRAY. If value is NULL, the result is NULL. {quote} what is {{value}} here? 3. just a nit comment {quote}postgresql https://w3resource.com/PostgreSQL/postgresql_array_remove-function.php {quote} it's better to refer to official documentation like https://www.postgresql.org/docs/12/functions-array.html#ARRAY-FUNCTIONS-TABLE rather than 3-rd party > Add ARRAY_REMOVE supported in SQL & Table API > --------------------------------------------- > > Key: FLINK-31102 > URL: https://issues.apache.org/jira/browse/FLINK-31102 > Project: Flink > Issue Type: Sub-task > Components: Table SQL / Planner > Affects Versions: 1.18.0 > Reporter: jackylau > Priority: Major > Labels: pull-request-available > Fix For: 1.18.0 > > > Remove all elements that equal to element from array. > Syntax: > array_remove(array, needle) > Arguments: > array: An ARRAY to be handled. > Returns: > An ARRAY.
