Ruben Q L reassigned CALCITE-4195: ---------------------------------- Assignee: Ruben Q L > Cast from character to character with a different collator must be evaluated > as not monotonic > --------------------------------------------------------------------------------------------- > > Key: CALCITE-4195 > URL: https://issues.apache.org/jira/browse/CALCITE-4195 > Project: Calcite > Issue Type: Bug > Components: core > Affects Versions: 1.24.0 > Reporter: Ruben Q L > Assignee: Ruben Q L > Priority: Minor > Fix For: 1.26.0 > > > Problem related to the feature CALCITE-3951. > A cast operation from a character type to another character type that has a > different collator must be evaluated as not monotonic. Currently this is not > the case. > This has an impact e.g. in SortProjectTransposeRule, since we can incorrectly > transpose a sort after a projection than contains such a cast, and we end up > with a plan that will return a different result than the original one. -- This message was sent by Atlassian Jira (v8.3.4#803005)
