[jira] [Updated] (ARROW-10759) [Rust][DataFusion] Implement support
for casting string to date in sql expressions
[ https://issues.apache.org/jira/browse/ARROW-10759?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yordan Pavlov updated ARROW-10759:
----------------------------------
Description:
If DataFusion had support for creating date literals using a cast expression such as
CAST('2019-01-01' AS DATE) this would allow a user-friendly way for direct (and therefore more efficient) comparison of date columns to scalar values (compared to representing dates as strings and then resorting to string comparison).
I already have a basic implementation that works, just have to add some more tests.
