mihailom-db opened a new pull request, #46474: URL: https://github.com/apache/spark/pull/46474
### What changes were proposed in this pull request? Block of syntax CAST(value AS STRING COLLATE collation_name). ### Why are the changes needed? Current state of code allows for calls like CAST(1 AS STRING COLLATE UNICODE). We want to restrict CAST expression to only be able to cast to default collation string, and to only allow COLLATE expression to produce explicitly collated strings. ### Does this PR introduce _any_ user-facing change? Yes. ### How was this patch tested? Test in CollationSuite. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
