rawsun007 opened a new pull request, #25930: URL: https://github.com/apache/datafusion/pull/25930
## Which issue does this PR close? - None; documentation fix. ## Rationale for this change The `array_distinct` example says `select array_distinct([1, 3, 2, 3, 1, 2, 4])` returns `[1, 2, 3, 4]`. It returns `[1, 3, 2, 4]`: #20364 changed it to keep elements in the order they first appear, matching `array_union` and `array_intersect`, and the example was not updated. ## What changes are included in this PR? The `#[user_doc]` example and description in `set_ops.rs`, the matching code comment, and `scalar_functions.md` regenerated with `./dev/update_function_docs.sh`. Also a sqllogictest case for the order, since every existing `array_distinct` case used input whose sorted and first-seen orders coincide. ## What is the testing strategy for this PR? Ran the example against `datafusion-cli` built from `main`. The new case in `array_distinct.slt` passes; `cargo fmt --check`, `cargo clippy -p datafusion-functions-nested --all-targets -- -D warnings` and `./ci/scripts/doc_prettier_check.sh` pass. ## Are there any user-facing changes? Documentation and a test only. Generated with Claude Code (claude-opus-5-5); I checked the output above. -- This is an automated message from the Apache Git Service.
