### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description We plan to implement all SQL functions in other famous DBs, like MySQL, PG, Trino, CK, Hive, and more. Facilitate the users to migrate to Doris. They're very suitable for newcomers as your first Doris PR. So here's the list. Feel free to comment to pick anyone! If one is picked, I will tick it. ## Part I. Hive - [x] sinh(from Trino), asinh, atanh, acosh (Easy) @ChenMiaoi - [ ] context_ngrams @noixcn - [ ] factorial (Easy) @Czylm - [ ] str_to_map (another map creator) @CookiePieWw - [ ] levenshtein @boluosanlang0330 See the newest Hive document for these functions' explanation. ## Part II. Trino - [ ] regexp_count, regexp_position - [ ] hamming_distance (better with levenshtein together) @boluosanlang0330 - [ ] human_readable_seconds @ChenMiaoi - [ ] timezone_hour, timezone_minute - [ ] GEO FUNCTIONS - [ ] ST_GeomFromKML @Kosthi - [ ] ST_Equals, ST_Relate - [ ] ST_Intersects, ST_Disjoint, ST_Touches @koi2000 - [ ] ST_Crosses, ST_Overlaps - [ ] ARRAY FUNCTIONS - [ ] dot_product @meox3259 - [ ] trim_array @jita1218 - [ ] ngrams @koi2000 - [ ] combinations @delayyyyyyy - [ ] reduce (lambda function) @cypppper - [ ] sort (add the three arguments with lambda functor version) (Hard) - [ ] bool_or, bool_and (aggregate function) @linrrzqqq More tasks is coming... ## Solution **All the guidelines to implement an SQL function are in https://github.com/apache/doris/issues/48201.
