boluor opened a new pull request, #3734: URL: https://github.com/apache/doris-website/pull/3734
## Summary `DATE_TRUNC` accepts both argument orders — `(<datetime>, <time_unit>)` and `(<time_unit>, <datetime>)` — but the **time unit must be a string constant**; it cannot be a column or a non-constant expression. Passing a column there fails with `the ... parameter of date_trunc function must be a string constant`. Added that constraint to the `<time_unit>` parameter description on the current/4.x EN and zh pages so the requirement is explicit. Reported in #2673. ## Test plan - [x] Confirmed in FE source (`DateTrunc.checkLegalityBeforeTypeCoercion` requires a string-literal time unit). - [x] Dead-link check passes. - [ ] CI build.
