### What problem does this PR solve? Document: https://github.com/apache/doris-website/pull/2582 This commit modifies the behavior of the `json_array` function: - The return type is changed from `String` to `JSON` to maintain type consistency across JSON operations. - The function now enforces all arguments to be of `JSON` type. - To ensure compatibility, implicit `to_json` conversion is applied to all arguments when necessary. A new function called `json_array_ignore_null` has also been added, which is almost identical to` json_array` except that it ignores null values. ``` explain select json_array(1, 2, 3, 'abc'); +-------------------------------------------------------------------------+ | Explain String(Nereids Planner) | +-------------------------------------------------------------------------+ | PLAN FRAGMENT 0 | | OUTPUT EXPRS: | | json_array(1, 2, 3, 'abc')[#0] | | PARTITION: UNPARTITIONED | | | | HAS_COLO_PLAN_NODE: false | | | | VRESULT SINK | | MYSQL_PROTOCAL | | | | 0:VUNION(27) | | constant exprs: | | json_array(to_json(1), to_json(2), to_json(3), to_json('abc')) | | | | | | | | ========== STATISTICS ========== | +-------------------------------------------------------------------------+ ``` Related PR: #xxx Problem Summary: ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
