starocean999 opened a new pull request, #66967:
URL: https://github.com/apache/doris/pull/66967
Problem Summary:
The bracket array literal `[...]` only accepted `constant` elements at the
grammar level, so expressions such as `CAST(...)` were rejected with a
confusing
parse error. For example, the following query failed with
`missing ']' at '('`, pointing at the first `(` of the first `TIMESTAMPTZ`
cast:
```
SELECT CAST([
CAST('2026-08-18 12:34:56 +08:00' AS TIMESTAMPTZ(6)),
CAST('2026-08-18 04:34:56 +00:00' AS TIMESTAMPTZ(6))
] AS ARRAY<TIMESTAMPTZ>);
```
This PR relaxes the arrayLiteral rule to accept arbitrary expression items
(consistent with ARRAY(...) and Spark semantics), and updates
LogicalPlanBuilder#visitArrayLiteral accordingly
