Code Review

correctness: 1/4edge case handling: 1/4introduced bug risk: 1/4maintainability idioms: 2/4

The patch partially implements the feature (NOCYCLE and CONNECT_BY_ROOT) but likely does not satisfy the intended hierarchical-query redesign, and it introduces regression risk by removing generic select-item prefix handling.

3 findings
Hierarchical AST model does not match intended flexible clause representation
major

The patch keeps a single `ConnectBy` struct with optional `condition` instead of modeling `START WITH` and `CONNECT BY` as independent clause kinds, so clause ordering and structure are not represented as required by the intended Oracle 21c-aligned change.

src/ast/query.rs:1209
Generic reserved-keyword select-item operator path was removed
major

Previous generic prefix handling in `parse_select_item` was deleted and replaced with a CONNECT_BY_ROOT-specific parser branch. This can break or block other dialect-specific reserved select-item operators that depended on the generic mechanism.

src/parser/mod.rs:17530
Clause-order fidelity is not preserved in AST/display path
major

Because `START WITH` is stored as an optional field on one struct and emitted before `CONNECT BY`, input clause order is normalized rather than represented, which weakens support for order-flexible syntax semantics and round-trip fidelity.
