Code Review

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

The agent patch appears unlikely to satisfy the intended change: it implements ClickHouse INSERT FORMAT via a raw-string tail approach and non-target AST shape, with elevated correctness and regression risk compared to the expected structured parser/AST extension.

4 findings

INSERT FORMAT modeled with wrong AST shape

major

The patch uses `FormatClause` plus `format_data` text on `Insert` instead of a structured input-format clause with parsed values, so behavior diverges from the intended ClickHouse INSERT FORMAT support and round-trip structure.

src/ast/dml.rs:482

Raw tail capture for FORMAT payload is brittle

major

`parse_statement_tail_as_string` consumes tokens until semicolon/EOF and concatenates token strings, bypassing normal SQL AST parsing and creating fragile formatting/semantics behavior.

src/parser/mod.rs:12219

Missing dialect-gated support path required by change

major

The patch does not add the dialect capability hook for insert-format support and instead hard-codes ClickHouse/Generic checks inline, diverging from expected parser design and likely missing integration points.

src/parser/mod.rs:12064

Cross-dialect AST churn from `format_data` field

minor

Adding `format_data` to core `Insert` forces unrelated dialect tests/constructors to carry extra `None` fields, indicating a less idiomatic extension point than a dedicated typed clause.
