Code Review

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

The patch is directionally close but likely does not satisfy the intended change fully: key Snowflake behavior (`OVERWRITE` multi-table), round-trip fidelity, and AST consistency are incomplete, so it is unlikely to be accepted as-correct.

4 findings

Snowflake `INSERT OVERWRITE ALL/FIRST` is rejected by parser gate

major

Multi-table parsing is only entered when `!overwrite`, so valid Snowflake forms with `OVERWRITE` do not use the new parser path.

src/parser/mod.rs:17005

Multi-table insert query is not populated in `Insert.source`

major

For multi-table statements, `Insert.source` is set to `None` and query is stored inside `multi_table.source`, which can break existing logic expecting `Insert.source` to contain the source query.

src/parser/mod.rs:17022

Serialization omits `OVERWRITE` for multi-table inserts

major

When `multi_table` is present, Display prints `INSERT` and mode/targets but does not include `OVERWRITE`, so round-tripping loses SQL semantics.

src/ast/dml.rs:189

Parser accepts `ELSE INTO ...` without any `WHEN` branch

minor

Validation only rejects when all of unconditional, conditional, and else are empty, so `ELSE`-only conditional form can slip through despite lacking a WHEN condition.
