Equivalence Reasoning

behavioral

The patch adds multi-table INSERT parsing/printing, but it diverges in core behavior/interface from the intended change: it introduces a new `Statement::MultiInsert` instead of extending existing `Insert` handling, applies parsing in generic `parse_insert` (not Snowflake-specific), and uses generic `Values` parsing rather than explicit Snowflake multi-insert value handling (`DEFAULT` support is likely incomplete/ambiguous). These differences can break expected AST behavior and dialect-specific semantics.

Code Review

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

The patch likely does not satisfy the intended change: it implements a divergent API/AST approach, broadens parser behavior outside Snowflake, and under-specifies Snowflake multi-table INTO VALUES semantics.

4 findings
Introduces new statement kind instead of extending existing Insert AST
major

The intended change is multi-table Snowflake INSERT support within existing `Insert` handling, but the patch adds a new `Statement::MultiInsert` path. This is behaviorally and API-wise divergent and likely mismatches expected parser/serializer contracts.

src/ast/mod.rs:3428
Parser hook is applied globally rather than Snowflake-specific
major

The multi-table branch is added in generic insert parsing (`parse_insert`) whenever `ALL`/`FIRST` follows `INSERT`, so non-Snowflake dialect parsing behavior is changed unexpectedly.

src/parser/mod.rs:17001
INTO VALUES grammar does not model Snowflake DEFAULT token explicitly
major

`parse_multi_insert_into` delegates to generic `parse_values`, and AST stores `Option<Values>`, so Snowflake-specific per-value forms (notably `DEFAULT`) are not explicitly represented/validated as required by the task.

src/parser/mod.rs:17270
Creates parallel insert type hierarchy with duplicated responsibilities
major

Adding `MultiInsert`, `MultiInsertForm`, `MultiInsertInto`, and separate statement handling duplicates existing insert infrastructure, making future parser/AST evolution harder and inconsistent.
