The patch adds parsing for multi-column `DROP COLUMN` in Snowflake, but it introduces a new `AlterTableOperation::DropColumns` enum variant without updating all enum consumers (notably span handling in `src/ast/spans.rs`, which is exhaustive in this codebase). That likely breaks compilation, so it does not satisfy the task end-to-end.
Code Review
The patch is directionally close (dialect-gated Snowflake support and tests), but it likely does not satisfy the intended change safely because it introduces a new AST variant (`DropColumns`) instead of extending `DropColumn`, creating high risk of missing match updates and unnecessary API complexity.
The patch adds `AlterTableOperation::DropColumns` and returns it from parser logic, but only updates `fmt::Display` in this diff. Introducing a new enum variant typically requires updating all exhaustive matches (spans/visitors/etc.); missing updates can cause compile-time failures or runtime handling gaps.
Using a separate `DropColumns` variant for the same SQL operation increases API surface and branching. A single `DropColumn` variant with `column_names: Vec<Ident>` is cleaner and avoids compatibility churn for consumers matching on `AlterTableOperation`.
