Expand description

Information about a SELECT alias for lateral reference support.

Lateral column aliases allow referencing aliases defined earlier in the same SELECT list. This is supported by dialects like DuckDB, BigQuery, and Snowflake.

§Scope Tracking

Each alias tracks the byte offset range of its containing SELECT’s projection. This is used to ensure aliases from CTEs or subqueries don’t leak into outer SELECT scopes.

Fields§

§name: String

The alias name

§definition_end: usize

Byte offset where the alias definition ends

§projection_start: usize

Byte offset where the containing SELECT’s projection starts (after SELECT keyword)

§projection_end: usize

Byte offset where the containing SELECT’s projection ends (before FROM/WHERE/etc.)
