Pratik DeyandClaude Sonnet 4.6	7b1c063848	feat(python): add type-safe expression builder API (#3150) ... Introduces col(), lit(), func(), and Expr class as alternatives to raw SQL strings in .where() and .select(). Expressions are backed by DataFusion's Expr AST and serialized to SQL for remote table compat. Resolves: - https://github.com/lancedb/lancedb/issues/3044 (python api's) - https://github.com/lancedb/lancedb/issues/3043 (support for filter) - https://github.com/lancedb/lancedb/issues/3045 (support for projection) --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-31 11:32:49 -07:00
Pratik DeyandClaude	d1d720d08a	feat(nodejs): support field/data type input in add_columns() method (#3114) ... Add support for passing field/data type information into add_columns() method, bringing parity with Python bindings. The method now accepts: - AddColumnsSql[] - SQL expressions (existing functionality) - Field - single Arrow field with explicit data type - Field[] - array of Arrow fields with explicit data types - Schema - Arrow schema with explicit data types New columns added via Field/Schema are initialized with null values. All field-based columns must be nullable due to null initialization. Resolves #3107 --------- Signed-off-by: Pratik <pratikrocks.dey11@gmail.com> Co-authored-by: Claude <noreply@anthropic.com>	2026-03-13 12:57:14 -07:00
