- CREATE MACRO Statement 11817
- The CREATE MACRO statement defines a named, callable SQL expression as a database schema object. Macros may declare parameters, which can be referenced by its expression. Once a macro is created, it may be called by referencing its name and

- IN Operator 10437
- The IN operator checks containment of the left expression inside the collection on the right hand side (RHS). Supported collections on the RHS are tuples, lists, and maps, as well as subqueries that return a single column. The single-column

For example: SELECT 42 IN (SELECT unnest([32, 42, 52]) AS x); true If the subquery returns more than one column, a Binder Error is thrown: SELECT 42 IN (SELECT unnest([32, 42, 52]) AS x, 'a' AS y); Binder Error: Subquery returns 2 columns - exp... - https://man.mtool.work/duckdb/2.0/sql/expressions/in.html
- TRY Expression 8871
- The TRY expression ensures that errors caused by the input rows in the child (scalar) expression result in NULL for those rows, instead of causing the query to throw an error. The TRY expression was inspired by the TRY_CAST expression . Exa

- PEG Parser 8080
- New Starting with DuckDB 2.0, the PEG parser is the default parser. In earlier versions it was an experimental, opt-in feature enabled with enable_peg_parser() , which is no longer required or available. DuckDB uses a parser based on PEG (
