DuckDB v1.0.0 (https://shell.duckdb.org/) behaves the same as Apache Datafusion. Doesn't consider associativity in expressions with a column reference. ``` duckdb> EXPLAIN SELECT col0 + (1+2) FROM (VALUES (100)); ┌───────────────────────────┐ │ PROJECTION │ │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ │ │ (col0 + 3) │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ COLUMN_DATA_SCAN │ └───────────────────────────┘ duckdb> EXPLAIN SELECT col0 + 1+2 FROM (VALUES (100)); ┌───────────────────────────┐ │ PROJECTION │ │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ │ │ ((col0 + 1) + 2) │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ COLUMN_DATA_SCAN │ └───────────────────────────┘ duckdb> EXPLAIN SELECT (col0 + 1)+2 FROM (VALUES (100)); ┌───────────────────────────┐ │ PROJECTION │ │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ │ │ ((col0 + 1) + 2) │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ COLUMN_DATA_SCAN │ └───────────────────────────┘ duckdb> EXPLAIN SELECT (col0 + (1+3)*7+9)+(2*5+3-4+6) FROM (VALUES (100)); ┌───────────────────────────┐ │ PROJECTION │ │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ │ │ (((col0 + 28) + 9) + 15) │ └─────────────┬─────────────┘ ┌─────────────┴─────────────┐ │ COLUMN_DATA_SCAN │ └───────────────────────────┘ ``` -- This is an automated message from the Apache Git Service.
