14.4. Lambda Expressions
Lambda expressions are written with
x -> x + 1 (x, y) -> x + y x -> regexp_like(x, 'a+') x -> x / x x -> IF(x > 0, x, -x) x -> COALESCE(x, 0) x -> CAST(x AS JSON) x -> x + TRY(1 / 0)
Most SQL expressions can be used in a lambda body, with a few exceptions:
- Subqueries are not supported.
x -> 2 + (SELECT 3)
- Aggregations are not supported.
x -> max(y)
