All functions > WINDOW FUNCTION > ANY_VALUE() OVER ...

Returns an arbitrary non-null value from the window frame, if one exists.

Syntax

ANY_VALUE(expr) [FILTER (WHERE condition) | WITHIN (WHERE condition)] OVER ([PARTITION BY expr [, ...]] [ORDER BY sort_item [, ...]] [ROWS|RANGE|GROUPS frame])

Notes

  • Returns any non-null value from the window frame
  • Useful when you need a representative value but don't care which one
  • Returns same type as input expression
  • Non-deterministic: result may vary between executions

SELECT
    -- Any non-null value in the frame (here, first in id order; v permuted so output is not v)
    f1 := ZIP(ARRAY(1, 2, 3, 4) AS id, ARRAY(30, 10, 20, 5) AS v).TRANSFORM(
        SELECT ANY_VALUE(v) OVER (ORDER BY id ASC)
    ).UNWRAP(),
    -- Any value counting only rows where v > 15 (10 and 5 excluded from the frame)
    f2 := ZIP(ARRAY(1, 2, 3, 4) AS id, ARRAY(30, 10, 20, 5) AS v).TRANSFORM(
        SELECT ANY_VALUE(v) FILTER (WHERE v > 15) OVER (ORDER BY id ASC)
    ).UNWRAP()
;
Result
