PRODUCT() OVER ...

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

Returns the product of values in the window frame.

Syntax

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

Notes

  • SQL translation is implemented only when the current SQL backend is DuckDB
  • Requires a well-defined window (ORDER BY, and optionally PARTITION BY and frame)
  • NULL values are ignored where the underlying window aggregate skips NULLs
