@ -420,8 +420,4 @@ The number of rows considered for the `moving5` window for the `count5` column:
The following are known issues with window functions:
- Aggregates with ORDER BY specified are processed in the window: ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
This behavior differs from other databases that use the default of RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW.
In cases where the order column is unique there is no difference between RANGE / ROWS; windows with RANGE specifications are handled as ROWS.
- LEAD/LAG ignores the default value
- LAST_VALUE returns the last value of the window even when you include an ORDER BY clause
- SELECT * queries without a WHERE clause are not supported. If you want to retrieve all columns in this case, specify the column names.
