 `FILL` clause is used to specify how to fill when there is data missing in any window, including:
 
 1. NONE: No fill (the default fill mode)
-2. VALUE: Fill with a fixed value, which should be specified together, for example `FILL(VALUE, 1.23)` Note: The value filled depends on the data type. For example, if you run FILL(VALUE 1.23) on an integer column, the value 1 is filled. If multi columns in select list need to be filled, multi values are needed in fill clause, `SELECT _wstart, min(c1), max(c1) FROM ... FILL(VALUE, 0, 0)`.

For example, if you run FILL(VALUE 1.23) on an integer column, the value 1 is filled.  If multiple columns in select list need to be filled, then in the fill clause there must be a fill value for each of these columns, for example, `SELECT _wstart, min(c1), max(c1) FROM ... FILL(VALUE, 0, 0)`.
 3. PREV: Fill with the previous non-NULL value, `FILL(PREV)`
 4. NULL: Fill with NULL, `FILL(NULL)`
 5. LINEAR: Fill with the closest non-NULL value, `FILL(LINEAR)`
