语句指定某一窗口区间数据缺失的情况下的填充模式。填充模式包括以下几种： + 1. 不进行填充：NONE（默认填充模式）。 + 2. VALUE 填充：固定值填充，此时需要指定填充的数值。例如：FILL(VALUE, 1.23)。这里需要注意，最终填充的值受由相应列的类型决定，如FILL(VALUE, 1.23)，相应列为INT类型，则填充值为1。 + 3. PREV 填充：使用前一个非 NULL 值填充数据。例如：FILL(PREV)。 + 4. NULL 填充：使用 NULL 填充数据。例如：FILL(NULL)。 + 5. LINEAR 填充：根据前后距离最近的非 NULL 值做线性插值填充。例如：FILL(LINEAR)。 + 6.
