我这里有复杂的脚本，我需要找到所有的DAYNAME（在我的effectiveDate列FROM schedules表中）但是你可以看到我的脚本 DAYNAME（有效日期）=＆＃39;星期日＆＃39;那么这是星期天＆＃39;不管用 如果你想看到我在这里1屏幕截图的结果。 as you can see the effectiveDate 2017-01-01 is Sunday and 2017-01-15 is Sunday also. but the result only null. how to get the result. if dayname = 'Sunday' then it will result sunday same as in Saturday also.
