Even if you want to filter by a date, you must place the expression between single quotation marks. The following formats are valid: YYYY-MM-DD HH:MM:SS and YYYY/MM/DD HH:MM:SS as well as YYYY.MM.DD HH:MM:SS
即使您想筛选某个日期，也必须将表达式设置在单引号内。可使用下列格式：JJJJ-MM-TT HH:MM:SS 和 JJJJ/MM/TT HH:MM:SS 以及 JJJJ.MM.TT HH:MM:SS
