Apache pig 筛选两个日期之间的记录

我似乎看不到任何与MySQL“BETWEEN”对应的拉丁关键字

---

我想做的是过滤两个特定日期之间的记录。关于如何使用Pig拉丁语执行此操作的任何提示？

要执行此操作，请使用过滤器

variable = FILTER variable_holding_table_data BY (GetYear(date_column)==year) AND (GetMonth(date_column)==month) AND (GetDay(date_column)=>date_day_start AND GetDay(date_column)<=date_day_end);

e.g. query = FILTER orders BY (GetYear(date)==2013) AND (GetMonth(date)==05) AND (GetDay(date)>=01 AND GetDay(date)<=31);

---

variable=通过（GetYear（date\u column）=year）和（GetMonth（date\u column）=month）以及（GetDay（date\u column）=>date\u day\u start和GetDay（date\u column）=01和GetDay（date）过滤持有表格数据的变量，使用过滤器进行过滤

variable = FILTER variable_holding_table_data BY (GetYear(date_column)==year) AND (GetMonth(date_column)==month) AND (GetDay(date_column)=>date_day_start AND GetDay(date_column)<=date_day_end);

e.g. query = FILTER orders BY (GetYear(date)==2013) AND (GetMonth(date)==05) AND (GetDay(date)>=01 AND GetDay(date)<=31);

variable=根据（GetYear（date\u列）=year）和（GetMonth（date\u列）=month）以及（GetDay（date\u列）=>date\u day\u start和GetDay（date\u列）=01和GetDay（date）过滤保存表格数据的变量
