MySQL的日期的年月间

Question

如何查询日期和月份和年份from_date和to_date之间？

我累了什么：

$posts = my_table::whereYear('from_date', '>=', $year)
    ->whereMonth('from_date', '>=', $month)
    ->whereYear('to_date', '<=', $year)
    ->whereMonth('to_date', '<=', $month)
    ->get();

查询我想执行：

SELECT * FROM my_table
WHERE (MONTH(from_date)>=2 AND (Year(from_date)>=2019)
  AND (MONTH(to_date)=<4 AND (Year(to_date)=<2019)
