适合我的解决方案是:-

The solution which works for me is this:-

// here startDate and endDate are Date objects
const where = {
    from: {
        $between: [startDate, endDate]
    }
};

注意:在MYSQL中，between比较运算符是inclusive，这意味着它等价于表达式(startDate <= from AND from <= endDate).

Note: In MYSQL between comparison operator is inclusive, which means it is equivalent to the expression (startDate <= from AND from <= endDate).
