问题描述
我在 Sequelize 中有一个带有两个日期列的表格 - 即:
I have a table in Sequelize with two date columns - i.e. with :
var Visit = sequelize.define("Visit", {
/*...*/
scheduleEndDate: {
type: DataTypes.DATE
}
actualEndDate: {
type: DataTypes.DATE
}
/*...*/
});
我想进行一个查询,该查询返回实际结束日期在 scheduleEndDate 之前的行 - 并且无法获得正确的格式.我为 findAll
查询的 where
部分尝试的是:
I want to make a query that returns rows where actualEndDate is before scheduleEndDate - and can't get the format right. What I've tried for the where
part of my findAll
query is:
where: { actualEndDate: { lt: Visit.scheduleEndDate } }
- 由于未定义访问而引发错误(也尝试使用 this.scheduleEndDate - 也引发错误)
- throws an error because Visit not defined (have also tried with this.scheduleEndDate - also throws an error)
where: { actualEndDate: '< scheduleEndDate' }
- 将 actualEndDate 与字符串 '< 进行字符串比较.scheduleEndDate'
- does a string comparison of actualEndDate against the string '< scheduleEndDate'
我是否需要定义一个实例方法来进行日期比较/如何最好地解决?
Do I need to define an instance method to do the date comparison / how best to solve?
推荐答案
这应该可以通过
where: { actualEndDate: { $lt: sequelize.col('scheduleEndDate') } }
