使用Sequelize按日期查询时间戳

Question

I want to find some entries in my DB through the createdAt column, but just using the date. I am using postgres and the createdAt is a timestamptz . Here is an example of what an entry in it looks like: 2019-02-27 20:17:07.05+00

This is what the setting of my query looks like:

const dateString = momentDate.format('YYYY-MM-DD')
query.createdAt = { $iLike: `%${dateString}` }

Unfortunately this is not working and I am getting the following error:

retry-as-promised:error SequelizeDatabaseError: operator does not exist: timestamp with time zone ~~* unknown

Is the issue perhaps because I am using a string? What is the right way to query by date?

Answer 1

Using function DateDiff to get days from between createdAt and dateString . Need to cast dateString to datetime

var sequelize = require('sequelize');

var dateString = '01/03/2019';
yourModel.findAll({
    where: sequelize.literal(`DATEDIFF(day,Cast(${dateString} as datetime), createdAt) = 0`)
})
.then(results => {

})
.catch(err => {

});
