问题 How can I get data with custom where conditions? In this question Sequelize - function on column in a where clause, I have a similar problem, but this one I believe uses MySQL built-in functions and it fetches data within a radius.

问题 I am able to create records in my MySQL DB with sequelize and NodeJS. But now I am trying to update records in my Database. I have NodeJS as backend and my DB is MySql. Sequelize is my ORM.
