如何在 where 中設置條件。 續集 mysql

Question

應該獲取在 coursesOffered 數組中找到值“搜索”的所有教師。

表老師

name lastName dob coursesOffered

胡安佩雷斯 2022/10/02 ['數學'，'科學']

馬科斯·史密斯 2022/10/02 [ '歷史', '文學' ]

查詢續集

const search = 'math';

const teachers = await Teacher.findAll({
    where: should fetch all teachers where the value 'search' is found in the coursesOffered array.
})

Answer 1

你可以試試JSON_CONTAINS function。

// When you are doing string search, make sure to wrap the search term with "".
const teachers = await Teacher.findAll({
    where: Sequelize.fn('JSON_CONTAINS', Sequelize.col('coursesOffered'), `"${search}"`)
})
