问题 I would like to setup my prepared statements with the mssql module. I created a query file for all user related requests. const db = require('../databaseManager.js'); module.exports = { getUserByName: async username => db(async pool => await pool.request() .input('username', dataTypes.VarChar, username) .query(`SELECT * FROM person WHERE username = @username;`)) }; This approach allows me to require this query file and access the database by executing the query that is needed const
