问题 I'm trying to find the average of a 'ratings' column for all the data that has the same 'VenueId'. I have it working with raw code but need to adapt it in Sequelize. The working raw code is SELECT venueId, AVG(rating) AS average FROM reviews GROUP BY VenueId The code I've tried is Review.findAll({ order: [[Sequelize.fn('AVG', Sequelize.col('rating'))]] }).then(function(Venues) {}) I'm getting an error: Executing (default): SELECT id, review, rating, createdAt, updatedAt, VenueId FROM Reviews

问题 I am trying to querying a join table using sequelize: Here is the model: db.client.belongsToMany(db.user, { through: db.clientUser, onDelete: 'cascade', }); db.user.belongsToMany(db.client, { through: db.clientUser, }); and this is what I am trying to do: db.user.findAll({ where: { group_id: 1, }, include: [{ model: db.clientUser, where: { is_manager: 1, } }], raw: true, }) However I get the following error: client_user is not associated to user! Any idea what could be the cause of this issue

问题 I am hoping somebody can help me. I am using the Sequelize ORM for express.js and I have a working many-to-many relationship between 2 tables. For the sake of simplifying my query lets pretend my tables are Users, Books and UserBooks where UserBooks has UserId, BookId and an additional column (Lets say its NoOfTimesRead). What I want to do is something like: user.getBooks({ where: { "userBooks.NoOfTimesRead": 0 } }); If I type: user.getBooks(); This works and returns all books, I just haven't

问题 Assuming the most simple example: var Person = sequelize.define('Person', { name: Sequelize.STRING, }); Person.hasMany(Person, { as: 'Children', foreignKeyConstraint: true }); If we sequelize.sync this, we get a ChildrenPersons join table that has a two-column primary key, formed by PersonId and ChildrenId , but no foreign keys: CREATE TABLE `ChildrenPersons` ( `PersonId` int(11) NOT NULL DEFAULT '0', `ChildrenId` int(11) NOT NULL DEFAULT '0', `createdAt` datetime NOT NULL, `updatedAt`

问题 Let's say I have the following simple model: var Foo = sequelize.define('Foo', { bar: Sequelize.STRING, }); And the table Foos in the database has a record: id bar --- --- 1 abc In order to update this record I could do the following: Foo.findById(1).then(function(foo) { foo.bar = 'xyz'; foo.save(); }); Now I have found another way to update the record without having to find it form the database: var foo = Foo.build({ id: 1, bar: 'xyz' }); foo.isNewRecord = false; // makes save use UPDATE

问题 I have a Products table and a Categories table. A single Product can have many Categories and a single Category can have many Products, therefore I have a ProductsCategories table to handle the many-to-many join. In the example below, I'm trying to associate one of my products (that has an ID of 1) with 3 different categories (that have IDs of 1, 2, & 3). I know something is off in my code snippet below because I'm getting an ugly SQL error message indicating that I'm trying to insert an

问题 Using the following tedious code, I can successfully connect to an Azure SQL Server. const Connection = require('tedious').Connection; const connection = new Connection({ userName: '[USER]', password: '[PASSWORD]', server: '[HOSTNAME]', options: {encrypt: true} }); connection.on('connect', (err) => { if (err) { console.log('error connecting', err); } else { console.log('connection successful'); } }); However, using what should be the equivalent Sequelize code, I get a connection timeout error
