Sequelize OR condition object

Solution 1:

Seems there is another format now

where: {
    LastName: "Doe",
    $or: [
        {
            FirstName: 
            {
                $eq: "John"
            }
        }, 
        {
            FirstName: 
            {
                $eq: "Jane"
            }
        }, 
        {
            Age: 
            {
                $gt: 18
            }
        }
    ]
}

Will generate

WHERE LastName='Doe' AND (FirstName = 'John' OR FirstName = 'Jane' OR Age > 18)

See the doc: http://docs.sequelizejs.com/en/latest/docs/querying/#where

Solution 2:

String based operators will be deprecated in the future (You've probably seen the warning in console).

Getting this to work with symbolic operators was quite confusing for me, and I've updated the docs with two examples.

Post.findAll({
  where: {
    [Op.or]: [{authorId: 12}, {authorId: 13}]
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

Post.findAll({
  where: {
    authorId: {
      [Op.or]: [12, 13]
    }
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

Solution 3:

Use Sequelize.or:

var condition = {
  where: Sequelize.and(
    { name: 'a project' },
    Sequelize.or(
      { id: [1,2,3] },
      { id: { lt: 10 } }
    )
  )
};

Reference (search for Sequelize.or)

Edit: Also, this has been modified and for the latest method see Morio's answer,

Solution 4:

In Sequelize version 5 you might also can use this way (full use Operator Sequelize) :

var condition = 
{ 
  [Op.or]: [ 
   { 
     LastName: {
      [Op.eq]: "Doe"
      },
    },
   { 
     FirstName: {
      [Op.or]: ["John", "Jane"]
      }
   },
   {
      Age:{
        [Op.gt]: 18
      }
    }
 ]
}

And then, you must include this :

const Op = require('Sequelize').Op

and pass it in :

Student.findAll(condition)
.success(function(students){ 
//
})

It could beautifully generate SQL like this :

"SELECT * FROM Student WHERE LastName='Doe' OR FirstName in ("John","Jane") OR Age>18"

Solution 5:

For Sequelize 4

Query

SELECT * FROM Student WHERE LastName='Doe' 
AND (FirstName = "John" or FirstName = "Jane") AND Age BETWEEN 18 AND 24

Syntax with Operators

const Op = require('Sequelize').Op;

var r = await to (Student.findAll(
{
  where: {
    LastName: "Doe",
    FirstName: {
      [Op.or]: ["John", "Jane"]
    },
    Age: {
      // [Op.gt]: 18
      [Op.between]: [18, 24]
    }
  }
}
));

Notes

Avoid alias operators $ (e.g $and, $or ...) as these will be deprecated
Unless you have {freezeTableName: true} set in the table model then Sequelize will query against the plural form of its name ( Student -> Students )
