Example 1: sequelize order by
order: [["createdAt", "DESC"]]
Example 2: op in sequelize
//First method
// selecting authorityId :12 or 13
model.findAll({
where: {
[Op.or]: [
{ authorId: 12 },
{ authorId: 13 }
]
}
});
Example 3: where clause in sequelize
//Sequelize provides several operators.
const { Op } = require("sequelize");
Post.findAll({
where: {
[Op.and]: [{ a: 5 }, { b: 6 }], // (a = 5) AND (b = 6)
[Op.or]: [{ a: 5 }, { b: 6 }], // (a = 5) OR (b = 6)
someAttribute: {
// Basics
[Op.eq]: 3, // = 3
[Op.ne]: 20, // != 20
[Op.is]: null, // IS NULL
[Op.not]: true, // IS NOT TRUE
[Op.or]: [5, 6], // (someAttribute = 5) OR (someAttribute = 6)
// Using dialect specific column identifiers (PG in the following example):
[Op.col]: 'user.organization_id', // = "user"."organization_id"
// Number comparisons
[Op.gt]: 6, // > 6
[Op.gte]: 6, // >= 6
[Op.lt]: 10, // < 10
[Op.lte]: 10, // <= 10
[Op.between]: [6, 10], // BETWEEN 6 AND 10
[Op.notBetween]: [11, 15], // NOT BETWEEN 11 AND 15
// Other operators
[Op.all]: sequelize.literal('SELECT 1'), // > ALL (SELECT 1)
[Op.in]: [1, 2], // IN [1, 2]
[Op.notIn]: [1, 2], // NOT IN [1, 2]
[Op.like]: '%hat', // LIKE '%hat'
[Op.notLike]: '%hat', // NOT LIKE '%hat'
[Op.startsWith]: 'hat', // LIKE 'hat%'
[Op.endsWith]: 'hat', // LIKE '%hat'
[Op.substring]: 'hat', // LIKE '%hat%'
[Op.iLike]: '%hat', // ILIKE '%hat' (case insensitive) (PG only)
[Op.notILike]: '%hat', // NOT ILIKE '%hat' (PG only)
[Op.regexp]: '^[h|a|t]', // REGEXP/~ '^[h|a|t]' (MySQL/PG only)
[Op.notRegexp]: '^[h|a|t]', // NOT REGEXP/!~ '^[h|a|t]' (MySQL/PG only)
[Op.iRegexp]: '^[h|a|t]', // ~* '^[h|a|t]' (PG only)
[Op.notIRegexp]: '^[h|a|t]', // !~* '^[h|a|t]' (PG only)
[Op.any]: [2, 3], // ANY ARRAY[2, 3]::INTEGER (PG only)
// In Postgres, Op.like/Op.iLike/Op.notLike can be combined to Op.any:
[Op.like]: { [Op.any]: ['cat', 'hat'] } // LIKE ANY ARRAY['cat', 'hat']
// There are more postgres-only range operators, see below
}
}
});
Example 4: sequelize .all()
yourTableModel.findAll({
//optional filters
where: {},
raw: true,
})
