Sequelize: Concat fields in WHERE LIKE clause - mysql

Question

I am using the sequelize ORM for a node.js project I am working on. One query I have, I need to perform a like operation on the concatenated result of multiple columns.
For instance, something like the following:
SELECT * FROM People WHERE (CONCAT(firstname, ' ', lastname)) LIKE '%John Do%'.
I am using the following syntax and would like to know if this is possible without having to resort to using RAW queries (which is nowhere else in my solution).
var criteria = {
include: [
occupation
],
where: {
is_active: 1
},
nest: false
};
db.people.findAll(criteria, {}).then(function(people) {
success(people);
}).catch(function(err) {
error(err);
});
Any ideas?

Answer 1

You'll need something like this
var criteria = {
where: Sequelize.where(Sequelize.fn("concat", Sequelize.col("firstname"), Sequelize.col("lastname")), {
like: '%John Do%'
})
}
Note: untested

Inspired by #code-jaff but you need to concatenate a space string in between first and last names to make this work correctly. Otherwise it would only return for 'JohnDoe' and not for 'John Doe'. Here's the code.
Sequelize.where(Sequelize.fn('concat', Sequelize.col('firstName'), ' ', Sequelize.col('lastName')), {
like: '% John Doe %'
})
To provide some context for people who might not understand where this would fit into your query, this is an example of the above code in a where or statement. req.body.query being the variable search term that you're POSTing.
Users.findAll({
where: {
$or: [
Sequelize.where(Sequelize.fn('concat', Sequelize.col('firstName'), ' ', Sequelize.col('lastName')), {
like: '%' + req.body.query + '%'
}),
{ email: { $like: '%' + req.body.query + '%' } },
{ companyName: { $like: '%' + req.body.query + '%' } }
]
}
})
Update for Sequelize 4.0
String based operators ($like and $or in the above example) have been deprecated in favour of symbol based operators. It's a good thing for security
See: http://docs.sequelizejs.com/manual/tutorial/querying.html#operators
These operators would be replaced with [Sequelize.Op.like] and [Sequelize.Op.or]. There are also other ways to configure it in your sequelize options highlighted in their documentation

Answer 3

I was able to achieve this with the new sequelize version 5.21.13 based on #yjimk answer.
Users.findAll({
where: {
[sequelize.Op.or]:{
namesQuery: sequelize.where(
sequelize.fn(
"concat",
sequelize.col("firstName"),
" ",
sequelize.col("lastName")
),
{
[sequelize.Op.like]: `%${req.body.query}%`,
}
),
email: {[sequelize.Op.like]: `%${req.body.query}%`},
companyName: {[sequelize.Op.like]: `%${req.body.query}%`},
}
})

Answer 4

db.models.users.findOne({
where: {
[db.sequelize.Op.and]: [
db.sequelize.where(
db.sequelize.fn('CONCAT', db.sequelize.col('first_name'), ' ', db.sequelize.col('last_name')),
{ like: `%${name}%` },
),
{ status: 'ACTIVE' },
]
}
});
