I want to query something as SQL's like query:
like
m.tuteehub.com/tag/select">select * from users where name like '%m%'
How to do the same in MongoDB? I can't find a operator for like in the Documentations.
That would have to be:
db.users.find({"name": /.*m.*/})
or, similar:
db.users.find({"name": /m/})
You're looking for something that contains "m" somewhere (SQL's '%' operator is equivalent to Regexp's '.*'), not something that has "m" anchored to the beginning of the string.
%
.*
db.users.insert({name: 'paulo'}) db.users.insert({name: 'patric'}) db.users.insert({name: 'pedro'}) db.users.find({name: /a/}) //like '%a%'
out: paulo, patric
db.users.find({name: /^pa/}) //like 'pa%'
db.users.find({name: /ro$/}) //like '%ro'
out: pedro
In PHP, you could use following code:
$collection->find(array('name'=> array('$regex' => 'm'));
