how do read single column data from realm database?

[Mob Code]

One table with three column which named "Id,Name,Last Name". For get data of Name column in sq-lite we are using query like 'SELECT Name form table_name' if we using realm in "IOS" then which method we use for get only one column data. Thanks

Hi Mob Code,

not sure if you are using Swift or Objective-C but maybe you have a look at the section: "Querying with Predicates"

Swift: https://realm.io/docs/swift/latest/#querying-with-predicates

ObjC: https://realm.io/docs/objc/latest/#querying-with-predicates

Hope that helps!

Kind regards,

Sebastian

Realm reads data only when you access the property, so you don't need to explicitly list which columns you want when querying. If you loop over the results of a query and only access the Name property of the returned objects, only the data for that column will be read.
