How can I query data from a realm database?

You can query data from a realm database using Realm's query language. What specific data are you looking to retrieve?

I want to find all users who are over 18 years old.

You can use the following query: realm.objects('User').filtered('age > 18'). This will return all users older than 18.

Can I sort the results by name?

Yes, you can chain the sorted method to your query: realm.objects('User').filtered('age > 18').sorted('name').

What if I want to limit the number of results?

You can use the slice method to limit results, like this: realm.objects('User').filtered('age > 18').sorted('name').slice(0, 10) to get the first 10 results.
