a question about AR

Hi,i’m a newbie,i wanna ask a question about efficiency of AR.

When i use model()->find() to have a query,the result returns a lot of information that maybe i don’t need,for example,table information. i think it will reduce the efficiency of AR.

how can i get the result which only have the query result that i need!

Configure a cache component and schemaCachingDuration in your connection.

Thanks for your tips!
