Codeigniter this- db- get how do I return values for a specific row

Question

Say I have a database table with three columns  ID  Name  and Age  I need to find the user with a specific  unique  ID  and then return the age  Currently  I am using the following code   this- gt db- gt where  id    3     q    this- gt db- gt get  my users table      How do I go about getting the age for this user  I think I have to use   q- gt result     But not sure how to use it with one row

Incase you are dynamically getting your data e g When you need data based on the user logged in by their id use consider the following code example for a No Active Record     this- gt db- gt query  SELECT   FROM my users table WHERE id        this- gt session- gt userdata  id       return  query- gt row array      This will return a specific row based on your the set session data of user
