Hey ,

I want to update my DB column, for this i have successfully run the following query.
and updated column "TotalMembers" by 1.

But now i want to do this using Active Record Class in CI,
Can anyone help me how i have to do this?

Code:

UPDATE
   GBSociety  
     SET TotalMembers=TotalMembers+1  // incremented by 1 or some value e,g ,10,12. etc
     WHERE SocietyID=$pSocietyID;
