Hai friends.......
My question is I have one table in that three columns a, b and c..
a=7 and b=10 given input now c value must be store as a+b means 7+10=17.
Please can anybody tell me solution...
Tahnk you.........
Don't do it, there is no need as you can work it out whenever you need it. So do not have a column c in the database, just provide method c in the model: def c a+b end
Then you can use your_object.c just as if it were a column in the db.
