I have 2 tables, one is having columns like(phy_id, Name, Location) and second table is like (phy_id, product_name, Months number).
In the second table under Months no. there are columns from 1 to 12 having different values of sales and there are some null values for sales.
Now I have to find out the name of the person which is having max sales during 12 months?
Please assist here, thanks in advance.
