I found out the values and stored it in x and p.
Since x is the result of aggregate function it contains only one value. P contains multiple value.
Now I want to divide each value stored in p with x and insert it into the database. How do i do that?

P contains multiple value.

No it doesn't, unless there is only one row returned by the SQL "Select mcap from Nifty". Otherwise it contains one value which you overwrite.

DO NOT USE JDBC INSIDE OF JSP!
