How to sum all the columns of a table
I have a small problem with an mysql query..
I would like to ask , how can i sum all the values that i have in my table by date range.
To summarise my question , i want to create 2 text fields where i will enter 2 dates, and after hitting submit , to show me the sum of all the fields of my table.
My table has only numeric values in all columns , and a date field.
Any help would be very appreciated.
Thank you :)
