Here is sample of my sql table:
In above table:
1: id_problem is for user to enter an amount.
2: id_patient is unique ID
3: opening_date is about when user entered the amount.
4: rialamount is currency
How to add/sum total rialamount column and search it based on opening_date ??
For example: User will be able to enter a date until another date to see what's the total amount..
How cal I make it by using my sql table?
Thanks in advance
