I am creating a project on Library Management System.

I want to count the no of books currently available in currently in the library.
The no. of books vary according to its issue and return.
Kindly provide me the STORED PROCEDURE and the C# code to call the sp in the windows application.
My DB details:

1. Table library contains details regarding books with columns as:
book_name, book_author, book_id, book_price, book_quantity, avail_book_qty.

2. Table book_issue contains
book_id, stu_id, issue_date, return_date

The varying no. of books must get stored in avail_book_qty.

I recommend you rethink your strategy; you probably shouldn't be storing the counts anywhere at all.

No. It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.

What you seek is no quick help... instead you are asking us to write and give the code to you. Not at all encouraged/supported.

Try out, and post specific issue if you face any.
