The actual problem statement looks like :
• Product(prod_id, prod_name, qty_on_hand)
• Order(cust_id, prod_id, order_date, qty_ordered)
• Customer(cust_id, cust_name, phone, address)
"Write a stored procedure to take the cust_id, prod_id and qty_ordered as
input. Procedure should check if the order for a particular customer can be
fulfilled and if yes then insert the new order and update the product
quantity on hand. Display appropriate message if the order cannot be
fulfilled.
Output parameter must have updated value of the qty_on_hand"
I am new to plsql so ignore silly mistakes. I tried to code something like this :
delimiter $$
-- creating procedure
CREATE PROCEDURE order_request( cust_id int, prod_id int, qty_ordered int)
BEGIN
IF( customer.cust_id != cust_id AND product.prod_id != prod_id AND qty_ordered > product.qty_on_hand) THEN
SELECT 'invalid details' ;
ELSE INSERT INTO `orders` (`cust_id`, `prod_id`, `order_date`, `qty_ordered`) VALUES (cust_id, prod_id, current_date(), qty_ordered) ;
END IF ;
END $$
CALL order_request(3,3,2)$$
which showing me error : unknown table customer in field list
I have solved the question. Here is the solution:

INSERT INTO attendance_date

('2nd Jan');
now,
select * from attendance_today;
giving duplicates after every insertion, is there any way to avoid such duplicates inside trigger?
I'm not looking for
select distinct * from attendance_today;
after the trigger gets activated.
This will prevent duplicate values from being inserted
insert into attendance_today(s_id, s_roll_no, s_name, s_gender, class, date_today)
select *
from student cross join attendance_date ad
WHERE NOT EXISTS (
SELECT null FROM attendance_today at
WHERE ad.s_id = at.s_id and ad.date_today = at.date_today
)
order by date_today, s_id;
Try this:
begin
insert into attendance_today(s_id, s_roll_no, s_name, s_gender, class, date_today)
select * from student cross join attendance_date group by s_id order by date_today, s_id;

Am trying to insert data into 2 tables but only 1 table gets the data but the other one doesn't. I don't get any error messages but only the login table gets populated but the user doesn't.
Here is my code
CREATE DEFINER=`root`#`localhost` PROCEDURE `new_user`(
_email varchar(50),
_password varchar(255),
_name varchar(35),
_surname varchar(35)
)
BEGIN
start transaction;
insert into logins_copy (
email,
password,
created_at,
updated_at
)
values
(
_email,
_password,
current_timestamp(),
current_timestamp()
);
SELECT #user_id := id from logins_copy where email = _email;
insert into users (
user_id,
name,
surname,
updated_at
)
values
(
#user_id,
_name,
_surname,
current_timestamp()
);
commit;
END
and to test this I called the procedure:
call `new_user`("test#hotmail.com", "test123", "Adam", "James");

I'm not sure what's wrong with it. MySQL tells me all sorts of things are incorrect, it just doesn't want to be created. Also, the parameters are identical types and lengths to their respective tables.
It is your first ";" that breaks procedure definition and mysql thinks you are done and treats whatever goes after ";" as another query.
You have to use delimiter for stored procedures.
