How to output a list of all orders placed on day X as calculate the total number of repairs and the total amount spent on them - sql

can you help me to solve this:
Make a list of all orders placed on day X as
calculate the total number of repairs and the total amount spent on them

UPDATE Orders SET Date_of_deadline ='2021-10-15' WHERE ID=7;
I did this, but I don't know if it's right
I don't know how to fix it:
SELECT Date_of_deadline,Type_of_repair,Price
FROM Orders
WHERE Orders.Status_order = 'Submitted'(
SELECT SUM(Price) AS 'Sum of repairs'
FROM Orders
WHERE Orders.Status_order = 'Submitted')

I'm confused by your code, you made two separate queries right?
I think you forgot to add a count(1) on the second select as to calculate the total amount of orders and add the date as where parameter to equal it to X

-- display Total number of customers who booked a single room with sea view option

Any help would be greatly appreciated, thank you in advance!
Your FROM clause is missing the join condition for each table. In other words you are getting the cartesian product (every combination of rows) of the tables. Even distinct won't help (it will get the wrong answer). Use join conditions to link the keys of each table to each other. I'll leave this an exercise for you to try out, but this should be enough information to help you out.
I believe the solution for your problem is that you need to use DISTINCT:
SELECT COUNT(DISTINCT(Firstname))
FROM LocationOfRoom, customer, RoomType, Room
WHERE seaview='yes' AND singleRoom='yes'
I have tested it and it retrieves 9 Rooms.

error 1452 when trying to paste in values

when i try enter the last part of code i get the error message "error code : 1452 cannot add or update a child row a foreign key constraint fails"
CREATE TABLE products (
id int auto_increment primary key,
name varchar (30),
price decimal(3,2),
coffee_origin varchar (30)
);
CREATE TABLE customers (
id INT AUTO_INCREMENT PRIMARY KEY,
first_name VARCHAR(30),
last_name VARCHAR (30),
gender ENUM ('M','F'),
phone_number VARCHAR(11)
);
CREATE TABLE orders(
id INT AUTO_INCREMENT PRIMARY KEY,
product_id INT,
customer_id INT,
order_time DATETIME,
FOREIGN KEY (product_id) REFERENCES products(id),
FOREIGN KEY (customer_id) REFERENCES customers(id)
);
INSERT INTO orders (product_id,customer_id,order_time) VALUES (1,1,'2017-01-01 08-02-11');
In order to be able to insert your values into the orders table, I think you might need to add rows to your products and customers tables.
Here are possible examples of how you could add rows to your products and customers tables:
insert into products (name, price, coffee_origin) values ('Dark Blend', 4.99, 'Brazil');
insert into customers (first_name, last_name, gender, phone_number) values ('First Name', 'Last Name', 'M', '123-456-7890');
Then, you can find the id values that you might need to use for your final insert action by running the following queries:
select id from products where name = 'Dark Blend';
select id from customers where phone_number = '123-456-7890';
Finally, you can try running your insert action again, but this time using the id values from the queries above this; maybe like this, if you get back 1 for the ids of each of those queries above:
insert into orders (product_id, customer_id, order_time) values (1, 1, '2021-01-01 00:00:00');

Violation of PRIMARY KEY constraint 'PK__Transact__'. Cannot insert duplicate key in object 'dbo.Transactions_ID'. The duplicate key value is (1001)

When I am trying to insert execute the table and I am getting that error. And when I try to insert more rows into Employee_in I get an error

Violation of PRIMARY KEY constraint 'PK__Transact__'. Cannot insert duplicate key in object 'dbo.Transactions_ID'. The duplicate key value is (1001)
This means you already have a value 1001 for the PK TransactionID in your table, most likely from and earlier insert.
INSERT INTO Transactions_ID (TransactionID, EmployeeID, PostalDate, Amount)
VALUES ('1001', '1001', '2020-04-07', '20000')
Here you are trying to insert string in columns with a datatype int... this should be:
INSERT INTO Transactions_ID (TransactionID, EmployeeID, PostalDate, Amount)
VALUES (1001, 1001, '2020-04-07', '20000')
Good luck!

Draft so far:
SELECT DISTINCT Customer.Name, Customer.Address
FROM Customer, Account, Loan, Has_Account, Has_Loan
WHERE Customer.Ssn = Has_Account.Assn AND Has_Account.Assn = Has_Loan.Lssn
(SELECT Account.Balance MAX(Balance) GROUP BY(BranchID)) AND
Loan.AMOUNT(SELECT Loan.Amount MIN(Amount) GROUP BY(BranchID));
I think it is correct that we need to group our output by BranchID, and max/min is ok. Looks like the statement formalities are wrong somehow.
Any help or hint is much appreciated!
