Generate a list of all appointments in alphabetical order by patient name and by latest date and time for each patient. The list should also include the doctor scheduled and the receptionist who made the appointment.
This is my query so far:
SELECT PatientLastName, PatientFirstName, Date_Time AS 'AppointmentTime', ReasonForAppointment,
EmployeeLastName AS 'DoctorLastName', EmployeeFirstName AS 'DoctorFirstName', D.Speciality,
EmployeeLastName AS 'ReceptionistLastName', EmployeeFirstName AS 'ReceptionistFirstName'
FROM Employee_T E JOIN Doctor_T D ON E.EmployeeID = D.Doctor_ID
JOIN Appointment_T A ON D.Doctor_ID = A.Doctor_ID JOIN Patient_T P ON A.Patient_ID = P.Patient_ID
ORDER BY Date_Time DESC;

I have looked at other answers people have posted and most of them are just saying to use group by, but when I use that it just orders the either names or number of medals together just in a different order. I'm trying to get it so it says that the total number of medals simone biles has is 7 and michael phelps is 28 just in a single table.
This is the query I have that returns the sum of the medals for each olympic games they've been in, but again if I use group by it just orders them.
select a.name, gold+silver+bronze as medalTotal from athlete a join compete c using (athlete_id) group by medalTotal;
+----------------+------------+
| name | medalTotal |
+----------------+------------+
| Simone Biles | 2 |
| Simone Biles | 5 |
| Michael Phelps | 6 |
| Michael Phelps | 8 |
+----------------+------------+
you need to do the following:
group by athlete
sum each medal type
add the sum of each medal type
You need to group by athlete, not total.
You have to use an aggregation function to combine values from all the rows in a group. Use SUM() to add them together.
select a.name, SUM(b.gold+b.silver+b.bronze) as medalTotal
from athlete a
join compete c using (athlete_id)
group by a.athlete_id;
You should apply group by using something unique like athelet id.
This get all atheletes with all medals number including with zero medals
if you want just athelet with medals only use join only.
select
a.name, sum(gold+silver+bronze) as medalTotal
from
athlete a
left join
compete c on c.athlete_id = a.athlete_id
group by
a.athlete_id
I am currently trying to populate my tables with data via a SQL script and have been having issues getting my FKs cooperate while populating my book table. I've read the other threads on the issue and have tried ON DELETE CASCADE and the other suggestions of populating the FKs first didn't work for me either. I also saw you can override the FK check however that seems counterproductive to making a working database.
I've attached my scripts and create.sql runs fine but insert.sql as I said gets stuck on the last command.
Thanks for your time!

In your case, this error/failure means that the foreign key constraint is working correctly. The book insert is failing because you're trying to insert a book with a publisher that doesn't exist. Two of them, in fact:
('000003','The Great Gatsby', 'Charles Scribners Sons', '03')
You don't have "Charles Scribners Sons" publisher, only "Charles Scribner".
('000002','A Brief History of Time', '04', 'Puffin Books'),
You don't have Puffin Books publisher, only Pigeon Books.
Also, your book records are wrong, the last two of them. They've got Publisher name, then Dept ID...
In short, this is precisely the case when precisely this error should occur, because your data is malformed.
Create.sql and insert.sql both having data size and ordering issue.
I just corrected your query and now it will work fine for you.

Name VARCHAR(30) NOT NULL,
Preparation_Time VARCHAR(20),
Cooking_Time VARCHAR(20),
PRIMARY KEY (ID_Meal));
Then I created the 'joint' tables:
CREATE TABLE MEAL_SERVED(
ID_Meal VARCHAR(10) NOT NULL,
ID_Restaurant VARCHAR(10) NOT NULL,
Price INT(5) NOT NULL,
PRIMARY KEY (ID_Meal, ID_Restaurant, Price),
FOREIGN KEY(ID_Meal) REFERENCES MEAL(ID_Meal),
FOREIGN KEY(ID_Restaurant) REFERENCES RESTAURANT (ID_Restaurant));
I entered some data in the first two tables:
INSERT INTO RESTAURANT(ID_Restaurant, ID_Hotel, Name, Number_of_Tables)
VALUES ('REST1', 'H1', 'Benares Indisk Restaurant', 26);
('REST2', 'H2', 'La Gaichel', 35),
('REST3', 'H3', 'Tapas Restaurant', 17),
('REST4', 'H4', 'Faubourg 101', 19),
('REST5', 'H5', 'Pizzeria Roma', 38);
INSERT INTO MEAL(ID_Meal, Name, Preparation_Time, Cooking_Time)
VALUES ('MEAL1', 'Croque-Monsieur', '5 min', '4 min'),
('MEAL2', 'Salad', '6 min', NULL),
('MEAL3', 'Hot Dog', '3 min', '2min'),
('MEAL4', 'Panini', '6 min', '5 min'),
('MEAL5', 'Coca-Cola', NULL, NULL);
Until, now there is no problem, but when I tried to enter data in the third tables with:
INSERT INTO MEAL_SERVED(ID_Meal, ID_Restaurant, Price)
VALUES ('MEAL1', 'REST1', 50),
('MEAL4', 'REST1', 50),
('MEAL5', 'REST1', 35),
('MEAL1', 'REST2', 3.5),
('MEAL2', 'REST2', 3.5),
('MEAL4', 'REST2', 5);
for instance, then I have an error message:
FOREIGN KEY constraint failed: INSERT INTO MEAL_SERVED(ID_Meal, ID_Restaurant, Price)
I don't understand why I have this message and how to correct it. Thanks in advance.
As Shadow said in the comment section.
First, fix your typo in one of your SQL statements:
INSERT INTO RESTAURANT(ID_Restaurant, ID_Hotel, Name, Number_of_Tables)
VALUES ('REST1', 'H1', 'Benares Indisk Restaurant', 26);
('REST2', 'H2', 'La Gaichel', 35),
('REST3', 'H3', 'Tapas Restaurant', 17),
('REST4', 'H4', 'Faubourg 101', 19),
('REST5', 'H5', 'Pizzeria Roma', 38);
should be:
INSERT INTO RESTAURANT(ID_Restaurant, ID_Hotel, Name, Number_of_Tables)
VALUES ('REST1', 'H1', 'Benares Indisk Restaurant', 26),
('REST2', 'H2', 'La Gaichel', 35),
('REST3', 'H3', 'Tapas Restaurant', 17),
('REST4', 'H4', 'Faubourg 101', 19),
('REST5', 'H5', 'Pizzeria Roma', 38);
Second:
Do yourself a favor and use integers for primary keys and with the auto_increment option, you can just ignore the id.
CREATE TABLE RESTAURANT (
`id` INT NOT NULL AUTO_INCREMENT,
`hotel` INT NOT NULL,
`name` VARCHAR(30) NOT NULL,
`numberOfTables` INT NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (hotel) REFERENCES HOTEL (`id`));
CREATE TABLE MEAL(
`id` INT NOT NULL AUTO_INCREMENT,
`name` VARCHAR(30) NOT NULL,
`preparationTime` VARCHAR(20),
`cookingTime` VARCHAR(20),
PRIMARY KEY (`id`));
CREATE TABLE MEAL_SERVED(
`id` INT NOT NULL AUTO_INCREMENT,
`meal` INT NOT NULL,
`restaurant` INT NOT NULL,
Price FLOAT NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY(meal) REFERENCES MEAL(`id`),
FOREIGN KEY(restaurant) REFERENCES RESTAURANT (`id`));
Data:
INSERT INTO RESTAURANT(`hotel`, `name`, `numberOfTables`)
VALUES ('1', 'Benares Indisk Restaurant', 26),
(2, 'La Gaichel', 35),
(3, 'Tapas Restaurant', 17),
(4, 'Faubourg 101', 19),
(5, 'Pizzeria Roma', 38);
INSERT INTO MEAL(`name`, `preparationTime`, `cookingTime`)
VALUES ('Croque-Monsieur', '5 min', '4 min'),
('Salad', '6 min', NULL),
('Hot Dog', '3 min', '2min'),
('Panini', '6 min', '5 min'),
('Coca-Cola', NULL, NULL);
INSERT INTO MEAL_SERVED(`meal`, `restaurant`, `price`)
VALUES (1, 1, 50),
(4, 1, 50),
(5, 1, 35),
(1, 2, 3.5),
(2, 2, 3.5),
(4, 2, 5);
Third:
INT(3) has no effects. The space for the INT will be allocated anyway.
You can use TINYINT or SMALLINT instad, maybe. Look here: https://dev.mysql.com/doc/refman/5.7/en/integer-types.html
Fourth:
Use camel-case or snake-case but not both please ;-)
So, this is my code. When I attempt to compile it in the school provided engine, I've gotten a couple errors, and they do change each time I run it, but the one I currently have is this:
ERROR 1064 (42000) at line 123: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the
right syntax to use near '9:30, 'L210', 103, 15), (86, 25, 2,
6/10/2007 9:30, 'L210', 107, 15), (89, 25, 5' at line 2
I've already tried to take out the spaces, but it makes no difference. Would this have anything to do with the order in which I take information? Or is it something else?
I'm also not sure that the tables are dropping at step one.

The issue identified by the error message is the datetime literal, here:
INSERT INTO Sections VALUES
(81, 20, 2, 7/24/2007 9:30, 'L210', 103, 15)
^^^^^^^^^^^^^^
To get a value assigned to a datetime column, you could do this:
(81, 20, 2, '2007-07-24 09:30', 'L210', 103, 15)
^^^^^^^^^^^^^^^^^^
Datetime literals should be enclosed in single quotes, and represented in a format like 'YYYY-MM-DD' or 'YYYY-MM-DD HH:MI:SS'.
(It is also possible to pass numeric decimal values in. But no one really does that. Just use a string literal in the correct format. I believe newer versions of MySQL are more lenient than earlier versions, regarding the strictness of two characters for month, and two characters for day, and using a delimiter other than the dash. I think its also possible to omit the delimiter for a datetime
I think MySQL would also accept something like this:
'20070724093000'
But again, no one really does that. Just supply the values as strings in the standard 'YYYY-MM-DD HH:MI:SS' format.
i keep getting the error 1136 in mysql, i need help, what's wrong with this code?
