The answer is pretty self explanatory. You have foreign keys in the table, CurrentLoan. Looking at your insert statement, you're trying to add loans for members that you have not created and books you have not created.

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

Syntax Problems? Insert Into

I'm creating an online store/database in MySQL, and I'm fairly new to the system.
Please tell me what is wrong with this statement:
CREATE TABLE IF NOT EXISTS Customers (
ID INT(15) NOT NULL AUTO_INCREMENT, -- Connects to table 'Orders' andOrderUserID
Email VARCHAR(100) NOT NULL,
PersonName VARCHAR(100) NOT NULL,
City VARCHAR(90) NOT NULL,
Zip INT(10),
CustomerState VARCHAR(50),
Address VARCHAR(200) NOT NULL,
Country VARCHAR(20),
Phone INT(50),
PRIMARY KEY (ID)
);
INSERT INTO Customers (ID, Email, PersonName, City, Zip, CustomerState, Address, Country, Phone) VALUES
(1, '1#gmail.com', 'Fred', 'Brisbane', 6543, 'QLD', '20 Not telling avenue', 'Australia', 932363626),
(2, '2#gmail.com', 'Mark', 'Perth', 3212, 'WA', ' 122 cralic road', 'Australia', 93223463221),
(3, '3#gmail.com', 'Leo', 'Melbourne', 2342, 'VIC', '90 normanly drive', 'Australia', 932645321),

(10, '10#gmail.com', 'Paul', 'Sydney', 7853, 'VIC', '78 yives road', 'Australia', 932223463621),

1.) Always post which error you get when asking for help
2.) You left a comma , at the last line
3.) int(50) does not do what you think it does. It doesn't mean a number that has 50 digits. int means data type, and it will use 4 bytes. 50, in your case, means display length. Not storage length. int is 4 bytes. It can display up to 11 digits only (with minus sign included). Therefore, your int(50) doesn't make it 50 digits long, it will hold at maximum (2^32 - 1) = 4294967295.
Make your Phone a varchar

Update Last line with below line:
(10, '10#gmail.com', 'Paul', 'Sydney', 7853, 'VIC', '78 yives road', 'Australia', 932223463621);
add semicolon

Solution:
The problem is, you mentioned Phone field as integer and given values like 93223463221.
The integer value is greater than 2147483647, hence the error.
To solve,
alter table Customers modify column Phone varchar(50);
Use the above query to modify the Phone(Integer) filed as varchar field.
Then try to insert the values.

SQL Code not running: Drop Tables and Organization issue maybe?

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.

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.

Is what I am trying to do even possible?

I've attempted to create a query that will work for your data, but this is assuming you only have one guardian for each player (Which you said in your comment that this is not possible). Here is the SQLFiddle if you want to play around with it a bit more.
SELECT p.name, pg.name AS `GuardianName`, pgpn.`number` AS `GuardianNumber`
FROM `Player` play
LEFT JOIN `Person` p ON play.playerID = p.personID
LEFT JOIN `PlayerGuardian` g ON play.playerID = g.playerID
LEFT JOIN `Person` pg ON g.guardianID = pg.personID
LEFT JOIN `PersonPhoneNumber` pgppn ON pg.personID = pgppn.personID
LEFT JOIN `PhoneNumber` pgpn ON pgpn.phoneNumberID = pgppn.phoneNumberID
The problem you're having is, how do you display multiple guardians for each player? Do you want players to show up multiple times for each guardian that player has? Then you have to worry about grouping coding level, and this can be a big hassle.
My recommendation: Use an ORM similar to CakePHP that will do the heavy lifting for you. You set up the relationships between the tables, and it will do the magic of linking them up for you, in multiple efficient queries.

Mysql Error 1136 means Column count doesn't match value count.
You seem to be inserting multiple rows with a single insert statement.
Each row of data should be in its own set of parenthesis. And each set of parenthesis should be separated by a comma. Something like this:
INSERT INTO artist

VALUES
('1', 'JM', 'John', 'Mcfierceson', '1978-05-20', '$100000', '2017-05-08', 'Cries by the Ocean'),
('2', 'Ray', 'Ray', 'Grueson', '1990-07-10', '$500000', '2017-09-12', 'Jumping Jacks'),
('3', 'Shiin', 'Charlie', 'Shiin', '1989-02-12', '$700000', '2020-12-17', 'I can feel my head'),

You are trying to plug more data than you have fields for. Try this:

FOREIGN KEY (Artistname)

INSERT INTO Track VALUES ( 'Cries by the Ocean', 'JM', 'Rock', '4'),
('Jumping Jacks', 'Ray', 'Rock', '5');
