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),
(4, '4#gmail.com', 'Nick', 'Perth', 4294, 'WA', '44 happylane drive', 'Australia', 932222565621),
(5, '5#gmail.com', 'Mary', 'Perth', 6383, 'WA', '3 iverno crescent', 'Australia', 93365543321),
(6, '6#gmail.com', 'Julie', 'Perth', 9563, 'WA', '100 richmane lane', 'Australia', 9323456421),

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.

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
When I have an int column and most of the data is a number, but I have a few where there is no data and I am trying to fill it in with a null. how do you go about this? (In summary a null value in place of an int).
CREATE TABLE EmployeeSalary
(EmployeeID int,
JobTitle varchar(50),
YearsOfService int,
Salary int
);
INSERT INTO EmployeeSalary VALUES
(101, 'Manager', 20, 80000),
(102, 'Desk Clerk', 5, 30000),
(103, 'Maintanence', 10, 60000),
(104, 'Sales', 'null', 'null'),
(105, 'Operations Manager', 'null', 'null')
;
Remove quotes around null and put NULL in place of 'null'...
INSERT INTO EmployeeSalary (emp_id, emp_post, how_much_year, emp_salary) VALUES
(1, 'Computer Engineer', 20, NULL),
(2, 'Computer Scientist', NULL, 100000);
The value 'NULL', with single quotes around it, is a string literal. You want to use NULL, without quotes:
INSERT INTO EmployeeSalary (EmployeeID, JobTitle, YearsOfService, Salary)
VALUES
(101, 'Manager', 20, 80000),
(102, 'Desk Clerk', 5, 30000),
(103, 'Maintanence', 10, 60000),
(104, 'Sales', NULL, NULL),
(105, 'Operations Manager', NULL, NULL);
Note that I also added the target colums of the insert, which is considered best practice.
You are trying to save text value in YearOfService column. Whenever you wrap any value in-between apostrophe i.e. ' then it becomes a text value .
Use null instead of 'null' it should work.
Valid insert query:
INSERT INTO EmployeeSalary VALUES
(101, 'Manager', 20, 80000),
(102, 'Desk Clerk', 5, 30000),
(103, 'Maintanence', 10, 60000),
(104, 'Sales', null, null),
(105, 'Operations Manager', null, null)
;

I have to do a many to many tables between a table MEAL and a table RESTAURANT. First I created the two tables:
CREATE TABLE RESTAURANT (
ID_Restaurant VARCHAR(10) NOT NULL,
ID_Hotel VARCHAR(10) NOT NULL,
Name VARCHAR(30) NOT NULL,
Number_of_Tables INT(3) NOT NULL,
PRIMARY KEY (ID_Restaurant),
FOREIGN KEY (ID_Hotel) REFERENCES HOTEL (ID_Hotel));
CREATE TABLE MEAL(
ID_Meal VARCHAR(10) NOT NULL,
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 ;-)
I can't figure out why I'm getting this error:

Everything works up until the insert values for CurrentLoan. Here is my code:

INSERT INTO CurrentLoan VALUES (00213, 2051, '11-JUN-17', '02-OCT-17');
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.
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;

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?

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.
