Trying to perform an insert into - mysql
Been trying to perform an insert into command for a table called customers. However whenever I try to do a query I get the following error.
Error Code: 1364. Field 'customer_address' doesn't have a default value 0.000 sec
I'm not entirely sure how I would go about setting a default value. Any suggestions?
lock table customers write;
set foreign_key_checks = 0;
alter table customers modify customer_id integer auto_increment;
insert into customers (customer_first_name, customer_last_name)
values ("Nathan", "Rivera"),
("thom", "something");

Error Code: 1364. Field 'customer_address' doesn't have a default value 0.000 sec
That means that the customer_address column is set to NOT allow NULL values and that no default value has been specified. Therefore your insert statement must include the customer address field.
insert into customers (customer_first_name, customer_last_name, customer_address)
values ("Nathan", "Rivera", "1000 Fred St."),
("thom", "something", "9659 Foobar Dr.");
Now that you've added your table defs it's clear that you'll need the other fields that you've marked NOT NULL as well in the insert statement, or you'll see a similar error for each one you leave out.
You can specify a default value using the DEFAULT option in the CREATE TABLE query.

If you want 159 change your last select query to below. SELECT 'carti disponibile', '--------', '--------', Sum(carti.stoc) - (SELECT Count(*) FROM imprumuturi) FROM carti; DEMO
The reason you get garbage value in the stoc column is because of the 14th line in your above code. Its expecting a number but you are changing the datatype to string and hence the garbage values. Try changing ----- to a number like 0 for example and you should get the desired output See below on sql fiddle http://sqlfiddle.com/#!9/25e5a1/17 SELECT titlucarte, numeautor, numeeditura, stoc FROM carti JOIN autori ON ( carti.idautor = autori.idautor ) JOIN edituri ON ( carti.ideditura = edituri.ideditura ) UNION SELECT '--------------------------------------' as 'titlucarte', '--------' as 'numeautor', '--------' as 'numeeditura', /*'----' as 'stoc' */ /*code removed*/ 0 as stoc /* code added*/ UNION SELECT 'total carti' as 'titlucarte', '--------' as 'numeautor', '--------' as 'numeeditura' , Sum(stoc) as 'stoc' FROM carti UNION SELECT '--------------------------------------' as 'titlucarte', '--------' as 'numeautor', '--------' as 'numeeditura' , '----' as 'stoc' UNION SELECT 'carti disponibile' as 'titlucarte', '--------' as 'numeautor', '--------' as 'numeeditura' , Sum(carti.stoc) - (SELECT Count(*) FROM imprumuturi) as 'stoc' FROM /*imprumuturi,*/ carti;

This is my first time working with anything SQL related and have tried referring to the MySQL docs, but don't know what I'm doing wrong. The error does not appear until after the bottom 2 INSERT INTO statements are added. Any help would be greatly appreciated.
You are getting this error because you are trying to insert data set in table whose references are missing in referenced table for example in Order_Items you are trying to link custorder table with Donut_Order_ID 2 and 3 but it is empty
So first fill your custorder and then link with your table
INSERT INTO CustOrder VALUES
('1', '11-24-2017', NULL, '1'),
('2', '11-25-2017', NULL, '2');
INSERT INTO Order_Items VALUES
(2 , 4 , 3),
(3, 2, 1);
Also i see there is no reference present in CustOrder for Donut_Order_ID = 3 but in Order_Items data you have trying to link with this missing reference which will again give you error

Many-to-Many Tables SQL
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 ;-)
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.

(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.
