Hey everyone I need some help with creating tables. I have the script below and it creates a few tables. When i try to run the script it give me this error:
psql:script.sql:10: ERROR: syntax error at or near "Group"
LINE 6: CREATE TABLE Group(
Can anyone tell me what is going on?
CREATE TABLE Group(
name varchar(40) PRIMARY KEY NOT NULL
);
CREATE TABLE Artist(
name varchar(30) PRIMARY KEY NOT NULL,
birthplace varchar(20) NOT NULL,
age int NOT NULL CHECK (age > 0),
style varchar(20) NOT NULL
);
CREATE TABLE Artwork(
title varchar(40) PRIMARY KEY NOT NULL,
artist varchar(30) NOT NULL references Artist(name),
group_name varchar(40) NOT NULL references Group(name),
year int NOT NULL CHECK (year > 0),
type varchar(30) NOT NULL,
price money NOT NULL,
);
CREATE TABLE Customer(
cust_id int PRIMARY KEY NOT NULL,
name varchar(40) NOT NULL,
address varcahr(60) NOT NULL,
amount money NOT NULL CHECK(amount > 0),
like_artist varchar(30) NOT NULL references Artist(name),
like_group varchar(40) NOT NULL references Group(name)
);
it had a lot of problems
this worked for me. In postgres, names that are not all lowercase need to be double quoted. also some of your table names are reserved words, money can't be > and int, and there was a comma out of place.
CREATE TABLE "group"( name varchar(40) PRIMARY KEY NOT NULL );
CREATE TABLE artist( name varchar(30) PRIMARY KEY NOT NULL, birthplace varchar(20) NOT NULL, age int NOT NULL CHECK (age > 0), style varchar(20) NOT NULL );
CREATE TABLE artwork( title varchar(40) PRIMARY KEY NOT NULL, artist varchar(30) NOT NULL references artist(name),
group_name varchar(40) NOT NULL references "group"(name), year int NOT NULL CHECK (year > 0), type varchar(30) NOT NULL, price money NOT NULL );
CREATE TABLE customer( cust_id int PRIMARY KEY NOT NULL, name varchar(40) NOT NULL, address varchar(60) NOT NULL,
amount money NOT NULL CHECK(amount > cast(0.0 as money)), like_artist varchar(30) NOT NULL references artist(name), like_group varchar(40) NOT NULL references "group"(name) );

This is my code:
CREATE TABLE supplier -- creating table supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
I get the the error:
Msg 2714, Level 16, State 6, Line 34
There is already an object named 'supplier' in the database.
Any help? Thanks!
Please try this code.
IF EXISTS(SELECT 1 FROM sys.tables WHERE name = 'supplier')
DROP TABLE dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
You need to check if the table exists first
IF OBJECT_ID('dbo.supplier', 'U') IS NOT NULL
DROP TABLE dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
If you are using 2016+ you can use
DROP TABLE IF EXISTS dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO

If you are doing this in one execution, you would need to include a ; at the end of each of your table creation statements.

I am completely new to writing SQL code and I am attempting to run a simple table creation, however I cannot find where the error in my programming is, and as I am completely new I am struggling with this creation.
This is a school project that I am working on, and hoping anyone can help.
The error I am receiving in 'SQLFiddle' is "Cannot add foreign key constraint" on the following code:
CREATE TABLE invoice(
invoice_id INT NOT NULL,
customer_id INT NOT NULL,
order_date DATE NULL,
spec_order_note VARCHAR(45) NULL,
PRIMARY KEY(invoice_id, customer_id),
FOREIGN KEY (customer_id)
REFERENCES customer.customer_id
ON DELETE CASCADE
ON UPDATE CASCADE
);
CREATE TABLE line_item (
invoice_id INT NOT NULL,
donut_id INT NOT NULL,
quantity INT NULL
CONSTRAINT donut_invoice
FOREIGN KEY invoice_id
REFERENCES invoice.invoice_id
ON DELETE RESTRICT
ON UPDATE RESTRICT
)
CREATE TABLE donut (
donut_id INT NOT NULL,
donut_name VARCHAR(15) NULL,
description VARCHAR(30) NULL,
unit_price INT NULL
PRIMARY KEY(donut_id),
)
CREATE TABLE customer (
customer_id INT NOT NULL,
last_name VARCHAR(15) NULL,
first_name VARCHAR(10) NULL,
street_add VARCHAR(20) NULL,
apt_num INT NULL,
city VARCHAR(20) NULL,
state VARCHAR(15) NULL,
zip_code INT NULL,
home_phone VARCHAR(10) NULL,
mobile_phone VARCHAR(10) NULL,
other_phone VARCHAR(10) NULL,
customer_notes VARCHAR(45) NULL
PRIMARY KEY(customer_id),
)
Any help is greatly appreciated.
You can only reference existing tables and columns in foreign constraints. So if you want to reference customer table in invoice's foreign key, you need to either create customer before invoice or add the foreign key constrain additionally using ALTER TABLE.
Apart of that, there's couple syntax errors in your code like missing semicolons and misplaced (missing and additional) commas.
A working code:
CREATE TABLE customer (
customer_id INT NOT NULL,
last_name VARCHAR(15) NULL,
first_name VARCHAR(10) NULL,
street_add VARCHAR(20) NULL,
apt_num INT NULL,
city VARCHAR(20) NULL,
state VARCHAR(15) NULL,
zip_code INT NULL,
home_phone VARCHAR(10) NULL,
mobile_phone VARCHAR(10) NULL,
other_phone VARCHAR(10) NULL,
customer_notes VARCHAR(45) NULL,
PRIMARY KEY(customer_id)
);
CREATE TABLE invoice(
invoice_id INT NOT NULL,
customer_id INT NOT NULL,
order_date DATE NULL,
spec_order_note VARCHAR(45) NULL,
PRIMARY KEY(invoice_id, customer_id),
FOREIGN KEY (customer_id)
REFERENCES customer (customer_id)
ON DELETE CASCADE
ON UPDATE CASCADE
);
CREATE TABLE line_item (
invoice_id INT NOT NULL,
donut_id INT NOT NULL,
quantity INT NULL,
CONSTRAINT donut_invoice
FOREIGN KEY (invoice_id)
REFERENCES invoice (invoice_id)
ON DELETE RESTRICT
ON UPDATE RESTRICT
);
CREATE TABLE donut (
donut_id INT NOT NULL,
donut_name VARCHAR(15) NULL,
description VARCHAR(30) NULL,
unit_price INT NULL,
PRIMARY KEY(donut_id)
);

CREATE TABLE detectives(
id INTEGER NOT NULL AUTO_INCREMENT,
first_name VARCHAR(50),
last_name VARCHAR(50) NOT NULL,
phone_number VARCHAR(10) NOT NULL,
certification_date DATE NOT NULL,
CONSTRAINT detectives_pk PRIMARY KEY (id
);
It says: Incorrect syntax near 'AUTO_INCREMENT'.
Any help with this?
Missing closing ) and using incorrect syntax for an IDENTITY field.
CREATE TABLE detectives(
id INT IDENTITY,
first_name VARCHAR(50),
last_name VARCHAR(50) NOT NULL,
phone_number VARCHAR(10) NOT NULL,
certification_date DATE NOT NULL,
CONSTRAINT detectives_pk PRIMARY KEY (id)
)
Change
id INTEGER NOT NULL AUTO_INCREMENT,
To
ID INT NOT NULL IDENTITY(1,1),
you've to make the column identity if you want auto increment. your code will be
CREATE TABLE detectives(
id INT NOT NULL IDENTITY (1, 1),
first_name VARCHAR(50),
last_name VARCHAR(50) NOT NULL,
phone_number VARCHAR(10) NOT NULL,
certification_date DATE NOT NULL,
CONSTRAINT detectives_pk PRIMARY KEY (id)
);
I've spent a while trying to firgure it but but I can't see anything that would be causing this error. I'm thinking maybe something to do with the "Unique" statement.

Loan references Item, but you create Loan before you create Item. Create the Item table first.
