嘿大家我需要帮助创建表格。我有下面的脚本,它创建了几个表。当我尝试运行脚本时,它会给我这个错误:
psql:script.sql:10: ERROR: syntax error at or near "Group"
LINE 6: CREATE TABLE Group(
有谁能告诉我发生了什么事?
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)
);

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,
