创建表时出现postgresql语法错误

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,它给我这个错误：

psql:script.sql:10: ERROR:  Syntax error at or near "Group"
LINE 6: CREATE TABLE Group(

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)
);

解决方法

它有很多问题
这对我有用.在postgres中,不是全部小写的名称需要加双引号.还有一些你的表名是保留字,金钱不能>和int,并且有一个逗号不合适.

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) );
