SQL错误：ORA-00903：表名无效

Question

CREATE TABLE Group
(
group_name VARCHAR2(50) NOT NULL,
date_joined DATE NOT NULL,
refersTo VARCHAR2(40),
CONSTRAINT g_group_name_pk PRIMARY KEY(group_name),
CONSTRAINT g_refersTo_fk FOREIGN KEY(refersTo) REFERENCES Artist(artistic_name));

这给出了“第1行的错误：ORA-00903：无效的表名”：

CREATE TABLE Group
             *

Answer 1

由于Group是保留字，因此必须使用"来转义它。尝试以下操作或将表重命名为其他内容：

CREATE TABLE "Group"
(
group_name VARCHAR2(50) NOT NULL,
date_joined DATE NOT NULL,
refersTo VARCHAR2(40),
CONSTRAINT g_group_name_pk PRIMARY KEY(group_name),
CONSTRAINT g_refersTo_fk FOREIGN KEY(refersTo) REFERENCES Artist(artistic_name));
