这个脚本我做错了什么

Question

当我运行它时，我的代码有什么错误我有这个错误

ORA-00911: caractère non valide


Create table contient(
Num_Spect varchar(30) not null,
Code_Module varchar(30) not null,
constraints pk_contient primary key (Num_Spect,Code_Module),
constraints fk_spect _t_contient FOREIGN key (Num_Spect) REFERENCES specialite(Num_Spect),
constraints fk_module _t_contient FOREIGN key (Code_Module) REFERENCES module(Code_Module));

Answer 1

单词constraints无效 - 应为constraint：

Create table contient
  (Num_Spect       varchar(30) not null,
   Code_Module     varchar(30) not null,
   constraint pk_contient
     primary key (Num_Spect, Code_Module),
   constraint fk_spect_t_contient
     FOREIGN key (Num_Spect) REFERENCES specialite(Num_Spect),
   constraint fk_module_t_contient
     FOREIGN key (Code_Module) REFERENCES module(Code_Module));

祝你好运。

Answer 2

从脚本中删除autoincrement并尝试。

_t_contient
