SQL错误：ORA-00907：缺少右括号00907. 00000 - ＆＃34;缺少右括号＆＃34;

Question

在使用sqldeveloper

创建这些表时，我得到错误缺少右括号

CREATE TABLE users (
  USER_ID NUMBER(10,0) UNSIGNED NOT NULL,
  USERNAME VARCHAR2(45) NOT NULL,
  PASSWORD VARCHAR2(45) NOT NULL,
  ENABLED NUMBER(3,0) NOT NULL,
  PRIMARY KEY (USER_ID)
);
CREATE TABLE user_roles (
  USER_ROLE_ID NUMBER(10,0) UNSIGNED NOT NULL,
  USER_ID NUMBER(10,0) UNSIGNED NOT NULL,
  AUTHORITY VARCHAR2(45) NOT NULL,
  PRIMARY KEY (USER_ROLE_ID),
  KEY FK_user_roles (USER_ID),
  CONSTRAINT FK_user_roles FOREIGN KEY (USER_ID) 
  REFERENCES users (USER_ID)
);

更新...我修改了数据类型但错误相同

sudo /opt/codedeploy-agent/bin/install auto

Answer 1

Oracle不支持
• UNSIGNED 。

• KEY FK_user_roles (USER_ID)

  在语法上不正确。

创建表格如下所示：

SQL> CREATE TABLE users (
  2    USER_ID NUMBER(10,0)  NOT NULL,
  3    USERNAME VARCHAR2(45) NOT NULL,
  4    PASSWORD VARCHAR2(45) NOT NULL,
  5    ENABLED NUMBER(3,0) NOT NULL,
  6    PRIMARY KEY (USER_ID)
  7  );

Table created.

SQL> CREATE TABLE user_roles (
  2    USER_ROLE_ID NUMBER(10,0)  NOT NULL,
  3    USER_ID NUMBER(10,0)  NOT NULL,
  4    AUTHORITY VARCHAR2(45) NOT NULL,
  5    PRIMARY KEY (USER_ROLE_ID),
  6    CONSTRAINT FK_user_roles FOREIGN KEY (USER_ID)
  7    REFERENCES users (USER_ID)
  8  );

Table created.

 CREATE TABLE users (
  USER_ID INT/*(10) UNSIGNED*/ NOT NULL,
  USERNAME VARCHAR(45) NOT NULL,
  PASSWORD VARCHAR(45) NOT NULL,
  ENABLED tinyint/*(1)*/ NOT NULL,
  PRIMARY KEY (USER_ID)
);

CREATE TABLE user_roles (
  USER_ROLE_ID INT/*(10) UNSIGNED*/ NOT NULL,
  USER_ID INT/*(10) UNSIGNED*/ NOT NULL,
  AUTHORITY VARCHAR(45) NOT NULL,
  PRIMARY KEY (USER_ROLE_ID),
  /*KEY FK_user_roles (USER_ID),*/
  CONSTRAINT FK_user_roles FOREIGN KEY (USER_ID) 
  REFERENCES users (USER_ID)
);
