oracle – 不能在CREATE TABLE中使用内联约束

我在Oracle中有以下作为CREATE TABLE：

CREATE TABLE cs2_users (
    empnum     varchar2(12) PRIMARY KEY,toolsId    varchar2(20) 
        CONSTRAINT nn_cs2_users_toolsId NOT NULL
        CONSTRAINT fk_cs2_users_users FOREIGN KEY REFERENCES users.userid,admin      number(1,0) DEFAULT 0
        CONSTRAINT nn_cs2_users_admin NOT NULL
        CONSTRAINT ck_cs2_users_admin (admin IN (0,1)),givenname  varchar2(30) NOT NULL,middlename varchar2(30),sn         varchar2(30) NOT NULL,mail       varchar2(50) NOT NULL
);

可是它失败并呈现此错误：

ERROR at line 5:
ORA-02253: constraint specification not allowed here`

当我行使SQL * Plus毗连时,这是版本信息：

SQL*Plus: Release 11.2.0.3.0 Production on Tue Dec 18 16:38:27 2012

救命？

办理要领

SQL> create table users( userid varchar2(20) primary key );

Table created.


SQL> CREATE TABLE cs2_users (
  2      empnum     varchar2(12) PRIMARY KEY,3      toolsId    varchar2(20) constraint nn_cs2_users_toolsId NOT NULL,4          CONSTRAINT fk_cs2_users_users FOREIGN KEY(toolsId) REFERENCES users(userid),5      admin      number(1,0) DEFAULT 0 constraint nn_cs2_users_admin NOT NULL,6          CONSTRAINT ck_cs2_users_admin CHECK(admin IN (0,7      givenname  varchar2(30) NOT NULL,8      middlename varchar2(30),9      sn         varchar2(30) NOT NULL,10      mail       varchar2(50) NOT NULL
 11  );

Table created.

固然看起来很稀疏,toolsId引用了用户的userId列.您好像更但愿toolsId列从器材表中引用toolsId列,可能假如要从用户引用userId列,则但愿将列定名为userId.但其后我会问为什么你有一个单独的cs2_users列而不是简朴地将这些信息放在users表中.
