Xcode Oracle SQL开发人员：错误未知命令（检查）

谁能告诉我为什么我的校验码给我一个错误 错误报告： 未知命令

下面是我的表格代码

PROMPT 'Creating Table property'
CREATE TABLE tp_property
(
    propertyid      NUMBER(20)   NOT NULL,
    landlordroleid      NUMBER(20)   NOT NULL,

    REFERENCES  tp_landlordrole(landlordroleid);

CONSTRAINT tp_property_CK CHECK (state IN ('NY', 'NJ', 'PA' ) ;

欢迎提出任何建议，谢谢

你有4个选择，我能想到，让我们看看

为了使外键约束不会失败，我正在创建一个虚拟的LandorRole表：

SQL> create table tp_landlordrole (landlordroleid number primary key);

Table created.

选项1：内联约束 选项2：线外约束 选项3：单独的ALTERTABLE语句 选项4：单个ALTERTABLE语句 您的失败尝试介于选项3和选项4之间，即您忘记了alter table tp_属性add，或者忘记将constraint子句包含在前面的alter table语句中

在某些情况下，您可以将上述选项组合在一起，但我建议您选择一个，以使其保持一致。内联约束有一个缺点-它们不能包含多个列。例如，不能创建内联复合主键约束

出于频繁删除/创建的目的，我认为第三个选项是最灵活的——首先创建没有约束的表，然后逐个添加所有需要的约束

最后，如果可以的话，我想提出一些反对意见/建议

不需要为构成主键的列指定NOTNULL，因为主键无论如何都不能为NULL。 重新思考列数据类型；你为什么用那么多的咒语？除非它们真的有意义，否则应该避免使用它们——例如，对于STATE列，如果它总是2个字符长。 为什么对床数/房间数/浴室数使用CHAR数据类型？我希望它们是数字，而不是字符串。

您的检查约束命令缺少ALTER TABLE ADD
