Question

我创建了表格：

CREATE TABLE SALES_ORDER2_56 (
    ORDERNO VARCHAR2 (6) CONSTRAINT SOpkey1 PRIMARY KEY CONSTRAINT SOcheck1 CHECK (ORDERNO LIKE 'O%'),
    CLIENTNO VARCHAR2 (6) CONSTRAINT SOfkey1 REFERENCES CLIENT_MASTER2_56 (CLIENTNO),
    ORDERDATE DATE CONSTRAINT SOnull1 NOT NULL,
    DELYADDR VARCHAR2 (25),
    SALESMANNO VARCHAR2 (6) CONSTRAINT SOfkey2 REFERENCES SALESMAN_MASTER2_56 (SALESMANNO),
    DELYTYPE CHAR (1) DEFAULT 'F',
    CONSTRAINT SOcheck2 CHECK (
        DELYTYPE LIKE 'F'
        OR DELYTYPE LIKE 'P'
    ),
    BILLYN CHAR (1),
    DELYDATE DATE,
    ORDERSTATUS VARCHAR2 (10),
    CHECK (
        ORDERSTATUS IN (
            'In Process',
            'Fulfilled',
            'BackOrder',
            'Cancelled'
        )
    ),
    CONSTRAINT SOcheck3 CHECK (DELYDATE > ORDERDATE)
);

但每当我尝试运行时：

INSERT INTO SALES_ORDER2_56 (ORDERNO,CLIENTNO,ORDERDATE,SALESMANNO,DELYTYPE,BILLYN,DELYDATE,ORDERSTATUS)
    VALUES('O19001','C00001','12-jun-04','S00001','F','N','20-jul-04','In Process');

它给了我： [Err] ORA-02291：违反了完整性约束（SCOTT.SOFKEY2） - 未找到父键

我尝试了很多次但是徒劳无功。非常感谢帮助。

这个回答是对问题的原始版本的回应，它已被编辑，使答案看起来无关紧要。

CHECK的{{1}}约束要求ORDERSTATUS是ORDERSTATUS，In Progress，Fulfilled或BackOrder之一，但在您的插入查询中，您使用违反约束的Cancelled。我猜你打算用In Process？

错误In Progress

表示SALESMANNO S00001在SALESMAN_MASTER2_56表中不存在

在SQL中违反约束
