Question

当我进行插入时，它会给我这个错误：

ORA-02291：违反了完整性约束（H00300581.FK_CLASSES） - 未找到父密钥

并且所有插入到注册表中的错误都会发生。我需要帮助，请尝试为我修复。

是否来自表中的外键？可能是因为我尝试了一切，但它没有用。

Answer 1

大多数语句都缺少

commas，例如：

介于'Eygpt'之间'12/3/1988' in：

 INSERT INTO G3_TRAINERS (TRAINER_ID, TRAINER_NAME, COUNTRY, DOB,
 SPECIALITY, DESCRIPTION)  VALUES (G3_TRAINERS_Seq.nextVal, 'Ahmed',
 'Eygpt' '12/3/1988', 'Body Building', 'I describe my self as an active
 guy i workout everyday and thats why i desided to train people to be
 good as me');

OR

介于'Weight Lifting Class'之间'1/12/2017'

 INSERT INTO G3_CLASSES (CLASS_NUM, TRAINER_ID, CLASS_TITLE, START_DATE, END_DATE, COST)
 VALUES (G3_CLASSES_Seq.nextVal, 10001, 'Weight Lifting Class' '1/12/2017', '1/1/2018', 1150);

您有CONSTRAINT fk_CLASSES FOREIGN KEY(CLASS_NUM) REFERENCES G3_CLASSES(CLASS_NUM)作为约束

您有G3_CLASSES_Seq个序列来填充g3_classes表的class_num列，该列对fk_CLASSES FOREIGN KEY应该很方便，但您有另一个序列G3_CLASSE_Seq以{{1}开头}。顺便说一下，它似乎应该以{{1}}

开头

即。请注意30000和30001不同。

顺便说一下，删除G3_CLASSE_Seq中G3_CLASSES_Seq之间的空格，如下所示：

作为示例，转换此

column names

到此：

create sentences

以下声明（CREATE TABLE G3_TRAINERS ( TRAINER_ID VARCHAR(6) NOT NULL, TRAINER_NAME VARCHAR(50) NOT NULL, COUNTRY VARCHAR(25) NOT NULL, DOB DATE NOT NULL, SPECIALITY VARCHAR(30) NOT NULL, DESCRIPTION VARCHAR(500) NOT NULL, PRIMARY KEY (TRAINER_ID) );）

中还有另一个问题

插入G3_REGISTRATION（REGISTRATION_ID，MEMBER_ID， AMOUNT_TO_PAY，CLASS_NUM）VALUES（G3_REGISTRATIONS_Seq.nextVal， 20003,1150，CREATE TABLE G3_TRAINERS ( TRAINER_ID VARCHAR(6) NOT NULL, TRAINER_NAME VARCHAR(50) NOT NULL, COUNTRY VARCHAR(25) NOT NULL, DOB DATE NOT NULL, SPECIALITY VARCHAR(30) NOT NULL, DESCRIPTION VARCHAR(500) NOT NULL, PRIMARY KEY (TRAINER_ID) );）;
