ORA-02291：完整性约束（H00300581.FK_CLASSES）违反 - 父键没有找到

当我做插入给我这个错误：ORA-02291：完整性约束（H00300581.FK_CLASSES）违反 - 父键没有找到

ORA-02291: integrity constraint (H00300581.FK_CLASSES) violated - parent key not found

这种错误发生的所有镶入登记表。我需要帮助，请尝试为我解决。

它来自表中的外键吗？这可能是因为我尝试了一切，但它没有奏效。

您的脚本有太多错误。有几个地方丢失了逗号。您在插入语句中使用的序列名称中存在拼写错误。首先解决这些问题。 –

@Kaushik Nayak我修复了一些小问题，我如何添加代码？ –

@Kaushik Nayak我编辑它看看它 –

commas缺少的大多数语句，如：

between 'Eygpt' & '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');

between 'Weight Lifting Class' & '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);

你有CONSTRAINT fk_CLASSES FOREIGN KEY(CLASS_NUM) REFERENCES G3_CLASSES(CLASS_NUM)为约束

你G3_CLASSES_Seq序列填充g3_classes表的class_num列，应该是方便，fk_CLASSES FOREIGN KEY，但你有另一个序列G3_CLASSE_Seq开始30000。顺便说一句，现在看来，这应该与30001

i.e. Pay attention that G3_CLASSE_Seq and G3_CLASSES_Seq are different.

的方式启动，删除空格在column names之间create sentences类似以下内容：

为例，其转换

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) 

);

对此：

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) 
);

An d在以下语句中存在另一个问题（300010）

INSERT INTO G3_REGISTRATION (REGISTRATION_ID, MEMBER_ID, AMOUNT_TO_PAY, CLASS_NUM) VALUES (G3_REGISTRATIONS_Seq.nextVal, 20003, 1150, 300010);

非常感谢，解决了我的其他问题之一，但我发布了主要问题 –

@abdulrahmanarab请看我最后编辑的外键和序列。 –

@abdulrahmanarab我认为，问题不是使用'G3_CLASSE_Seq'（你应该使用这个，从30001开始）。您正在使用'G3_CLASSES_Seq'。 –
