Sql 类表继承模型的INSERT语句
我有两个表，定义如下：Sql 类表继承模型的INSERT语句,sql,postgresql,inheritance,foreign-keys,insert-into,Sql,Postgresql,Inheritance,Foreign Keys,Insert Into,我有两个表，定义如下： create table MY_COMPONENT ( ID uuid, VERSION integer not null, CREATE_TS timestamp, CREATED_BY varchar(50), UPDATE_TS timestamp, UPDATED_BY varchar(50), DELETE_TS timestamp, DELETED_BY varchar(50), DTYPE varchar(31), -- PRODUCT_NUMBER var
create table MY_COMPONENT (
ID uuid,
VERSION integer not null,
CREATE_TS timestamp,
CREATED_BY varchar(50),
UPDATE_TS timestamp,
UPDATED_BY varchar(50),
DELETE_TS timestamp,
DELETED_BY varchar(50),
DTYPE varchar(31),
--
PRODUCT_NUMBER varchar(255),
DESCRIPTION varchar(255),
MANUFACTURER varchar(100),
--
primary key (ID)
)
create unique index IDX_DEIPRODUCTCONFIG2_MY_COMPONENT_UK_PRODUCT_NUMBER
on DEIPRODUCTCONFIG2_MY_COMPONENT (PRODUCT_NUMBER) where DELETE_TS is null
alter table DEIPRODUCTCONFIG2_BASE add constraint FK_DEIPRODUCTCONFIG2_BASE_ID
foreign key (ID) references DEIPRODUCTCONFIG2_MY_COMPONENT(ID)
INSERT INTO BASE(ID, VERSION, PRODUCT_NUMBER, DESCRIPTION, MANUFACTURER);
BASE产品编号说明制造商MY\u组件NEWID（）myu组件中插入一行，并使用相同的ID
尝试插入BASE
。我也尝试了相反的方法，首先插入BASE
，然后使用其ID
插入MY\u组件。这两个都会引发有关唯一约束冲突的错误
我很清楚，我对数据库编程非常陌生。这些表和约束不是我创建的；我正在使用CUBA平台进行开发，这些表创建脚本是自动为我生成的。我确实理解CREATE语句的语法，但是外键的用途和用法我并不清楚。也许这就是我缺失的一环。但是任何指导都将不胜感激。我可能遗漏了一点，但我无法重现您的问题，在我的\u组件中插入然后基
对我来说似乎很有用
无论如何，如果要使用存储过程执行此操作，请参见：

你完全正确。我试图通过函数运行我的查询，以运行Cuba Studio内置的更新脚本。我将测试脚本移到了INIT_数据脚本中，Cuba在创建数据库时运行该脚本，并且成功插入了数据。我不确定这是否是他们这边的错误。谢谢你善良的灵魂。@不客气，如果你想一次完成双插入，我添加了一个存储过程；）
