[英]Foreign key reference to a new schema
我想将一些表移动到新的架构。 移动它时,外键引用出现错误。 我也尝试授予权限。 帐户是地址表所在的旧模式,我将地址移到了称为地址的新模式。 我得到错误表或视图不存在:
CREATE TABLE ACCOUNTS.PARTY_ADDRESS
(
PARTY_ID NUMBER(18,0),
ADDRESS_ID NUMBER(18,0),
CONSTRAINT PARTY_ADDRESS_PK PRIMARY KEY (PARTY_ID, ADDRESS_ID),
constraint PARTY_ADDRESS_party_fk foreign key (PARTY_ID)
references PARTY(id),
constraint PARTY_ADDRESS_ADDRESS_UNQ unique (ADDRESS_ID)
);
ALTER TABLE ACCOUNTS.PARTY_ADDRESS ADD CONSTRAINT PARTY_ADDRESS_address_fk FOREIGN KEY (ADDRESS_ID) REFERENCES ADDRESS.ADDRESS(id);
我还提供了以下地址的赠款:
GRANT ALL ON ADDRESS.ADDRESS TO ACCOUNTS;
REFERENCES
一个架构能够创建对另一个架构中的表的引用约束,必须具有表特权REFERENCES
。 GRANT ALL
应该已经工作了。 在我的测试案例中,它确实有效,例如:
模式1:
create table schema1.t1 (id number primary key);
Table T1 created.
模式2:
create table schema2.t2 (id number primary key, fk number);
Table T2 created.
alter table schema2.t2 add constraint fktest
foreign key (fk) references schema1.t1 (id);
ORA-00942: table or view does not exist
模式1:
grant references on schema1.t1 to schema2;
Grant succeeded.
模式2:
alter table schema2.t2 add constraint fktest
foreign key (fk) references schema1.t1 (id);
Table T2 altered.
模式1:
revoke references on schema1.t1 from schema2;
ORA-01981: CASCADE CONSTRAINTS must be specified to perform this revoke
revoke references on schema1.t1 from schema2 cascade constraints;
Revoke succeeded.
如果您GRANT ALL
它也可以使用:
模式1:
grant all on schema1.t1 to schema2;
Grant succeeded.
模式2:
alter table schema2.t2 add constraint fktest
foreign key (fk) references schema1.t1 (id);
Table T2 altered.
