我有两个模式，我们称它们为 BOB 和 FRED。我需要从架构 BOB 调用架构 FRED 中的一个表，以将该表中的主键用作外键。我已经为模式 FRED 设置了适当的授权以允许 BOB 访问它，但是每当我运行脚本时，它都会抱怨我没有正确的权限。我需要在某处更改其他设置吗？这甚至可以做到吗？

我的FK创作如下：

ALTER TABLE "BOB"."ITEMGROUP" WITH CHECK ADD CONSTRAINT FK_ITEMS_ITEM FOREIGN KEY (ItemID)
REFERENCES "FRED"."ITEMS"(ItemID)

我正在通过以下方式进行赠款：

GRANT ALTER ON "FRED"."ITEMS" TO "BOB"

我收到此错误消息：

SQL Error: ORA-01031: insufficient privileges 
01031. 00000 -  "insufficient privileges"

*Cause:    An attempt was made to change the current username or password
           without the appropriate privilege. This error also occurs if
           attempting to install a database without the necessary operating
           system privileges.
           When Trusted Oracle is configure in DBMS MAC, this error may occur
           if the user was granted the necessary privilege at a higher label
           than the current login.

*Action:   Ask the database administrator to perform the operation or grant
           the required privileges.
           For Trusted Oracle users getting this error although granted the
           the appropriate privilege at a higher label, ask the database
           administrator to regrant the privilege at the appropriate label.

你需要：

grant references on "FRED"."ITEMS" TO "BOB"

要创建引用另一个模式中的表的外键，您需要“REFERENCES”权限：

GRANT REFERENCES ON FRED.ITEMS TO BOB;
