解决方法

声明内联外键的语法为：

<column_name> <datatype> references <parent_table(parent_column_name)>

基本上就是这样：

empid number foreign key references employee_dimension(empid)

应写为：

empid number references employee_dimension(empid)

或者，您可以在单独的子句中声明外键，这使您有机会选择键的名称（与内联语法相反，后者由数据库自动选择名称）：

empid number,constraint empid_fk foreign key references employee_dimension(empid)

,

尝试为

CREATE TABLE sale_facttable
(
   empid         NUMBER    REFERENCES employee_dimension (empid),productnum    NUMBER    REFERENCES product_dimension (productnum),suppliernum   NUMBER    REFERENCES supplier_dimension (suppliernum),saleid        NUMBER    REFERENCES sale (saleid),clerkid       NUMBER    REFERENCES sale_clerk_dimension (clerkid),productid     NUMBER    REFERENCES product_dimension (productid),branchid      NUMBER    REFERENCES branch_dimension (branchid),lineid        NUMBER    REFERENCES sale_line_item_dimension (lineid),customerid    NUMBER    REFERENCES customer_dimension (customerid),saledate      DATE    REFERENCES sale_line_item_dimension (saledate)
);
