我更改了标签。 “ORA-00907”错误适用于 Oracle，而不是 MySQL。 NUMBER 也是 Oracle 数据类型，MySQL 无法识别。
您混淆了语法。取出所有FOREIGN KEY文字；或者将 FK 单独构建到列定义中。
您好，请在发布问题时提供一些描述。顺便说一句，这是一个非常常见的问题 (ORA-00907)。这篇文章为这个问题提供了一组可靠的答案，stackoverflow.com/questions/48045336/…。

【解决方案1】：

声明内联外键的语法是：

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

所以基本上是这样的：

empid number foreign key references employee_dimension(empid)

应该写成：

empid number references employee_dimension(empid)

或者，您可以在单独的子句中声明外键，这样您就有机会选择键的名称（与内联语法相反，其中名称由数据库自动选择）：

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

【解决方案2】：

试试

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)
);
