mysqld-nt4.0.12上add foreign key 出现问题！

st.linux.ily

the two tables are:
create table `customer` (
`Customer ID` int(10) not null default `0`,
`Company` varchar(50) default null,
`Email` varchar(50) default null,
primary key (`Customer ID`)
)type=innodb

create table `services` (
`Services ID` int(10) not null default `0`,
`Customer ID` int(10) default null,
`Services Date` timestamp(14) not null,
`Problem` blob,
primary key (`Services ID`),
key `Customer` (`Customer ID`)
)type=innodb

当我执行：
alter table services
add foreign key (`Customer ID`) references `customer`.`Customer ID` on delete cascade
or
alter table services
add foreign key (`Customer ID`) references customer(`Customer ID`) on delete cascade

但是出现下述错误：
Error Code : 1005
Can't create table '.\pc\#sql-15b0_1.frm' (errno: 150)
(0 ms taken)


有人说是：
Apparently InnoDB doesn't like to have the same column names in a relationship. So, change one of the `Customer ID` column names to something else and there you go.

所以我就改了，在原来的两个表的基础上执行：
alter `customer` change `Customer ID` `CustomerID` INT(10) DEFAULT `0` NOT NULL;

再执行：
alter table services
add foreign key(`CustomerID`) references customer(`Customer ID`) on delete cascade;

但是仍然有：
ERROR 1005: Can't create table '.\pc\#sql-834_14.frm' (errno: 150)

我该怎么办？该功能在mysql 中到底能不能实现！？
