I am Using the Version "mysql-4.0.20d-win" on my Computer. But i am not able to Add or Insert a Foreign key.

My Query is like this:
DROP TABLE IF EXISTS `dept1`;

CREATE TABLE `dept1` (
`Dept_ID` int(5) NOT NULL default '0',
`Dept_Name` varchar(50) NOT NULL default '',
`Dept_Desc` varchar(150) default NULL,
PRIMARY KEY (Dept_ID)
)
ENGINE=InnoDB;


DROP TABLE IF EXISTS `master`;

CREATE TABLE `master` (
`Admission_ID` int(11) NOT NULL default '0',
`Adm_Start_Date` datetime NOT NULL default '0000-00-00 00:00:00',
`Adm_End_Date` datetime default NULL,
`Admission_Class` varchar(20) default NULL,
`Dept_ID` int(11) NOT NULL default '0',
`Ward_No` int(11) default '0',
PRIMARY KEY (Admission_ID),
CONSTRAINT 'admission_dept' FOREIGN KEY (Dept_ID) REFERENCES dept1(Dept_ID) ON DELETE SET NULL
)
ENGINE=InnoDB;


I get this Error:
[root@localhost:3306] ERROR 1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near ''admission_dept' FOREIGN KEY (Dept_ID) REFERENCES dept1(Dept_ID) ON DELETE SET NULL


Can u help me out in this situation?
