SQL Command truncated

[Hans Ari]

I wonder why this is happened, I want to figure out how to resolve this problem.

I develop an application using .Net 2005, and connect to MySQL server using ADO.net, connect as root.
I want to create some tables and triggers, but this is what I found.

Here's the problem :
I create a table named TblUser using SQL statement :
CREATE TABLE `workshop`.`TblUser`
(`userID` VARCHAR(10) NOT NULL DEFAULT '',
`username` VARCHAR(50) NOT NULL DEFAULT '',
`typeID` INT UNSIGNED NOT NULL DEFAULT 0,
`userPwd` VARCHAR(255) NOT NULL DEFAULT '',
`pwdHint` VARCHAR(255) NOT NULL DEFAULT '',
`userStatus` INT UNSIGNED NOT NULL DEFAULT 1,
`logID` INT UNSIGNED NOT NULL DEFAULT 0,
PRIMARY KEY(`userID`))ENGINE=MyIsam DEFAULT CHARSET=latin1;
The SQL statement executed successfully.

Next, I want to create a trigger after updating TblUser.userID using SQL statement :
CREATE TRIGGER `workshop`.`TblUser_after_update`
AFTER UPDATE ON TblUser
FOR EACH ROW BEGIN
UPDATE TblUserLog SET userID=NEW.userID WHERE userID=OLD.userID
UPDATE TblArrival SET acceptedBy=NEW.userID WHERE acceptedBy=OLD.userID
UPDATE TblAssignment SET assignedBy=NEW.userID WHERE assignedBy=OLD.userID
UPDATE TblAssignmentCompletion SET acceptedBy=NEW.userID WHERE acceptedBy=OLD.userID
UPDATE TblLeaving SET approvedBy=NEW.userID WHERE approvedBy=OLD.userID
END;
But, the statement produced an error :
ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.24-community-nt]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 'UPDATE TblUserLog SET userID=NEW.userID WHERE userID=OLD.userID
UPDATE TblArriv' at line 4

I tried it in MySQL Query Browser, and I had the same error too.

Can anybody help me ? I don't know whether this is a bug, or there is an error in my statement.
I'm sorry for my english, thanks for your intention.
