DELIMITER ;

This sql query looks ok to me but I’m not understanding the error returned by phpmyadmin:

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 ‘IN iPatientMonitoringId BIGINT, IN

Answer 1

From: http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html

Note
Specifying a parameter as IN, OUT, or INOUT is valid only for a PROCEDURE. 
For a FUNCTION, parameters are always regarded as IN parameters.

Therefore, I believe you should drop the IN.

Try:

CREATE FUNCTION InsertEvent (iPatientMonitoringId BIGINT, iTypeId SMALLINT(6), 
iChannelId SMALLINT(6), iStart TIMESTAMP, iEnd TIMESTAMP) RETURNS BIGINT 
DETERMINISTIC
