surpress output of MySQL connection function

Hello,

I'm wondering if I can surpress the output of my function:

function [reference, suspect] = sqldata( host,db,user,password,reference_tbl,suspect_tbl) 

%%Create DB Connection

clear conn

conn = database(db, user, password, ...
                'com.mysql.jdbc.Driver', ...
                ['jdbc:mysql://' host ':3306/' db]);

%%Fetch Data            

setdbprefs('DataReturnFormat','cellarray');

e = exec(conn,['SELECT * FROM ' reference_tbl]);
e = fetch(e);
reference = e.Data;

e = exec(conn,['SELECT * FROM ' suspect_tbl]);
e = fetch(e);
suspect = e.Data;

end

using the ';' when using the function doesn't work however …

Help is greatly appreciated.

Which of the lines is producing the output ?

I suppose reference = e.Data and suspect = e.data

I figured out that when I manually 'clear all' and run the function then everything is fine. When doing that twice in a row, then data doesn't seem to be fetched but output appears. Although I have 'clear all' in my script as well but is being ignored. Connection is closes as well using close(conn).
