Hi,
x=TOYOTA;
Y=9981;
conn = database('baza_date','','');
sqlquery = ['UPDATE prices.prices SET Product =',num2str(x), 'WHERE Crt = ', num2str(y)];
data = fetch(conn,sqlquery);
exec(conn,sqlquery);
close(conn);
Error:
Error using database/fetch (line 40)
[MySQL][ODBC 8.0(a) Driver][mysqld-8.0.29]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 'Crt = 9981' at line 1
Error in bdmodify>pushbutton12_Callback (line 509)
data = fetch(conn,sqlquery);
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in bdmodify (line 42)
gui_mainfcn(gui_State, varargin{:});
If I use a single variable for query it worked if I use both i recieve this error, i guess i didn't write the code ok, do you know?

I suspect you're missing a space before 'WHERE'. I can recommend using sprintf to avoid such errors.
