fetching data from access database in MATLAB R2015b - Reg

I executed a query in MATLAB R 2013a with the following code.

conn = database('MultiProductInventory','admin','admin');
  query1 = ['SELECT ALL ID FROM "stocks" WHERE PI=',num2str(x(1))];
       query2=[''];
    for fidx=1:8      
      query2 = strcat(query2,sprintf('and F%d=',fidx),num2str(x(fidx+1)));
      end
    query3 = strcat(query1,query2);
        curs=exec(conn,query3);
curs=fetch(curs);
y1= curs.Data;

It worked well in MATLAB R2013a. The same query when i tried to execute in MATLAB R 2015b. It is displaying the error message:Undefined function fetch for input argument of type struct. what changes i should make to execute the query in R2015b.
