HI ..
Id and password are int data type in database
I want to check if the id and password entered by user are in database.
Code:
a = get(handles.Id,'String');
b = get(handles.password,'String');
conn = database.ODBCConnection('users','root','root');
x = exec(conn,'select ID from Admin');
y = exec(conn,'select Password from Admin');
x = fetch(x);
y = fetch(y);
x1 = x.Data
y1 = y.Data
L1 = strcmp(a,x1)
L2= strcmp(b,x1)
if L1 == 1 && L2 == 1
track
else
msgbox('Rong ID or Password ! ');
end
I trired to convert x1 and y1 to string
x2 = num2str(x1);
I get this error:
Input to num2str must be numeric.
I know that x1 is cell but I don't know how can I do it !
Can you please help me?

Except for SQLite, it is possible to configure the database as to what datatype is to be returned by fetch (SQLite always returns the same datatype, and that is not the same datatype as the default for other databases.)
I suspect that if you check class(x1) that you will find that it is a 1 x 1 cell array containing a numeric value. Another possibility is that it might be a struct containing the field 'ID' .

Using curly brackets, x1{1} will give you the numeric value inside the cell :)
