Question

To catch an empty field out of my DB I use following code:

int score;
            if (c.isNull(11)) {
                score = 100;
            } else {
                score = c.getInt(11);
            }
            q.setScore(score);

But, it seems now that when I accidently have highlighted a cell in SQL Lite browser in the past, and export it (even left empty) it doesn’t appear as NULL anymore, but as ''
. I tried c.getInt(11) = ''but then again, this is not working…

Any ideas on how I could catch the '' as well?

If you are using getInt(), null and “empty” SQL values becomes 0 in Java (since null is not a valid Integer value), so use:

if(c.getInt(11) == 0) 

If this creates a logic problem since 0 might mean somthing else in your context, you can run an UPDATE command on your table to change every '' value to -1 in this particular column.
