Getting Data from Cursor

Question

What I need to do is get the Points for a certain User in a certain Shop, I run this;

                Cursor cursor1 = myDB.checkPointss(email, name);
                String one = cursor1.getString(cursor1.getColumnIndex("POINTS"));

                scanText.setText("barcode resueeeelt " + one);

This is the Method;

public Cursor checkPointss(String email, String name) {
    Cursor c = db.rawQuery("SELECT * FROM compdata WHERE EMAIL= ? AND NAME=?", new String[] {email, name});
    if (c != null) {
        c.moveToFirst();
    }
    return c;

}

Everytime I try Login to the page, it crashes over trying to get the points? I've tried so many different codes but none seem to work.

So I just want it to find the points for the row that contains that username and shop name, then add a certain amount to the points and update the database.

THIS WORKS;

public boolean checkPoints(String email, String name){
    Cursor c = db.rawQuery("SELECT POINTS FROM compdata WHERE EMAIL= ? AND NAME=?", new String[] {email, name});
    if(c.moveToFirst()) {
        return true;
    }  else {
        return false;

    }
}

So why doesn't it work to get the data?

Answer 1

getColumnIndex() is case sensitive while SQL is not.

If the column is lowercase in the table, it will be lowercase in the SELECT * result set, and trying to retrieve it with uppercase column name won't work.
