Question

In my SQLite database manager I can query this:

SELECT SUM(odometer) as odometer FROM tripmileagetable where date like '2012-07%';

this query returns me the total sum of the odometer colum from the table named ‘tripmileagetable’ of the month of july 2012, but I want to write this code in android query.

But I can’t figure out how to establish this query in database.query() method, can any one help?

Answer 1

final Cursor cursor = db.rawQuery("SELECT SUM(odometer) as odometer FROM tripmileagetable where date like '2012-07%';", null);
int sum = 0;
if (cursor != null) {
    try {
        if (cursor.moveToFirst()) {
            sum = cursor.getInt(0);
        }
    } finally {
        cursor.close();
    }
}
