SUM sqlite column values (android)

Question

I need help with summing all the values in one of the columns( KEY_CONTENT6 ) in my database( MYDATABASE_TABLE ). I keep having force close issues, somebody tell me what I'm doing wrong!

Heres my code:

public Cursor sumAll(){

 float columntotal = 0;
 Cursor cursor1 = sqLiteDatabase.rawQuery(
     "SELECT SUM("+Float.valueOf(KEY_CONTENT6)+") FROM MYDATABASE_TABLE", null);
       if(cursor1.moveToFirst()) {
         columntotal = cursor1.getFloat(0);
     }
   cursor1.close();

 String  sumtotal = Float.toString((float)columntotal);           

  return cursor1;

 }

The column KEY_CONTENT6 is a string for various reasons which is why I used Float.valueOf() but I'm guessing that's where my problem is.

Answer 1

You're closing the cursor then returning it. You probably want to return the column total or sum total, not the cursor
