Question

I looked for this on SO and saw this(and others like it): sql direct way to get number of rows in table, however, Select is shown as a token as is count. I tried to use mDb.execSQL() but that only returns void. Any help on how to do this would be appreciated. The code is:
public int getRowNumber(){ return mDb.execSQL(“SELECT COUNT(*) FROM notes”);} I get an error that says “cannot return void result”.

Answer 1

The error you’re getting means your method can’t return void. execSQL itself returns a void, and you’re returning that same void from your own method which is declared to return an int:

mDB.execSQL(...); // returns void
return mDB.execSQL(...); // re-returns void

public int foo() {
    return void; // error!
}

d.android.com link for reference.

I know you already accepted, but here’s a quick & dirty test method that does what you sort of need to do:

    public int testCount() {
     Cursor c = m_db.rawQuery("select count(*) from mytable", null);
     int tst = 0;
     if (c.moveToNext()) {
         tst = c.getInt(c.getColumnIndex("count(*)"));
     }
     c.close();
     return tst;
  }
