Question

I have the following line of code to query the database, which has the value “ntd” to sort in date order.

public Cursor fetchAllReminders( String maybe) {

    return mDb.query(DATABASE_TABLE, new String[] {KEY_ROWID,
            NAME, START_DATE_TIME, NEXT_DATE_TIME, BILL_AMOUNT, OCC_AMOUNT, REF, NEXT_DATE_TIME_ACT, SUM_OCC, OCC_PERIOD, BIL_ACT, DATE_ACT, COUNTABLE, LAST, DDEBIT, ONE_OFF,ONE_OFF2 }, REF +"=?", new String[] { maybe }, null, null, "ntd", null);
}

Am I able to add another value so it first sorts by a boolean value then by the date value?

thanks

In the Android Developers Documentation the orderBy parameter to the SQLiteDatabase.query(...) method is described as follows:

How to order the rows, formatted as an SQL ORDER BY clause (excluding
the ORDER BY itself). Passing null will use the default sort order,
which may be unordered.

this implies that you can use any valid SQL ORDER BY clause, so you should be able to pass a comma delimitted list of the columns or expressions you wish to sort by, like this:

"some_boolean_column, ntd"
