let’s say if this is my code

Cursor mCursor = dbAdapter.getAllTitles(); //returns results from 3 columns, eg column1, column2, column3

is there anyway I can assign the values from column1 to 1 string array, column2 to another and so on? perhaps like this

String[] getColumn1 = mCursor.dataFrom("column1");
String[] getColumn2 = mCursor.dataFrom("column2");
String[] getColumn3 = mCursor.dataFrom("column3");

examples i see to achieve the same result as above involves iterating through the values and put them into the respective array. too much resource consuming, no? then it’s better to make separate sql query for each columns, no?

    ArrayList<String> columnArray1 = new ArrayList<String>();
ArrayList<String> columnArray2 = new ArrayList<String>();
ArrayList<String> columnArray3 = new ArrayList<String>();
for(mCursor.moveToFirst(); mCursor.isAfterLast(); mCursor.moveToNext()) {
    columnArray1.add(mCursor.getString(COLUM_INDEX1));
    columnArray2.add(mCursor.getString(COLUM_INDEX2));
    columnArray3.add(mCursor.getString(COLUM_INDEX3));
}

    Afterwards you can convert the ArrayList into a String array:

    String[] colStrArr1 = (String[]) columnArray1.toArray(new String[columnArray1.size()]);
