You should be able to rotate through the Cursor and look for yourself:

mCursor = managedQuery(sms, null, null, null, null);

StringBuffer info = new StringBuffer();
for( int i = 0; i < mCursor.getColumnCount(); i++) {
    info.append("Column: " + mCursor.getColumnName(i) + "\n");
}
Toast.makeText(getApplicationContext(), info.toString(), Toast.LENGTH_LONG).show();
