What would be better in terms of memory efficiency or would have the best overall performance on Android and SQLite, getting a record count with cursor.getCount() or to execute a rawQuery with a COUNT on a normal SQL clause (and use cursor.getInt(0) later to get the count returned)?
Note: I’m not using the results, I just want the count.
If you are using the result of the query afterwards, then of course the best way would be to do
cursor.getCount()This is faster than doing 2 queries one to get the count and one for the resultEDIT :
If you are not using the results, then a rawQuery is faster because you are gettting only one column from the database instead of many. Plus why would you waste resources to execute a query and not use its result?
