QuestionMemory usage for requested rows from database Pin
Valentinor13-Jan-23 0:18

When you are running in Java:
ResultSet rs = stmt.executeQuery("SELECT Column FROM Table WHERE Condition");

Does the database create in memory a list with all the rows/values that have the given condition, and it is keeping that list until the rs is close? Or it will only keep the first value, and move to the next value when rs.next() is called?

I'm asking this because you can give it the command to FETCH NEXT X ROWS ONLY, and in case you have a database with millions of entries, that would save time and resources when you only want X rows, and not all of them that match the given condition.

Or the FETCH is only a hard limit to know when to stop with sending the rows/values one by one?
