java - Better to use TreeMap or order by? -

-

What will be a better programming practice?

Is the client better to use commands in SQL or results for things like dropdown in drop vs. hasp?

If you are thinking about performance, then better results in the end of the database Is solved, especially when the columns you sorted are indexed.

The performance difference for small data sets may not be significant, but I think that the order of the SQL command will be a simple approach in most cases.

Anyway you still have to use LinkedHashMap instead of plain Hasham if you should store previously pre-sorted data before using it in Maps. Since LinkedHashMap will place the data in an inclusion order, the hashmap will not be there.

If you want the data to be automatically sorted because it is placed in the map, then you will need a treemark or other sorted map implementation.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
