How do I find the value of the value of 2-byte supplement value 0xFF72 "?

  1. Should I start 0xFF72 by binary convert?
  2. Bits backwards.
  3. Add binary notation to 1 // Here is lost.

I still do not know ..

In addition,

What is the value of an 8 byte double which is: 0x7FF8000000000000 Its value as a floating point?

f Meaning of 3 is only to add 1 value. Example with 0xFF72 (here 16 bits have been taken):

  1. First of all, reverse it: 0x008D (each digit just 0xF decreased original value Is

  2. then add 1: 0x008E

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'
