variables - what kind of datatype should i use for this 600851475143 in c++? -

-

I am using c ++, even though I declare long int, there is an error like that. .... 

  long int number = 600851475143; WARNING: The integer for the 'long' type

is very long continuous, in which case what datatype should be used?

It depends on a lot of platforms and compilers that you are using.

If you are on an x64 platform, then a long datatype should work in C ++. 9223,372,036,854,775,808 to 9,223,372,036,854,775,807 with a long-signed category on the other hand an unsigned long time between 0 to +18,446,744,073,70 9,551,615

Apart from this, there are some other datatypes based on the compiler and platform, which are effectively the same thing (doubleword, landed, long long, quad, quadword, int64).

C (not C ++) supports long long data types. Say if you are on Fedora 10 x32, then GCC 4.3.0 supports long datatype, but you should put the URL after the big word.

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'
