c++ - inline virtual function -

-

In C ++, my understanding is that the virtual function can be underlined, but in general, The signal is ignored. It seems that inline virtual functions do not matter too much.

Is that correct?

Can anyone make a case in which an inline virtual function is good?

By having this happen, a virtual function call can only be generated inline if the compiler can determine the actual type for which the function will be used. , Instead it should be something derived from Class X or X.

An inline virtual function is understood in primary time, if you have a performance critical position, and know that a class will often be used in a manner that determines the compiler for the actual type (And optimizes the call through at least one target compiler pointer)

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'
