artificial intelligence - What is the meaning of <- in AI? -

-

I have seen lots of AI related items in the symbol & lt; -. For example, 

  delta & lt; - 0x & lt; - x + 1

etc.

I always assumed its meaning = (Assigment), but perhaps they have a meaning that is slightly different from the segment, I think?

Thank you

This is an assignment. It removes ambiguity that "=" The symbol adds, because this symbol is often overloaded to test equality.

It makes it very clear that the thing on the left side is being matched, corrected, integrated, or otherwise equals it.

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'
