c++ - Generating a unique id of std::string -

-

मैं 32 बिट अनुप्रयोग में कोई भी सीमित std :: string size unique id (i.e आकार 6) उत्पन्न करना चाहता हूं। ऐसा करने का सबसे अच्छा और तेज़ तरीका क्या होगा?

स्ट्रिंग्स की हैशिंग की तलाश करें, उदा। ।

लेकिन आप कभी नहीं अद्वितीय हैश प्राप्त करेंगे, क्योंकि तार आपके आकार 6 से अधिक लंबा हो सकते हैं, और शो में कम से कम हो सकता है कि चाहिए टकराने जैसा परिणाम है।

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'
