memcpy - C++ equivalent for memset on char* -

-

मेरे पास यह कोड है 

  char * oldname = new char [strlen (name) + 1]; Memcpy (पुराना नाम, नाम, स्ट्रेलन (नाम) + 1); नाम = नया चार [स्ट्रेलन (पुराना नाम) + स्ट्रेलन (आर.नाम) + 1]; मेमसेट (नाम, '\ 0', स्ट्रेलन (नाम)); strcat (नाम, oldname); घुमंत (नाम, ""); strcat (नाम, r.name);

मैं समझता हूं कि यह मेम्कपी और मैमसेट का उपयोग करने के लिए कोई नहीं है, लेकिन मुझे यह समझ में नहीं आता कि वास्तव में सी ++ में इसका उपयोग कैसे करना है, अधिमानतः बिना एसटीडी।

किसी को पता है? धन्यवाद।

सामान्य तौर पर, std :: fill है।

या इस विशेष उदाहरण में, आपको std :: vector & lt; char & gt;

(ध्यान दें कि memset यदि आप #include & lt; cstring & gt; का उपयोग करते हैं तो भी C ++ में इसका उपयोग किया जा सकता है, हालांकि यह C ++ में कम मुहावरेदार 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'
