i seeing code, in have statement (char *)(emsg+1) given, i guess (char *) emsg might have been string, + 1 here? emsg pointer type (e.g. int ). emsg + 1 increments pointer 1, i.e. points initial address + sizeof(int) . then, (char*) (emsg + 1) cast, i.e. end result casted char* pointer, end pointer-to-char points initial address + sizeof(int) . in general, char* pointers characters, i.e. c -like 0 terminated strings, not case. convert pointer char* when want "extract" smallest unit of addressable memory, on machines char* pointer underlying type of 1 byte ( char ).

how defer constraint inside begin/end block? this works: sql> set constraint t_pk deferred; constraint set. but identical statement fails in begin/end block: sql> begin 2 set constraint t_pk deferred; 3 end; 4 / set constraint t_pk deferred; * error @ line 2: ora-06550: line 2, column 5: pl/sql: ora-00922: missing or invalid option ora-06550: line 2, column 1: pl/sql: sql statement ignored you need use execute immediate : begin execute immediate 'set constraint t_pk deferred'; end;

i have question template template parameters: let's consider following class: template<typename t, template<class, class=std::allocator<t> > class underlyingcontainertype = std::vector> class mycontainer { public: t value1; t value2; underlyingcontainertype<t> container; mycontainer() {} /* methods implementation goes here */ }; in example, mycontainer container chat uses underlying stl-compatible container whatever stuff. declaring underlying container type template template parameters, instead of regular template argument, allows handy usage of class mycontainer, such as: mycontainer<int> mcv; //implicitly using vector mycontainer<int, std::list> mcl; //no need write std::list<int> //template template parameters now, while work of stl-container, such std::vector, std::deque, std::list, , forth, not work, example, std::array provided in c++11. the reason ...
