java - Statement.execute(sql) vs executeUpdate(sql) and executeQuery(sql) -

i have question related method: st.execute(sql); st statement object. directly this oracle java tutorial: execute: returns true if first object query returns resultset object. use method if query return 1 or more resultset objects. retrieve resultset objects returned query repeatedly calling statement.getresutset. what meant " one or more resultset objects "? how possible manage them once got array of resultset ? whereas st.executequery(sql) , st.executeupdate(sql) clear. it's not (at least me) aim of st.execute(sql) can return int if updated table. thanks in advance what mean "one or more resultset objects"? the javadoc execute method says this: " executes given sql statement, may return multiple results. in (uncommon) situations, single sql statement may return multiple result sets and/or update counts. can ignore unless (1) executing stored procedure know may return multiple results or (2) dynamically execut

c++ - How to emulate a variable template as a class member? -

i'd have opinion on how emulate variable template class member. having data member in class dependent on template, not on class template. conceptually, written : class m { private: template<typename t> somethingthatcoulddependont<t> m_datamember; }; my first thought make : #include <iostream> class { public : template<typename t> void mymethod() { static int = 0; std::cout << "my method : " << << " calls" << std::endl; a++; } }; int main() { a, b; a.mymethod<int>(); a.mymethod<int>(); a.mymethod<double>(); b.mymethod<double>(); return 0; } but doesn't work because static member in mymethod isn't per instance per method generated. actually, makes sense mymethod can seen global function taking first parameter object of type (without taking account visibility concerns). came other idea : #include

grep - Why does this regex not work for matching C integer declarations? -

i'm using following regular expression match c integer declarations without initialization. integer might unsigned: ^(unsigned[[:space:]]+|^$)int[[:space:]]+[a-za-z0-9_]+;$ the first part matches unsigned followed number of spaces, or nothing. second part matches int followed spaces, plus variable name , semicolon. unfortunately, seems not match integer declaration doesn't have unsigned in it. doing wrong? ^$ in (...|...) pattern expect (match empty string)? google , regex manual isn't helping. try this: ^[[:space:]]*(unsigned[[:space:]]+)?int[[:space:]]+[a-za-z0-9_]+;[[:space:]]*$ to make group optional, put ? after it. ^$ doesn't match empty string in middle of match, matches entirely empty string -- ^ matches beginning of string, , $ matches end of string.

ruby - How does module_eval / class_eval / instance_eval counts the line numbers -

i have found line_number passed class_eval , module_eval , instance_eval doesn't match line numbers reported error. behaviour not explained ruby-doc says: (use instance_eval example) the optional second , third parameters supply filename , starting line number used when reporting compilation errors. all these 3 methods class_eval , module_eval , instance_eval accepts 2 additional params specify filename , lineno parameters set text error messages. this question has practical demo behavior. however, have found calculation of line numbers more complex explanation. here demo class thing def add_method = %{ non_exist } instance_eval(a, 'dummy', 12) end end # error raise 15 instead of 12 specified puts thing.new.add_method the code above proves line_no param passed instance_eval not line numbers reported error related line_no . i wondering exact behavior of params? as snippet of documentation states, lineno spec

c - How is exit status passed between pthread_exit and pthread_join? Is a correction needed in man page? -

question: how exit status passed between pthread_exit , pthread_join? from pthread_join man page int pthread_join(pthread_t thread, void **retval); if retval not null, pthread_join() copies exit status of target thread (i.e., value target thread supplied pthread_exit(3)) location pointed *retval. if target thread canceled, pthread_canceled placed in *retval. i think wording in man page incorrect. it should "if retval not null, pthread_join() copies address of variable holding exit status of target thread (i.e., value target thread supplied pthread_exit(3)) location pointed retval." i wrote code shows this, see code comments: #include<stdio.h> #include<stdlib.h> #include<pthread.h> void * function(void*); int main() { pthread_t thread; int arg = 991; int * status; // notice did not intialize status, status *retval pthread_create(&thread, null, function, (void*)(&a
