i have table contains null field. needs populated table. while statement getting information other table simple concerned performance of update. the update done script scheduled run every 30 minutes. which better: update using field null statement update table1 set freefield=(select name table2 table1.keyfield=table2.field) freefield null; update using statement updates last x records update table1 set freefield=(select name table2 table1.keyfield=table2.field) rowid in ( select rowid ( select keyfield table1 order keyfield desc ) rownum < 300 ); table1.keyfield , table2.field indexed , have primary/fk relation. table1.freefield , table2.name not indexed , text fields. currently table 100k record grow massively. i'm asking going take longer search null fields in table or order , use recent number specified. the final plan implement trigger records updated @ creation cannot implemented until next release of...

if classes below not templates have x in derived class. however, code below, have to use this->x . why? template <typename t> class base { protected: int x; }; template <typename t> class derived : public base<t> { public: int f() { return this->x; } }; int main() { derived<int> d; d.f(); return 0; } short answer: in order make x dependent name, lookup deferred until template parameter known. long answer: when compiler sees template, supposed perform checks immediately, without seeing template parameter. others deferred until parameter known. it's called two-phase compilation, , msvc doesn't it's required standard , implemented other major compilers. if like, compiler must compile template sees (to kind of internal parse tree representation), , defer compiling instantiation until later. the checks performed on template itself, rather on particular instantiations of it, require compiler able resolve...

i trying upload archive file taken through <input type=file> in html, calling servlet using javascript. in javascript trying mime type of it, giving type ""(means empty). how can identify whether archive? looks there isn't 1 mime type archives, each have own (if have 1 @ all). have this wikipedia article more info.

suppose have following tree: boost::property_tree::ptree tree; tree.add("1.2.3", "value-1"); tree.add("1.2.3.4", "nested-value"); tree.add("1.2.3", "value-2"); tree.add("1.2.33", "other-value"); which has following serialized info form: 1 { 2 { 3 value-1 { 4 nested-value } 3 value-2 33 other-value } } is there method remove nodes having provided (possibly nested) path? i.e.: remove(tree, "1.2.3"); boost_assert(!tree.get_optional<std::string>("1.2.3") && !tree.get_child_optional("1.2.3")); with result info form: 1 { 2 { 33 other-value } } looking @ ptree docs , source code i've found several methods remove immediate children of tree (nested children not accounted). also, there several methods subtree it's full path (even if nested). since th...

i have database, columns image , alttag. want use them in laravel blade view. try this: {{ html::image('images/{{ $item->image }}', $alt="{{ $item->alttag }}") }} but syntax isn't correct. if echo image , alttag this: <h1>{{ $item->alttag }}</h1> then correct. wonder wrong in code. you used blade syntax in php string. watch compiled blade templates see did go wrong. in short. try this: {{ html::image('images/'. $item->image, $alt = $item->alttag) }} or equally short: {{ html::image("images/{$item->image}", $alt = $item->alttag) }}
