php - How do I insert into database with codeigniter without it putting the single quotes? -

-

i'm making feature in app users can select multiple db items , change department belong @ once. have in codeigniter model currently:

function  multimove($dept, $jobstring) {     $sql = "update jobs set department = ? id in(?)";     $this->db->query($sql, array($jobstring, $dept));      echo $this->db->last_query(); }

the function takes in 2 values department number , id's of selected jobs. i'm trying achieve sql function:

update jobs set department = 3 id in(5,6,48);

but codeigniter generates this:

update jobs set department = '3' id in('5,6,48');

it puts single quotes on values , creates errors. there way around this?

calling model

$this->load->model('model_jobs'); $this->model_jobs->multimove(3,'2,3,8');

model

function multimove($dept,$jobstring) {        $ids = explode(",",$jobstring);     $upd_data = array('department' => $dept );     $this->db->where_in('id', $ids);     $this->db->update('test', $upd_data);      echo $this->db->last_query(); }

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
