python - mysql setting user name and password -

-

i have installed mysql on mac osx , can open in shell , gain access databases , tables come it.

now want create database in python using mysql-connector/python

before doing figured wise set user name , password in mysql.

i have tried using following error messages. goal set user name , password may provide mysql-connector python, , execute sql queries python environment. here tried @ mysql command prompt:

set password 'root'@'localhost' = password('newpwd');

and error message:

error 1044 (42000): access denied user ''@'localhost' database 'mysql'

so tried update method:

update mysql.user set password = password('newpwd') user = 'root';

and error message:

error 1142 (42000): update command denied user ''@'localhost' table 'user'

so know why denied , how can make changes create user , password may use in mysql connect in python environment?

sounds not authenticated. make sure authenticated root user

access denied user ''@'localhost' database 'mysql' should 

access denied user 'root'@'localhost' database 'mysql'

otherwise not logged in root, rather anonymous user.

ofc, when logged in root, won't message, username not have proper rights.

start query authentication

mysql -u username -ppassword -h hostnameorip databasename

example:

mysql --port=3307 --host=127.0.0.1 -u root --password=thisismypass test -e "load data low_priority local infile '%pathuser%' table `user_log`...."

in case 

 mysql -u root "set password 'root'@'localhost' = password('newpwd');"

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.
