mysql - SQL commands not compliable by H2 -

-

the following sql commands mysql. not sql expert , not know h2. spring app throws exception because user_roles table can not created. has problem fk_username_idx:

  drop table if exists users;   drop table if exists user_roles;    create  table users (   userid varchar(5) not null,   username varchar(45) not null ,   password varchar(60) not null ,   enabled tinyint not null default 1 ,   primary key (userid));       create table user_roles (   user_role_id int(11) not null auto_increment,   userid varchar(5) not null,   role varchar(45) not null,   primary key (user_role_id),   unique key uni_username_role (role,userid),   key fk_username_idx (userid),   constraint fk_username foreign key (userid) references users (userid));

error log:

  1. are sure h2 runs in mysql compatiblity mode? check first. looking @ connect string. example this:

    final simpledriverdatasource ds = new simpledriverdatasource(); ds.setdriverclass(driver.class); ds.seturl("jdbc:h2:mem:test;mode=mysql;db_close_delay=-1;db_close_on_exit=false"); ds.setusername("sa"); ds.setpassword("");

  2. foreign key fk_username_idx (userid), not suppported h2. remove foreign here.

then work

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.
