sql server - Query to get the accounts shows no movement in February 2016 and the balance is less than $ 2,000.00 -

-

i try make script query need in sql, try accounts showed no movement in specified month , balance less $ 2000 though try make in group by, not given me idea of how divide customers made movements among did not move accounts, because script this:

declare @fechamovimiento varchar(10) set @fechamovimiento = '0000-00-00'  if not exists (select * [dbo].[cuentasbancarias]                 inner join [dbo].[depositos] b                 on a.cuentaid = b.cuentaid                 inner join [dbo].[retiros] c                 on a.cuentaid = c.cuentaid                 b.fechamovimiento >= @fechamovimiento , b.fechamovimiento >= @fechamovimiento                  , c.fechamovimiento >= @fechamovimiento , c.fechamovimiento >= @fechamovimiento                 ) begin     raiserror('no existen clientes sin movimientos en el mes') end  if exists(select * [dbo].[cuentasbancarias]                 inner join [dbo].[depositos] b                 on a.cuentaid = b.cuentaid                 inner join [dbo].[retiros] c                 on a.cuentaid = c.cuentaid                 b.fechamovimiento >= @fechamovimiento , b.fechamovimiento >= @fechamovimiento                  , c.fechamovimiento >= @fechamovimiento , c.fechamovimiento >= @fechamovimiento                 --and a.saldo < 2000                 ) begin     select * [dbo].[cuentasbancarias] saldo <= 2000 end

and not correct, although data show, if customer made no move presents results, if single client made movement shows nothing ... , i'm super-confused ... admit not have many sql knowledge

and tried query too: 

select cb.* [dbo].[cuentasbancarias] cb not exists (select *               [dbo].[retiros] r               cb.cuentaid = r.cuentaid ,                     r.fechamovimiento >= '2016-02-01' ,                     r.fechamovimiento < '2016-03-01'               ) ,   not exists (select *           [dbo].[depositos] d           cb.cuentaid = d.cuentaid ,                 d.fechamovimiento >= '2016-02-01' ,                 d.fechamovimiento < '2016-03-01'           )          ,     exists (select * [dbo].[cuentasbancarias] saldo < 2000)

the tables in order:

accountbank

retiro/withdrawal

deposits

enter image description here

select cb.*   [dbo].[cuentasbancarias] cb  cb.saldo < 2000 ,   not exists (select *               [dbo].[retiros] r               cb.cuentaid = r.cuentaid ,                     r.fechamovimiento >= '2016-02-01' ,                     r.fechamovimiento < '2016-03-01'               ) ,   not exists (select *           [dbo].[depositos] d           cb.cuentaid = d.cuentaid ,                 d.fechamovimiento >= '2016-02-01' ,                 d.fechamovimiento < '2016-03-01'           )

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.
