ms access - Unable to Group on MSAccess SQL multiple search query -

-

please can me before go out of mind. i've spent while on , resorted asking helpful wonderful people. have search query:

select  groups.groupid,          groups.groupname,          (   select  sum(siterates.sitemonthlysalesvalue)                 siterates                invoicesites.siteid = siterates.siteid         ) sumofsiterates,          (   select  count(invoicesites.siteid)                 invoicesites                siterates.siteid = invoicesites.siteid         ) countofsites    (invoicesites          inner join (groups              inner join sitesandgroups                  on groups.groupid = sitesandgroups.groupid         ) on invoicesites.siteid = sitesandgroups.siteid)          inner join siterates              on invoicesites.siteid = siterates.siteid group groups.groupid

with following table relationship

without group entry can list of entries want drills results down siteid instead want group groupid. know possible lack expertise complete this.

any massively appreciated.

i think need add groups.name group by clause, adopt different approach , try avoid subqueries if possible. since have joined required tables can use normal aggregate functions:

select  groups.groupid,          groups.groupname,          sum(siterates.sitemonthlysalesvalue) sumofsiterates,          count(invoicesites.siteid) countofsites    (invoicesites          inner join (groups              inner join sitesandgroups                  on groups.groupid = sitesandgroups.groupid         )   on invoicesites.siteid = sitesandgroups.siteid)          inner join siterates              on invoicesites.siteid = siterates.siteid group groups.groupid, groups.groupname;

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.
