sql - How to know that MERGE operation was INSERT or UPDATE? -

-

let have,

merge share_ad_group using (     select share_ad_group_id,         share_id,         ad_group,         share_permissions     share_ad_group     share_id = @shareid , ad_group = @ownerid ) b on (a.share_ad_group_id = b.share_ad_group_id) when matched     update set a.share_permissions = b.share_permissions when not matched     insert (share_permissions) values(@sharepermissions);  -- in here how know insert or update

how know merge operation insert or update after insert or update?

please refer here

declare @summaryofchanges table(change varchar(20));  merge tbltarget target using (select col1,col2 tblsource)      source on (target.col1 = source.col1) when matched      update set target.col2 = source.col2 -- need affected rows here when not matched target     insert (col1,col2) values (col1,col2); -- need affected rows here output $action @summaryofchanges;  select change, count(*) countperchange @summaryofchanges group change;

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.
