i want data this:

enter image description here

i have found duplicate values using following query:

select a.[wallet] kycnew2   [dbo].[kycnew1] group a.[wallet]   having count(*) > 1

it has shown duplicate values. not have idea how make original , duplicate values , both of associated data side side. 1 me please?

a combination of row_number() , pivot this. you'll need know maximum number of duplicates before hand see everything.

select   account,   [1] path1,   [2] path2 (   select     account,     path,     row_number() on (partition account order path) r       dups   ) x pivot (   min(path)    r in ([1], [2]) ) piv

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
