Today, one of my colleges getting an error in Joomla admin – “JFolder::folder: Path is not a folder“ . We’ve tried lots of thing but cannot resolve, finally we’ve found the below solution.

Please remove the cache from cache folder or make a new cache folder.

Thanks.

I have tried to remove the duplicate rows from the table using row_number function. Here I am explaining the demo using the temp table.

Steps:

1. Create Temp Table or Select your table

Create Table #Main

(

id int,

item varchar(100)

)

2. Insert some records

insert into #main values (119,1)

insert into #main values (119,2)

insert into #main values (119,2)

insert into #main values (119,3)

insert into #main values (119,3)

insert into #main values (119,4)

insert into #main values (119,5)

insert into #main values (119,6)

insert into #main values (119,7)

insert into #main values (119,8)

insert into #main values (119,8)

insert into #main values (119,8)

3. expected Output

–Output

–119 1

–119 2

–119 3

–119 4

–119 5

–119 6

–119 7

–119 8

4. first we have start to get single records

–we got those record which count =1

select id,item from

(

select *,

(select count(item) as NoOfCount from #Main where item =Mst.Item group by id,item) as NCount

from #Main Mst

)a

where NCount =1

5. Result 1

–Result

–119  1

–119  4

–119  5

–119  6

–119  7

6. Now find the records where item count is >1

–we got those record which count >1

select id,item from

(

select id,item,ROW_NUMBER()Over(Partition by Item Order by Item) As Rep

from

(

select *,

(select count(item) as NoOfCount from #Main where item =Mst.Item group by id,item) as NCount

from #Main Mst

)a where NCount>1

)RepT where rep=1

7. Result 2

–Result

–119  2

–119  3

–119  8

8. Result 1 Union Result 2

9. Output

–Result

–119  1

–119  4

–119  5

–119  6

–119  7

–119  2

–119  3

–119  8

What is HierarchIyd Data Type? 

HierarchyId data type is a variable length System Data Type.

What is the use of HierarchyId Data Type?

Represent position in a hierarchy manner.

HierarchyId does not automatically represent a tree, it is depend on how to application generate and assign HierarchyId values.

HierarchyId have following properties:

1) Extremely Compact

2) Comparison is in depth-first-order.

3) Support for arbitrary insertions and deletions.

Limitation Of HierarchyId :

1)  Does not automatically represent a Tree

2) It is up to Application to manage concurrency in generating and assigning HierarchyId Values.

3) There is no any dependency on HierarchyId relationship.

See more about HierarchyId example refer :

http://amitpatriwala.wordpress.com/2009/10/23/sql-server-2008-feature-part1/

Reference Site :

http://technet.microsoft.com/en-us/library/bb677290.aspx

1) Initializing variable when you declare

declare @val as int =0
declare @currentdate as datetime = getdate()
print @val
print @currentdate

2) Compound assignment operators

–operator like +=,-=,/=,*/,%=
declare @val as int = 0
set @val += 10;
print @val

3) Add multiple row in single Insert Statement

CREATE TABLE Employee
(
EmpId int,
EmpCode varchar(50),
EmpName varchar(50)
);

INSERT INTO Employee(EmpId, EmpCode,EmpName)
  VALUES
  (1, 'emp1','emp1'),
  (2, 'emp1','emp1'),
  (3, 'emp1','emp1');

select * from Employee

4) New Data Types

   2: CREATE TABLE Employee

   4: EmpId int,

Inserted Data Into Table 

Different Selection Criteria :

1) Find Employee As Per their Level means Grade 

   select * from Employee where Emplevel = 2

2) Get Child Node 

   SELECT Child.empid, Child.empname FROM Employee AS Parent JOIN Employee AS Child
          ON Parent.empid = 2 AND child.empbossid.IsDescendantOf(Parent.empbossid) = 1;

3) Get Parent Node

SELECT parent.empid, parent.empname
  FROM Employee AS Parent JOIN Employee AS Child
    ON child.empid = 4 AND child.empbossid.IsDescendantOf(Parent.empbossid) = 1;

more on HierarchyId Data Types refer:

http://amitpatriwala.wordpress.com/2009/10/23/hierarchyid-data-type/

5) Introduced New Functions

6) Support Large User Define Types [UDT]

Sql Server 2008 supports large UDT,large UDTs can now reach up to 2 GB in size.

URL rewriting is the process of intercepting an incoming Web request and redirecting the request to a different resource. When performing URL rewriting, typically the URL being requested is checked and, based on its value, the request is redirected to a different URL.

http://msdn.microsoft.com/en-us/library/ms972974.aspx 

why URL rewriting?

1) Make User Friendly and Secure URL

Example :  In your application, you create a page which display category information and it’s relevant category. At that time we normally passing a value via query string,

http://Site.com/category.aspx?categoryid=1. Any user play with URL, you can also do the URL Encryption. but sometime case is complex at that time it is not possible.

2) Make SEO Friendly URL

3) Usability & Maintainability

Use Of Browser file?

ASP.NET uses .browser files to determine the capabilities of the browser, and how to render markup to that browser.

Browser files are used to reduce the load of the page made by the view state by storing it in a server side session variable.

In particular Rewriting Module: Handling Post back with URL Rewriting.

what is ControlAdapter?

for more detail please check :

http://msdn.microsoft.com/en-us/library/system.web.ui.adapters.controladapter.aspx

Create demo project for URL Rewriting:

Step 1:

Create Web application with (Asp.net 2.0 with c#)

Step 2:

Put two button in the form (default.aspx)

Put Below code for Button1_Click Event :

Response.Redirect("Default.aspx?id=1");

Put Below code for Button2 _Click Event:

Response.Redirect("/urlrewriting/FirstSection/Default.html");

Step 3: Run Application

once you press Button2 it give Error page.
