XML parsing unable to switch the encoding

When i tried to query a ntext column as xml with CAST function i had :

XML parsing: line 1, character 55, unable to switch the encoding

error. i did some research finally i succeed on it

Ex :

SELECT
colum1,
column2,
CAST(REPLACE(CAST(column3 AS NVARCHAR(MAX)),'utf-8','utf-16') AS XML)
FROM TABLE1

column3 : is ntext xml data which has
at the top of root element

1. Convert ntext to nvarchar for replace function (doesn't accept ntext datatype)
2. Replace 'utf-8' text with 'utf-16' because of SQL Server 2005 restrict
3.Cast result to XML and have fun :)

Thanks, very helpful! I just wanted to add that it doesn't work when there are ampersands in the XML…one small change fixes that:

CAST(REPLACE( REPLACE([column3],'utf-8','utf-16'), '&', '&') AS XML)

Detailed information, api documentation and examples can be found in https://d3js.org address. In this article i try to show some of features whose are fundamentals of the library.  First of all we will start with adding javascript library reference with following sentence  This is the minified version of the js file which can also be used non-minified version. Purpose of this to minimise page load waiting and data throughput  The following bar-chart was created by d3.js library. I will try to explain how can accomplish this simple bar-chart via d3.js First of all we have to add d3.js file to our html file and add svg html element which is crucial for d3 shapes and other things.

HTML Vector Graphic PATH element

Image
The path is powerful vector graphic element and it can be used drawing lines, curves etc.  We can create complex shapes with using it.  In this example i will show you how we simple draw a line with path element. We have to use SVG element as container and its height and width will be 200 pixels.     By the way coordinate system of the HTML is little bit different from known coordinate system.   Opposite of the known system positive Y axes are down side. Path element has d attribute which is used for line direction curve and for other commands. In our simple example d has M and L. M means move, it also starting point of the path. L means draw line to a point. Our code  generates following output We start with x:20, y:20 point and draw line to x:60, y:20 point and finally draw line to x:60, y:200 point.
