Strip HTML Encoding Out Of A String In Sql Clr
Apr 3, 2008
I am trying to do string scrubbing in a sql clr function, including removing certain HTML formatting. I would like to use HtmlDecode method, but it's my understanding that System.Web is not available for Sql Clr (without marking code unsafe - not an option for me as this is for an application we sell externally, and unsafe calls woudl not go over well with customers). Is there any class that IS supported for Sql Clr that exposes this functionality? Thanks.

I had a problem with the ntext datatype. I need to strip the HTML tags out of a ntext datatype column. I have sample query for that, which works fine for STRING, as stuff is the string function, what to do for ntext field.

I have a column of 5 comma-separated-value strings:
stringA, stringB, stringC, stringD, stringE
The strings are GUID's with the hyphen stripped and made all uppercase so they are completely random. I need to be able to remove any one of the strings including the comma, in a stored procedure and I am not sure how to accomplish this.
SELECT tickets
FROM users
WHERE CONTAINS (tickets, @ticket)
IF @@rowcount > 0
REMOVE STUFF HERE
SET @valid = 1
ELSE
SET @valid = 0
So if stringB gets passed in as @ticket then the new value in the column would be :
stringA, stringC, stringD, stringE
Any help is greatly appreciated.
Thank you

I'm trying to find a way to strip text from a string. In the past (pre SQL Server) I would've used
LName: Left(NCBH!Name,InStr(1,NCBH!NAME,",",1)-1)
To strip the last name from a string like
Franks,George J
Apparently InStr is not a recognized function in SQL Server 2000. Or is it available but not in a view?
Any thoughts would be greatly appreciated.

I have a phone number string (416) 555-5555 in a table. I'd like to perform a search on the string so that the user is able to pass any number, and the query returns all phone numbers like it. What I'd like to do is to strip out the brackets and dashes and perform a like search.

I am looking for the fastest way to strip non-numeric characters from a string.
I have a user database that has a column (USER_TELNO) in which the user can drop a telephone number (for example '+31 (0)12-123 456'). An extra computed column (FORMATTED_TELNO) should contain the formatted telephone number (31012123456 in the example)
Note: the column FORMATTED_TELNO must be indexed, so the UDF in the computed column has WITH SCHEMABINDING.... I think this implicates that a CLR call won't work....

We have a "Comment" field that is saved as a HTML string to the DB. This field needs to be pulled into a report as rendered HTML.
I know this has been hashed out before, but has anybody found a good solution in the past couple of months?
We are thinking about storing two versions of the Comment in the DB: one with HTML, one as simple text. Has anybody found this an acceptable solution? I know it flies in the face of good DB design, but it seems the quickest, easiest solution...
Any word if this will be fixed in the next major release of SSRS? Can we expect this release any time soon?
Thanks for looking,
Smith

I have a flat text file with lots HTML tags and corresponding valuesÂ
For exampleÂ
<Near_Side> 5563 </Near_Side>
<Top_Down_Code> Xe345 <Top_Down_Code>Â
So, For example I can use the a functionÂ
ALTER function dbo.StripHTML( @text varchar(max) ) returns varchar(max) as
begin
  declare @textXML xml
  declare @result varchar(max)
  set @textXML = REPLACE( @text, '&', '' );
[Code] ...
To which Select dbo.StripHTML('<Near_Side> 5563 </Near_Side>')  ValueÂ
I'll get 5563
However how would you get the values within the tag itself ? E.g.Â
Value NameÂ
5563 Near_side
Xe345 Â Â Â Top_Down_Code
I was thinking along the Charindex but cant seem to get it right.

I am retrieving a field from SQL and displaying that data on a web page.
The data contains a mixture of text and html codes, like this "<b>test</b>".
But rather than displaying the word test in bold, it is displaying the entire sting as text.
How do I get it to treat the HTML as HTML?

Hi,
I am getting this error: {"XML parsing: line 1, character 43, unable to switch the encoding"} System.Data.SqlClient.SqlException when I run the code below.
I know it is caused by the fact that the encoding of the XML file I'm trying to insert is not utf-16, but rather utf-8. However I would like to be able to enter any encoding. Is this possible?
If not is there a way to convert the encoding before I insert? Or any other ideas anyone might have. Thanks!
XmlDataSource xds = new XmlDataSource();
xds.DataFile = tbLink.Text.Trim();
xds.XPath = "rss/channel/item";

sqlComm.Parameters.Add(new SqlParameter("@XMLData", xmlDoc.InnerXml));

The problem is: reading data with ADO is OK (Lithuanian), but when I try to write, most of national encoding goes to hell (plain ascii). What's wrong with it? I see no option to set code page.

The following TSQL code will take a character string and perform the encoding that is necessary to generate a BARCODE 128 formatted string to be used with a BARCODE 128 font.declare @myString varchar(255)
select @myString = 'BarCode 1'
-- Define the string of characters that we'll need to pull the reference of
declare @asciiString varchar(255)
select @asciiString = ' !"#$%&''()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~'
select @asciiString = @asciiString + char(195) -- 0xC3
select @asciiString = @asciiString + char(196) -- 0xC4
select @asciiString = @asciiString + char(197) -- 0xC5
select @asciiString = @asciiString + char(198) -- 0xC6
select @asciiString = @asciiString + char(199) -- 0xC7
select @asciiString = @asciiString + char(200) -- 0xC8
select @asciiString = @asciiString + char(201) -- 0xC9
select @asciiString = @asciiString + char(202) -- 0xCA
-- Define the stop and start characters
declare @stopchar char(1)
declare @startchar char(1)
declare @spacechar char(1)
select @stopchar = char(206) -- 0xCE
select @startchar = char(204) -- 0xCC
select @spacechar = char(194) -- 0xC2
-- Define the final holding place of our output string
declare @finalArray varchar(255)
-- Define the variables that we'll need to be using
declare @checksumTotal int
declare @checksum int
select @checksumTotal = 104;
select @checksum = 0;
-- Start building our output
select @finalArray = @startchar
-- Loop through our input variable and start pulling out stuff
declare @position int
declare @thisChar char(1)
select @position = 1
while @position <= len(@myString)
begin
select @thisChar = substring(@myString, @position, 1)
select @checksumTotal = @checksumTotal + (@position * (ascii(@thischar)-32))
select @finalArray = @finalArray + @thisChar
select @position = @position + 1
end -- We've gone past the length now
-- Now we need to figure out and add the checksum character
select @checksum = @checksumTotal % 103
if @checksum = 0
select @finalArray = @finalArray + @spacechar
else
-- Barcorde array assumes 0 as initial offset so we need to add 1 to checksum
select @finalArray = @finalArray + substring(@asciiString, @checksum+1, 1)
-- Now we append the stop character
select @finalArray = @finalArray + @stopchar
-- The @final Array represents the barcode encoded string
select @finalArray
Hope it helps,
Dalton

Hi
I have a user who is using data from my database for a webportal. One of my tables had a field that was type NText. The technology he is using couldn't cope with NText so i changed the data type to nvarchar instead. The user is now getting some superfluous characters coming back as part of the data in the field e.g. '12
' where a space appears if looking at the data through something like Query Analyser. He was asking if I could change the character encoding to Unicode.
I thought that datatypes like Nvarchar were unicode anyway but I guess the fact that I changed the type might mean that I need to explicitly declare it as unicode. Does anyone know if this is the case?
thanks.

Hi!
I'm pretty new in SQL and I'm kinda confused with the concept of encoding in SQL. I tried to read several article but there are still things that I don't understand.
I have a table with two columns and these column contain english and chinese character.
CREATE TABLE Names
(FirstName NVARCHAR (50),
LastName NVARCHAR (50));
The collation for both column is Latin1_General_BIN
My question is
1. Does all data that is saved in nvarchar column have the same encoding type which is UCS-2?
2. If a client application input a chinese character into the database table, what is the encoding type of that data? Is it UCS-2?
3. If a client application successfully enter chinese characters into database table and i want to display those chinese characters saved in the database into a web page, do i need to convert those chinese character from UCS-2 (Unicode) into Big-5 encoding?
Thanks

Hi all,I have an issue on querying against UTF-16 encoded characters inSQL2000 database: For example the "López" is saved into database as"López" (due to the UTF-16 encoding); somehow, when I query datawith conditions of "like 'lop%'" or "like 'Lóp%'", the row of Lópezwould not return.NOTE: the accent insensitive collation can not help in this case.Thank you,Albion(052X)

Hi, a new (little..) problem with xml source.
I have to import large xml file in sql server and I use data transfer task and xml source.
The xml file are generated without specifing any encoding, and so I obtain many character error if i don't change the encoding.
When i put "by hand" (with a xml editor) in the xml file this encoding <?xml version="1.0" encoding="ISO8859-1"?>, the SSIS task works perfectly without any error.
So, i'm looking for a way to use this encoding without editing xml file (more than 500 mb...). the way that i can imagine are:
1) change the package encoding (but I haven't find this kind of settings)
2) change the xml source encoding (but I haven't find this kind of settings)
3) change the console chcp (normally i have 850, i have tested 1252 but without any success)
4) make a xml trasformation (but i don't know the best way); I've tried with XML task without any success...
could anybody help me?
thank you in advance

Can anyone tell me how I can strip certain chahrcters from a string
I know I can use replace, but i don't think this is appropriate for what I want to do
For example I have the string
declare @text varchar (100)
select @text = 'word1, word2 & word3'
if i do a replace on the string like this
select @text = 'replace(@text, ',', '')
select @text = 'replace(@text, '&', '')
I end up with the string
select @text = 'word1 word2 word3'
i.e. 2 spaces between word2 and word3
What i want the string to look like is :
select @text = 'word1 word2 word3'
Is there a way i can check for more than one space + characters ( / , &) in one go
many thanks

I'm storing data in SQL Server 2005 Express ntext fields. I've added <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> to the Master Page, but apostrophes and other characters are appearing incorrectly in the browser. For example, apostrophes are appearing as Æ. They seem to have changed to this when I upsized from Access to SQL Server (so I have Æ in the db field).The back-end of the site is still in classic asp, where I can set the CodePage to 65001 and the CharSet to utf-8, and everything appears fine there. What can I change in the ASPX to get characters to display correctly?

Hello,I faced a problem while reading some strings from the database (SQL 2005). Some letters are encoded with html codes making the sorting really difficult. I tried to use IComparer objects with different CultureInfo information, but it doesn't do any good.I am quite new to the web development, so I don't really have any clue if there is a recommended and clean way of solving this problem. It could be that it's something really simple, but I only came up with an idea of search and replace in all strings. If possible, I would like to omit this. :) If not, please let me know.Thanks in advance.
