did you tried it
Mark the answer as accepted if that worked for you  .
And for down-voters please specify the reason to improve the solution .

Yes I did, but there is no way I can cast decimal to float.
I did a work around but it is ugly, it could cause a performance issue, so I am still looking for a better solution.

Soooo... what's the definition of the column?
Where's the code you're using?

I am trying to replace names found in 'xml' fieldname as hyperlinks, by matching with the names in database_tags.
I am using the following function below, however the UDF is only recognizing one name from the XML fieldname data, instead of all the names present in the XML data.
ALTER FUNCTION [dbo].[ReplaceTags](@XML VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE @N VARCHAR(MAX)
SELECT @N = [Name] FROM [dbo].[database_tags]
WHERE @XML LIKE '%'+[Name]+'%'
AND UploadDate >= '2014-09-01'
IF @N IS NOT NULL
BEGIN
SELECT @XML = REPLACE(@XML,
@N,
'<a href="<a href="pagename.aspx?tag='+@N+'">'+@N+'</a>')
END
RETURN @XML
END
for example, if the XML input data is the following: It consists of: BANKP, BCJA, BCJAM, BFTH, BFTH, and EMPOP.
But the updated function is only recognizing two of names BFTH, BFTH, as hyperlinks, from the database_tags table.
Is there a way to get the function to recognize more than one names as hyperlinks.
Thank you very much for your time and help.

Try this:
ALTER FUNCTION [dbo].[ReplaceTags]( @XML VARCHAR(MAX) )
RETURNS VARCHAR(MAX)
AS
BEGIN
SELECT
@XML = Replace(@XML, [Name], '<a href="pagename.aspx?tag=' + [Name] + '>' + [Name] + '</a>')
FROM
[dbo].[database_tags]
WHERE
@XML LIKE '%' + [Name] + '%'
And
UploadDate >= '2014-09-01'
;
RETURN @XML;
END
GO

Thank you very much for your reply and help.
I have already tried the above approach and unfortunately, it gives me incorrect output.
I pass the following XML Input to the UDF:
<Body><p align="justify">One is a 1m block of AIREM 2006-1X 2A3, which has never appeared on SMO.<p></Body>
the function above, outputs the following (which is incorrect).
One is a £1m block of <a href="<a href="pagename.aspx?tag=<a href="<a href="pagename.aspx?tag=<a href="<a href="pagename.aspx?tag=<a href="<a href="pagename.aspx?tag=<a href="<a href="pagename.aspx?tag=AIREM 2006-1X 2A3">AIREM 2006-1X 2A3</a>"><a href="<a href="pagename.aspx?tag=AIREM 2006-1X 2A3">AIREM 2006-1X 2A3</a></a>"><a href="<a href="pagename.aspx?tag=<a href="<a href="pagename.aspx?tag=AIREM 2006-1X 2A3">AIREM 2006-1X 2A3</a>"><a href="<a href="pagename.aspx?tag=AIREM 2006-1X 2A3">AIREM 2006-1X 2A3</a>
The desired output should be :
<Body><p align="justify">One is a 1m block of <a href="pagename.aspx?tag=AIREM 2006-1X 2A3">AIREM 2006-1X 2A3</a>, which has never appeared on SMO.<p></Body>
I have attached an example of my dataset in the following link below, for further reference as to what my dataset types are.
http://sqlfiddle.com/#!6/96cac8/2
I looked into a cursor approach for this replace function and have come up with the following below. However, I am still experiencing the same output error, as explained above. the function loops through continuously and creates duplicate names of hyperlinks, within the XML data.
ALTER FUNCTION [dbo].[ReplaceTags2](@XML VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE @Name VARCHAR(MAX)
DECLARE CUR CURSOR FAST_FORWARD FOR
SELECT name
FROM [dbo].[database_tags]
Where UploadDate >= '2014-09-01'
and @XML LIKE '%' + Name + '%'
OPEN CUR
WHILE 1 = 1
BEGIN
FETCH cur INTO @name
IF @@fetch_status <> 0
BREAK
BEGIN
SELECT @XML = REPLACE(@XML,
@Name,
'<a href="<a href="pagename.aspx?tag='+@Name+'">'+@Name+'</a>')
END
END
CLOSE CUR;
DEALLOCATE CUR;
RETURN @XML
END
Please advice further, if possible.
Thank you for your help and time.

I can't reproduce the problem using your SQL Fiddle data and the code I posted.
<Body><p align="justify">One is a 1m block of <a href="pagename.aspx?tag=AIREM 2006-1X 2A3>AIREM 2006-1X 2A3</a>, which has never appeared on SMO.<p></Body>
<body>It consists of: <a href="pagename.aspx?tag=BANKP>BANKP</a>, <a href="pagename.aspx?tag=BCJA>BCJA</a>, <a href="pagename.aspx?tag=BCJA>BCJA</a>M, <a href="pagename.aspx?tag=<a href="pagename.aspx?tag=BFTH>BFTH</a>><a href="pagename.aspx?tag=BFTH>BFTH</a></a>, <a href="pagename.aspx?tag=<a href="pagename.aspx?tag=BFTH>BFTH</a>><a href="pagename.aspx?tag=BFTH>BFTH</a></a>, and <a href="pagename.aspx?tag=EMPOP>EMPOP</a>.</body>
DECLARE @XML nvarchar(max);
SELECT
@XML = XML
FROM
article
WHERE
id = '1'
;
SELECT
@XML = Replace(@XML, [Name], N'<a href="pagename.aspx?tag=' + [Name] + N'>' + [Name] + N'</a>')
FROM
[dbo].[database_tags]
WHERE
@XML LIKE N'%' + [Name] + N'%'
;
SELECT @XML As Result;
NB: You should avoid using text, ntext or image types in SQL. They are deprecated and will be removed in a future version[^]. Use varchar(max), nvarchar(max) and varbinary(max) instead.

Please note that I've repeated Richard's solution and don't get any problem either. I know that it's frustrating!
Can we see the code you are using to call the UDF?

Thank you for your suggestion and help.
I am manage to get the cursor function work by adding a distinct clause in the tags select query of function:
DECLARE @fullame VARCHAR(MAX)
DECLARE CUR CURSOR FAST_FORWARD FOR
SELECT distinct name
FROM database_tags
Where UploadDate >= '2014-09-01'
Thank you very much Richard for your solution, I am sorry to inform, the above solution was little slow loading the articles with hyperlinks name, hence I choose the cursor function approach.
Thank you all, for your time and suggestion for this post. I appreciate all your help.

You are welcome! Richard's solution should have worked - that is the one I also tested and is exactly the approach I would have used. I only mentioned the cursor to help you understand the problem, but if it works ...!
If Richard's query is performing badly, it could probably be improved with a well-chosen additional index. When you have some time, I'd suggest running it with the SQL query analyzer.
Good luck!

Your problem is caused by the fact that only one name match will work. Although your first select statement will potentially return multiple rows @N will only ever have one value. Using Richard's method you are wrapping everything in together. Your approach would have required being wrapped in a cursor to enumerate your first select.

Hi,
I am trying to save an html text which is less than 1MB using LONGTEXT datatype but getting:

sorry, forgot to mention it..
It's MySQL

Are you sure the error relates to your LONGTEXT column? Assuming this is MySQL, the column should be able to store up to 4,294,967,295 characters.

How are you saving an image in an HTML string - embedded as a data URI, or something else?
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

|

base64 string like this:
<img src="data:image/png;base64,.........
Technology News @ www.JassimRahma.com
|
|
|
|
|
OK, that shouldn't significantly increase the size. The Base64 encoded string shouldn't be more than 1/3 larger than the raw bytes.
So param_message is definitely the parameter you're using to pass the HTML?
Can you post the code you're using to create the command object and its parameters?
