Hi all I need a little help on a problem I have. My client has a sql db that is populated by (muppets) they have a free txt field that is set to varchar(8000) and they should type in there what they have fixed for the person calling but they don't they type in word and copy and paste so we are left with a load of strange characters to remove. I have been able to remove all from the body of the txt but have a problem with the leading txt. My issue is there is two points it can start from and I need to do this in one code any help would be grateful.


#2

It would help if you would post a snippet or example of your input data and along with what it should look like once corrected


#3

I'd love to but the data is sensitive


#4

You can obfuscate the data and post that, or just make up your own bogus sample data that is representative of the problem that you want to solve.

I read your posting couple of times, but still was not able to follow the issue you are trying to resolve.


#6

I have removed all personal details but it will not allow me to upload the code as it mentions two or more names I will try and upload it separate.

The issue I have is with the charindex

SUBSTRING([CUST_SiteVisitDetails],
CHARINDEX(';}',[CUST_SiteVisitDetails]), LEN([CUST_SiteVisitDetails])), ';}', '')

It is looking for ;} in Cust_SiteVisitDetails and when I change it to 'From:{\f322\cf0 ' from CUSTSiteVisitDetails that works but the data that is in the Variable table is normally one column. so I need both to work in one SUBSTRING

RTF is a nightmare ... you can't just strip out the stuff between { and } because sometimes it contains embedded characters, not just formatting - its optimised to include text within the {xxx} to save having multiple sets of {\formatting} tags.

Here is a thread that has a go at removing RTF

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=90034

I would put a trigger on the table and rollback any attempt to store what looks like RTF in the record. That will take care of future data (presumably the user's browser has a Paste-as-plain-text option, if not there are Browser TextBox controls that let you do that (and, I think, can preserve formatting in a way that HTML can view them, if you actually want that)
