I have a textfield SectionText in column in my table Section. The sectionText field contains multiple instances of html
with font references. e.g.
 <div>Below is a list of industry regulators that need to be notified when an incident occurs. The regulators may make arrangements to visit the site to assess any potential problems in the short, medium and long term. 
I want to write an update statement that replaces all occurrences of font-family: with "font-family: Arial;" i.e. all the html has the same arial font.
I thought I could use the REPLACE function
select replace(SectionText, '%"font-family:%;"%', '"font-family: Arial;"')
from tSection
But you can’t use wildcard characters.
I found the below bit of code on the web, which does work, but it only replaces the first occurrence of the word “font-family”, there could be multiple instances in the same field.
select
SUBSTRING(SectionText,1,CHARINDEX('"font-family:',SectionText))
+ '"font-family: Arial'+
SUBSTRING(SectionText,CHARINDEX(';"',SectionText,CHARINDEX('"font-family:',SectionText)),
LEN(SectionText)
)
from tSection
where SectionText like '%"font-family:%;"%'
If you can help that would be great!

Your best friend here will be CLR function with RegEx.Replace.

You will need to develop this function in .NET (c# or vb.net).

If you don't know any of .NET language, you will need help from .net developer

Extract the data, send it to a web developer, get them to change it, import it back in ?

here's a TSQL method, which generates the actual REPLACE statements you would want to use to remove the css style assignment, if it exists.

Notice how i'm generating a lsit of "DesiredString", which is found within the data, and then use that as the basis for creating a suite of REPLACE commands:

--Results:
UPDATE #Inventory_Trans SET Description = REPLACE(Description,'font-family: Arial;','')
UPDATE #Inventory_Trans SET Description = REPLACE(Description,'font-family: Courier New ;','')
UPDATE #Inventory_Trans SET Description = REPLACE(Description,'font-family: Times Roman;','')
UPDATE #Inventory_Trans SET Description = REPLACE(Description,'font-family: Verdana;','')

Create table #Inventory_Trans (OtherId int,Description varchar(max) )

insert into #Inventory_Trans

SELECT 1,' <div>Below is a list of industry regulators that need to be notified when an incident occurs. The regulators may make arrangements to visit the site to assess any potential problems in the short, medium and long term. '

UNION ALL

SELECT 2,' <div>Below is a list of industry regulators that need to be notified when an incident occurs. The regulators may make arrangements to visit the site to assess any potential problems in the short, medium and long term. <div>Below is a list of industry regulators that need to be notified when an incident occurs. The regulators may make arrangements to visit the site to assess any potential problems in the short, medium and long term. '

--now get the ID's using a tally table

declare

@pre varchar(100),

@post varchar(100),

@pr int,

@po int,

@st int

set @pre = 'font-family:'

set @post = ';'

set @pr = len(@pre)

set @po = len(@post)

set @st = 1

;WITH tally (N) as

(SELECT TOP 10000 row_number() OVER (ORDER BY sc1.id)

FROM Master.dbo.SysColumns sc1

CROSS JOIN Master.dbo.SysColumns sc2)

SELECT top 30

T1.N,

T2.*,

@pre +

SUBSTRING( T2.Description,

( CASE T1.N WHEN 1 THEN 1 ELSE T1.N + @pr END ),

( CASE CHARINDEX( @post, T2.Description, T1.N + @pr ) WHEN 0 THEN LEN( T2.Description ) - T1.N + @pr

ELSE CHARINDEX( @post, T2.Description, T1.N + @pr ) - ( T1.N + @pr ) END ) )

+ @post AS DesiredString,

Description as Description2

Into #Results --capture into an intemediary table

FROM Tally T1

CROSS APPLY #Inventory_Trans T2

WHERE N <= LEN( T2.Description )

AND SUBSTRING( T2.Description, T1.N, @pr ) = @pre

SELECT * from #Results

select distinct 'UPDATE #Inventory_Trans SET Description = REPLACE(Description,''' + DesiredString + ''','''') '

from #Results

drop table #Inventory_Trans

drop table #Results
