Hướng dẫn sql remove html tags

It is doable without the creation of a Table-Valued Function but is NOT pretty

Cross Apply B will "Clean the String" this may require some maintenance.

Cross Apply C will Split/Parse the String, reduce it down to values between > ... < and then aggregate the string.

You may notice that char(13) and char(10) are NOT removed, but replaced with a space. This is to ensure the replace is not destructive.

Example

Declare @YourTable table (ID int, [Message] varchar(max))
Insert Into @YourTable values
 (1,'
test
George C Test2 


')
,(2,'
This is the Title
The content
Extra       Spaces will be trapped.  The End
')
,(3,'No HTML Tags')

Select A.id
      ,NewValue = ltrim(rtrim(replace(replace(replace(TxtOnly,' ','†‡'),'‡†',''),'†‡',' ')))
 From  @YourTable A
 Cross Apply ( values ( replace(
                        replace(
                        replace(''+[Message]+''
                        ,char(13),' ')
                        ,char(10),' ') 
                        ,' ',' ')   -- May want to add items like — as -  and ™ as TM etc...
                      ) 
              ) B(CleanString)
 Cross Apply (
                Select TxtOnly = stuff((Select ' ' +RetVal 
                                         From  (
                                                Select RetSeq

                                                 From  (

                                                        From  ( values (cast('' + replace((Select replace(CleanString,'>','§§Split§§') as [*] For XML Path('')),'§§Split§§','')+'' as xml).query('.'))) as A(x)
                                                        Cross Apply x.nodes('x') AS B(i)
                                                       ) C1
                                                Where charindex('<',RetVal)>1
