Convert RTF to varchar in SQL Server

问题

I am trying to convert a varbinary to varchar but it is causing some unwanted characters to show up, as shown below. Could someone please let me know if there is any best way to do it.

I'm trying the following query

SELECT
    BLOB_CONTENTS, 
    CONVERT(VARCHAR(MAX), [BLOB_CONTENTS]), 
    CONVERT(NVARCHAR(MAX), [BLOB_CONTENTS]) 
FROM 
    [hie_temp].[V500].[CE_BLOB] 
WHERE
    EVENT_ID = '760365' 

varbinary code like this :

0x05028A64F2A9488645100E84053281148A4324080A0412A1209E4C2791CB2208EC7A3F2090C7

I am getting something like this

回答1:

RTF is not plain text, you need to write a procedure/function to convert RTF to text, see here.

Alternatively you can do it in your programming language, see this post for an example in C#.
