What is the Optional(other than Case or Decode)

Question

Hi friends,
i need to refer an image to the corresponding blob content in my report for each and every row. i tried with case or decode but it is helpless as the case and decode does not support BLOB format, instead what is the other optional i can use inorder to solve the problem
SELECT
  decode(attachment,(select attachment from it_issues where lower(name) like '%txt%') ,
       '<img src="#WORKSPACE_IMAGES#Notepad.jpg">',
       (select attachment from it_issues where lower(name) like '%pdf%'),
       '<img src="#WORKSPACE_IMAGES#Adobe pdf.bmp">',
        (select attachment from it_issues where  lower(name) like '%xls%'),
       '<img src="#WORKSPACE_IMAGES#Excel.png">',
        (select attachment from it_issues where  lower(name) like '%html%'),
       '<img src="#WORKSPACE_IMAGES#Html.bmp">',
        (select attachment from it_issues where  lower(name) like '%sql%'),
       '<img src="#WORKSPACE_IMAGES#Notepad.jpg">',
        (select attachment from it_issues where  lower(name) like '%ppt%'),
       '<img src="#WORKSPACE_IMAGES#powerpoint.jpg">',
        (select attachment from it_issues where  lower(name) like '%zip%'),
       '<img src="#WORKSPACE_IMAGES#rar 02.bmp">',
        (select attachment from it_issues where  lower(name) like '%doc%'),
       '<img src="#WORKSPACE_IMAGES#word.bmp">', null) Attachment
  FROM   it_issuesAbove is My code which is not sufficient to use, any replacement to it.. It will be very helpful for me

Hi metzguar,
Thanks for the reply my image is stored in the attachment column but that image name is stored in filename column in my table, so i cannot refer attachment = txt, because the image name(txt)is stored in another column filename.
But i need to show the image icon in my attachment column where the image is storing. That is the problem for me.
Thanks
