Have a user who needs to edit a link and says he cannot edit it because it is owned by a different user?  I think we may have run across this years ago but not sure.  If it is true he cannot edit the link then we need to fix this.  The person who owns most of the links has left the company and we probably need to change them all to the person who will be making the edits for now.  
 
Is this a global field replace?  on the UID in the ISLINKS table?
 
Kind regards,

Have you try this?
 
update ISLINKS SET IS_LNK_WHO='YOUR DBA USER ID' where length(LTRIM(RTRIM(IS_LNK_WHO)))<>0;

PD: before running any sql script always backup your table .......

When you look at the links there is a box that says View. That is to make the link as view only so only that user or a ADMIN can change it. So if its unchecked then any user who has access should be able to edit that link.
