Hi all,

When I try to compare Blob in a Trigger, this error occurs:

if( old.Obs != new.Obs ) then...


SQL Message : -901
Unsuccessful execution caused by system error that does not preclude
successful execution of subsequent statements

Engine Code : 335544382
Engine Message :
BLOB not found


Im using Firebird 2.1

Is there a way to do that ? or a better way ?

thanks any help
