Reading Null values/Empty Strings in Excel sheet using Oracle forms
When reading an empty cell from an excel sheet using ole2, I use 'IS NULL' and it works.
But when I do the same on a server client architecture i.e. using client_ole2, it doesn't work and I have to change it to " = 'null' ". Otherwise it throws a non-oracle exception or goes into an infinite loop.
Why is it so? Is it documented in oracle's documentation anywhere?
