I am getting this error

Multiple-step OLE DB operation generated errors. Check each OLE DB status 

value, if available. No work was done.



It is caused by having a stored procedure with an input parameter of 

uniqueidentifer. If I change this to a varchar it doesn't happen. I can do 

this to get round the problem but I would like to know if anyone has a 

proper solution to this. From the documentation I've seen I should be able 

to use uniqueidentifer as an input parameter. I've tried doing 

microsofts 'fix' but this doesn't help.



Any ideas

Cheers

Ian
