Hi folks.... Might sound like a silly question, but I'm looking for some SQL statements (the more basic the better) in 10gR2 that will cause an ORA-0600 error. If you have one and an associated test case that you could sent that would be great. You can send to me direct mail rather than through the newsgroup, robertgfreeman@xxxxxxxxxx RF Robert G.
