hi all,

i'm wondering whether the access of xmltype column data has any concurrency locking mechanism like ATOM? mostly i'm worried is the Isolation part upon reading the xml type data.

eg. if reading, update,deleting particular node on xml, is there any locking pattern like READ COMMITED, SERIALIZED etc. accessing this information would be in stored programs only so it's constraint to PL/SQL environment.

anyone has details on this and please advise and educate me, thanks

for oracle, it's just another column, even if the underlying structure is object relational,  the "main" table has a single column in a single row.  All locking/isolation issues are handled at that layer.
