Hi all,
recently I started working with SQLServer 2005 and found a new Isolation Level named Snapshot or database versioning. This has some advantages.
Oracle has it too.
Does db2 or maybe db2v9 have some similar isolation ?
Not so far, but I agree it needs it. At the moment, the isolation levels are:-
1. Repeatable read (locks every row read in the cursor)
2. Read Stability (locks every row selected in the cursor)
3. Cursor Stability (locks the current row selected in the cursor)
4. Uncommitted Read (Doesn't lock any rows and reads uncommitted data).
