In other words, is the following "cursoring" approach guaranteed to work:
- retrieve rows from DB
- save the largest ID from the returned records for later, e.g. in
LastMax - later,
"SELECT * FROM MyTable WHERE Id > {0}", LastMax
In order for that to work, I have to be sure that every row I didn't get in step 1 has an Id greater than LastMax. Is this guaranteed, or can I run into weird race conditions?
