Andy,

WITH Specifies the isolation level at which the statement is executed. (Isolation level does not apply to declared temporary tables because no locks are acquired.) You can have the following values.

Code:

RR  Repeatable read
RS  Read stability
CS  Cursor stability
UR  Uncommitted read


WITH UR can be specified only if the result table is read-only.


Check this link which explains in detail

Hope this helps...

Cheers
