Yes, it is possible by using in memory table variables on
SQL server 2000 and above.
A table variable can be created and all disticnt values can
be inserted into this table and then deleting all rows from
first table you can insert back disticnt rows to back to
original table. Table variable would automatically be
destroyed whenever bacth execution finishes.
