Override isolation level

When setting the transaction isolation level it could be nice to be able to control this on table level regardless of the level specified. SQL Server supports this by adding a WITH in the FROM clause.

Eg.

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE

SELECT Field FROM table t1
INNER JOIN table2 t2 WITH (READUNCOMMITTED) ON t1.ID = t2.ID

This would cause serializable locks on t1 and read uncommitted on t2.
