connect by in ms-sql server

Hi,

I have the following oracle select stmt:-
--------------------------------------------------------
select tax_region_cd from ref_tax_region
start with tax_region_cd = 'VC_CITY1'
connect by prior parent_tax_region_cd = tax_region_cd
--------------------------------------------------------

How can i convert it into ms-sql server script? Do we have connect by clause in ms-sql? If not then what can be the work around?

thanking you,

Parijat Paul

There is a work around:

The difficult part of the design is assigning left number and right number, and maintaining the hierarchy. The left and right numbers of each node contain the left and right numbers of the ancestors of that node. For assigning the left and right numbers, use a procedure/function.
