SQL Recursive Common Table Experssion

Hi all,

I'm havnig some difficulties writing a recursive CTE to concatenate a text
field together from multiple rows.
I'm wondering if anyone can help.

I have tables ORDER_HEADER, ORDER_DETAILS, and SERIAL_MASTER.
One header can have multiple details and one detail can have multiple
serial #s.
A single order line item can have more than one machine and hence the
serial # masterfile has multiple rows with the same order# and line item#.

Example of data in SERIAL_MASTER:

Order# Line# Serial#
123456 1 ABC
123456 1 DEF
123456 1 GHI

I would like to produce the following:

Order# Line# Serial #s
123456 1 ABC: DEF: GHI

Any assistance would be greatly appreciated.


Yours truly,
