SQL PIVOT With Dynamic List...

I've the following pivot statement...

SELECT PartType, PartTypeSize, [000], [050], [075], [100]
FROM (SELECT     PartType, PartTypeSize, Op_Num, SerialNumber FROM vWIP) AS S
PIVOT (Count(SerialNumber) FOR Op_Num IN ([000], [050], [075], [100]) AS D

The values for [000], [050], [075], [100] are pretty crude.  But it works for this example.  Is there a way to dynamically build these values based upon a select statement.  More like...

SELECT PartType, PartTypeSize, (SELECT DISTINCT values FROM table WHERE condition)
FROM (SELECT     PartType, PartTypeSize, Op_Num, SerialNumber FROM vWIP) AS S
PIVOT (Count(SerialNumber) FOR Op_Num IN (SELECT DISTINCT values FROM TABLE WHERE condition) AS D

I figured that I can do this in software and dynamically build the statement. but currently I've this defined in a database view and would like the values to be based upon a changing table.

Possible?  probably not...  Asking for too much probably

You can do it in SQL in the same way you would in software using dynamic SQL statement.  You would query and build a string representing your SQL statement with hardcoded column names (except you didn't have to hand type them) and you execute like this:

EXEC(@dynamicSQL)
