It's not in MSSQL Server at least through version 7 (just checked). I
don't think it has been added in MSSQL 2000 either, but I can't really
check that at the moment.

MS Access syntax is like this:

TRANSFORM Max(Table1.value) AS MaxOfvalue
SELECT Table1.name
FROM Table1
GROUP BY Table1.name
PIVOT Table1.cat;

but it *only* seems to allow TRANSFORM on an aggregate.

Syntax
TRANSFORM aggfunction
selectstatement
PIVOT pivotfield [IN (value1[, value2[, ...]])]
