SQL ALTER TABLE Question

Hi,

I'm fine changing the field type on a single field using the following sql:

ALTER TABLE #TP#_TemporaryTable
ALTER COLUMN Price double

I need to change multiple field types, can this be done in a single sql statement. I've tried

ALTER TABLE #TP#_TemporaryTable
ALTER COLUMN Price double
ALTER COLUMN UPC double

and a few others, but no luck. Is it possible to do this?

Thanks!
