I have a massive table (company, plant, resource, part number) that I need to create a from part number, to part number for every part within "Company, Plant, Resource" combo.Trying to figure out what the best method would be.. using a cursor will put the load on one CPU and take way too long.
Ideas?
SELECT company, plant, resource, MIN(partno) as [from part number], MAX(part number) as [to part number]
FROM table
GROUP BY company, plant, resource
