How can I restore a field back to Null?

Hello,
I need to restore fields for records meeting a certain criteria back to
null. Is there a way to do this in a stored procedure?
dbuchananI figured it out.
\\
Update tbl040cmpt SET
cmSmallint08 = cmSmallint05,
cmSmallint04 = null
FROM tbl040cmpt
WHERE fkJob = 'd8779793-5f1a-4092-bad3-bf3ee5b50c3e'
