sql server programming:

I need to run this update

Update
Cases
set archived = 2

But only on records found with this query ...

Select * from
Cases
Inner join processstep
ON cases.PROCESSSTEP = processstep.ProcessstepID
where processstep.Processtep LIKE '%closed%'

How can I do this ?

Hi,

This is one method:-

Update Cases
set archived = 2
where PROCESSSTEP in (select ProcessstepID from processstep where Processtep
LIKE '%closed%')

Thanks

UPDATE Cases
SET archived = 2
WHERE EXISTS
(SELECT *
FROM ProcessStep
WHERE processstepid = Cases.processstep
AND processstep LIKE ' %closed%')

A good naming convention is to use the same name whenever an attribute
appears in more than one table. On this basis you would presumably have used
the name "processstepid" for the column in Cases to avoid confusion with the
column "processstep" in the ProcessStep table, which apparently is a
different attribute altogether in this case.
