I'm attempting to build a SQL job that will run the below query on a schedule as needed. However, while testing the SQL, I'm getting the following message in Query Analyzer:

quote:
(0 row(s) affected)


I have verified that there are hundreds of rows that should be updated.

The following is the Query that I'm using:

quote:

UPDATE [BUBBA_GUMP].[dbo].[Request_test]
SET finalized = '1',
Sent_for_approval = '1',
Previous_owner_ID = NULL,
Sent_from_ID = NULL

WHERE (finalized = '0'
OR sent_for_approval = '0')
AND revision_number <> '00'
AND Is_Latest = '0'



I believe that the two bolded "SET" lines are my problem, but I'm unsure as to how to correct the query.

Any help would be greatly appreciated.

Does this return something?

SELECT * from [BUBBA_GUMP].[dbo].[Request_test]
WHERE (finalized = '0'
OR sent_for_approval = '0')
AND revision_number <> '00'
AND Is_Latest = '0'

are you sure there are records satisfying below criteria?
WHERE (finalized = '0'
OR sent_for_approval = '0')
AND revision_number <> '00'
AND Is_Latest = '0'

Yes - 238 rows.

I was able to update several rows by omitting the "Previous_owner_ID = NULL" & "Sent_from_ID = NULL" lines from my SET clause, but it reverts back to "0 rows affected" when I include them.

are columns Previous_owner_ID & Sent_from_ID not nullable? what does below return?
SELECT IS_NULLABLE FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME ='Request_test' AND COLUMN_NAME IN ('Previous_owner_ID','Sent_from_ID')

[code]
select a.name 'Table', u.name 'Update Trigger'
from sysObjects a
inner join sysObjects u
on a.updtrig = u.id
where a.type != 'TR'
and a.name = 'Request_test'
[/code]

Ahhhhh, I'm an idiot.

Disregard.

I had omitted the "AND IS_Latest = '0'" from my WHERE clause, which made it appear that there were additional records that needed updating.

Thank you for your help!
