I'm trying to figure out why an update statement is failing to update.
If I do a SELECT I get the following
select locn.locnnbr,lav.AttribCd, locn.OccupancyCountBedYN , v.Descript
from locn
JOIN dbo.LocnAttribVal lav on lav.LocnNbr = locn.LocnNbr
JOIN AttribVal v on v.AttribValNbr = lav.AttribValNbr
where lav.AttribCd = 'BDCB'
locnnbrAttribCdOccupancyCountBedYNDescript
960 BDCB N Y
961 BDCB N Y
962 BDCB N Y
963 BDCB N Y
964 BDCB N Y
There are over 9500 rows. This is a sample of the data
The UPDATE looks like
UPDATE l
SET OccupancyCountBedYN = v.Descript
from locn l
JOIN dbo.LocnAttribVal lav on lav.LocnNbr = l.LocnNbr
JOIN AttribVal v on v.AttribValNbr = lav.AttribValNbr
where lav.AttribCd = 'BDCB'
So this OccupancyCountBedYN should be 'Y' after the update
I get the following when I execute the update
(9547 row(s) affected)
But yet all my rows are still 'N'
Any ideas?

There's a Begin Tran and Rollback in the code somewhere.

Without explicitly trying the code, no ddl to work with, it looks like it should work.

There might also be a hidden update trigger on the table affecting the results?

You wouldn't believe how often folks have been caught out by omitting a seemingly inocuous bit of code from a query, only to find it's the part which is causing the problem. Can you post the whole statement please?

It turned out to be a hidden trigger that wasn't disabled during the upgrade process.
