I think this definitely qualifies as a 'technical' topic and not a
'nontechnical' topic.
I am not nit picking. There are a lot of good technical people on the
technical list who simply do not have the time nor desire for some of the
stuff on the 'nontechnical' list.

Sorry if this has been asked before -- I am new to this list. Are

Common Table Expressions (CTE) not supported for UPDATE statements? Since

I am getting Message: [SQL0199] Keyword UPDATE not expected. Valid tokens:

( SELECT VALUES. this leads to me to this conclusion -- unfortunately.
Tell me it ain't so.

With SequList (WaitId, ItemName, ItemType, ItemAttr, WaitSequ)
as (Select UTWAITLT_ID, Item_Name, Item_Type, Item_Attribute,
Wait_Sequence
From Waiting_List
Where Item_Name = 'UTWAITBRSM'
And Item_Type = '*MODULE'
And Item_Attribute = 'SQLRPM'
Order by Item_Name, Item_Type, Item_Attribute, Wait_Sequence
)
Update SequList as cte
Set cte.WaitSequ = NEXT VALUE FOR TEMP_SEQ
Where cte.WaitId IN (Select WaitId from SequList)
Order by Item_Name, Item_Type, Item_Attribute, Wait_Sequence;

Basically, what I am trying to accomplish is to resequence, in
place, a numeric column from 10 by 10. This is used in a priority list
where an entry's priority can change. Thus, for example, if there are 5
entries in a particular group and the entry at priority 30 is changed to
priority 5, I then want to resequence that group of entries from 10 such
that the changed entry will remain with the highest priority of 10 --
i.e., raising it from 30 to 10 -- and moving all other entries in the
group down by 10 for each existing entry. I've been able to resequence
the column but I have not been able to resequence according to the new
priority sequence -- rather, it resequences by the primary identity key no

matter what I try. How can I accomplish this?

Sincerely,

Dave Clark
