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.

Subject: Common Table Expressions with UPDATE
Sent by: "Midrange-NonTech" <midrange-nontech-bounces@xxxxxxxxxxxx>
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
