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 (as shown in the example below). How can I accomplish
this?
Alter Sequence TEMP_SEQ Restart with 10;
Update Turnover_Waiting_List
Set Wait_Sequence = NEXT VALUE FOR TEMP_SEQ
Where TOWAITLT_ID IN (Select TOWAITLT_ID
From Turnover_Waiting_List
Where Item_Name = 'TOWAITBRSM'
And Item_Type = '*MODULE'
And Item_Attribute = 'SQLRPM'
Order by Item_Name, Item_Type, Item_Attribute,
Wait_Sequence)
With NC;
Sincerely,
Dave Clark
