RANK/GROUP Ergebnis nach der Bestellung

Question

Ich habe SQL-Abfrage, die ich versuche, das Ergebnis RANG/GROUP angezeigt, nachdem es bestellt wurde.

Dies ist für einen Fall (UNIQSN), die von einem Speicherort (SLOC) zu einem anderen wechselt. Ich versuche chronologisch die Geschichte ihrer Reise zwischen Lagerorten zu erfassen.

"Code" ist mehr als tausend Worte wert!

habe ich versucht, die Abfrage unter:

SELECT 
    uniqsn, 
    SLOC, 
    Update_DATETIME, 
    RANK() OVER (PARTITION BY SLOC ORDER BY Update_DATETIME) RANKING 
FROM TABLE 

I

Get

Answer 1

Sie haben ein Lücken- und Inseln-Problem. Außerdem möchten Sie die Gruppen bis zum frühesten Datum (von dem, was ich sagen kann) bestellen.

Zu diesem Zweck:

select t.*, dense_rank() over (partition by uniqsqn order by min_ud) as ranking    
from (select t.*, 
      min(update_datetime) over (partition by uniqsqn, sloc, seqnum - seqnum_us) as min_ud 
     from (select t.*, 
        row_number() over (partition by unisqn order by update_datetime) as seqnum, 
        row_number() over (partition by uniqsqn, sloc order by update_datetime) as seqnum_us 
      from t 
      ) t 
    ) t;
