mehrreihige Update Update-Trigger

Question

wie kann ich diesen Code ändern, um mit mehrreihige Update zu arbeiten. @ Id int und order_id ist Primärschlüssel, aber ich möchte jede Zeile überprüfen, die STATUS_B hat = ‚verpackt‘

select @id=inserted.order_id from inserted; 
if update(status_b) 
    begin 
    if (select status_b from inserted)='bagged' 
    begin 
     if (select o.id 
       from [order] o 
       left join [print] p on o.id=p.order_id 
       left join [laminate] l on l.order_id=o.id 
       left join [slitting] s on s.order_id=o.id 
       left join [bagging] b on b.order_id=o.id 
       where       
          1=(case when (o.printing='دارد' and status_p='printed') or o.printing='ندارد' then 1 end) 
         and 1=(case when (o.lamination='دارد' and status_l1='laminated') or o.lamination='ندارد' then 1 end) 
         and 1=(case when (o.lamination='دارد' and l.layer2<>'' and status_l2='laminated2') or o.lamination='ندارد' then 1 end) 
         and 1=(case when (o.coldseal='دارد' and status_c='coldsealed') or o.coldseal='ندارد' then 1 end) 
         and 1=(case when (o.slitting='دارد' and status_s='slitted') or o.slitting='ندارد' then 1 end) 
         and 1=(case when (o.bagging='دارد' and status_b='bagged') or o.bagging='ندارد' then 1 end) 
         and o.id=@id) is not null 
     begin 
     update [order] set [status]='finished' where id=@id 
     end 
    end 
    end 

Answer 1

sehen nicht den Zweck (Bus. Regel) Ihren Trigger in erster Linie zu verstehen.

wenn conntion mit großen Abfrage nicht erforderlich ist.Sie ​​können den gleichen Beitritt und Bedingung in direkten Update Staement binden, auf diese Weise können mehrere orderid executed und Leistung wird in Ordnung sein> diese Abfrage möglicherweise Bug, den Sie hv zu beheben Es ist aber etwas ähnliches.

UPDATE A SET [STATUS]='FINISHED' FROM [ORDER] A 
INNER JOIN INSERTED C 
ON A.ID=B.OID 
LEFT JOIN [PRINT] P ON O.ID=P.ORDER_ID 
LEFT JOIN [LAMINATE] L ON L.ORDER_ID=O.ID 
LEFT JOIN [SLITTING] S ON S.ORDER_ID=O.ID 
LEFT JOIN [BAGGING] B ON B.ORDER_ID=O.ID 
WHERE       
1=(CASE WHEN (O.PRINTING='دارد' AND STATUS_P='PRINTED') OR O.PRINTING='ندارد' THEN 1 END) 
AND 1=(CASE WHEN (O.LAMINATION='دارد' AND STATUS_L1='LAMINATED') OR O.LAMINATION='ندارد' THEN 1 END) 
AND 1=(CASE WHEN (O.LAMINATION='دارد' AND L.LAYER2<>'' AND STATUS_L2='LAMINATED2') OR O.LAMINATION='ندارد' THEN 1 END) 
AND 1=(CASE WHEN (O.COLDSEAL='دارد' AND STATUS_C='COLDSEALED') OR O.COLDSEAL='ندارد' THEN 1 END) 
AND 1=(CASE WHEN (O.SLITTING='دارد' AND STATUS_S='SLITTED') OR O.SLITTING='ندارد' THEN 1 END) 
AND 1=(CASE WHEN (O.BAGGING='دارد' AND STATUS_B='BAGGED') OR O.BAGGING='ندارد' THEN 1 END)

Probieren Sie all Auftrags-ID aus inserted nehmen und in temporärer Tabelle einfügen und tun Sie Ihre Operationen

SELECT INSERTED.ORDER_ID AS OID INTO #TEMP1 FROM INSERTED WHERE STATUS_B='bagged'; 
IF UPDATE(STATUS_B) 
    BEGIN 

     IF (SELECT O.ID 
       FROM [ORDER] O 
       join #temp1 t 
       on t.OID=o.id 
       LEFT JOIN [PRINT] P ON O.ID=P.ORDER_ID 
       LEFT JOIN [LAMINATE] L ON L.ORDER_ID=O.ID 
       LEFT JOIN [SLITTING] S ON S.ORDER_ID=O.ID 
       LEFT JOIN [BAGGING] B ON B.ORDER_ID=O.ID 

       WHERE       
          1=(CASE WHEN (O.PRINTING='دارد' AND STATUS_P='PRINTED') OR O.PRINTING='ندارد' THEN 1 END) 
         AND 1=(CASE WHEN (O.LAMINATION='دارد' AND STATUS_L1='LAMINATED') OR O.LAMINATION='ندارد' THEN 1 END) 
         AND 1=(CASE WHEN (O.LAMINATION='دارد' AND L.LAYER2<>'' AND STATUS_L2='LAMINATED2') OR O.LAMINATION='ندارد' THEN 1 END) 
         AND 1=(CASE WHEN (O.COLDSEAL='دارد' AND STATUS_C='COLDSEALED') OR O.COLDSEAL='ندارد' THEN 1 END) 
         AND 1=(CASE WHEN (O.SLITTING='دارد' AND STATUS_S='SLITTED') OR O.SLITTING='ندارد' THEN 1 END) 
         AND 1=(CASE WHEN (O.BAGGING='دارد' AND STATUS_B='BAGGED') OR O.BAGGING='ندارد' THEN 1 END) 
         ) IS NOT NULL 
     BEGIN 
     UPDATE A SET [STATUS]='FINISHED' FROM [ORDER] A JOIN #TEMP1 C ON A.ID=B.OID 
     END 
    END
