SQL - Cas Lorsque résultat dans plusieurs colonnes

Question

Salut im en utilisant cette requête de sorte que je peux fusionner la valeur dans une colonne, mais lorsque je suis en utilisant cas où il en résulte d'avoir plusieurs colonnes.

C'est ma requête

SELECT 
     SR.id, 
     CONVERT(VARCHAR(13), CAST(DR.doc_date AS DATE), 100)  as DOCDATE, 

     --FOR DOC TYPE 
     CASE 
      WHEN 
      SR.net_total IS NOT NULL THEN 'RENT TOTAL' 
     END as [DOC TYPE], 
     CASE 
      WHEN 
      SR.dell_col_charge IS NOT NULL THEN 'CHARGED' 
     END as [DOC TYPE], 
     CASE 
      WHEN 
      SR.CDW IS NOT NULL THEN 'CDW' 
     END as [DOC TYPE], 
     CASE 
      WHEN 
      SP.amount IS NOT NULL THEN 'PAYMENT' 
     END as [DOC TYPE], 
     --FOR DEBIT AND CREDIT 
     CASE WHEN 
      SR.net_total IS NOT NULL THEN SR.net_total 
      END as [DEBIT], 
     CASE WHEN 
      SR.dell_col_charge IS NOT NULL THEN SR.dell_col_charge 
      END as [DEBIT], 
     CASE WHEN 
      SR.CDW IS NOT NULL THEN SR.CDW 
      END as [CREDIT], 
     CASE WHEN 
      SP.amount IS NOT NULL THEN SP.amount 
      END as [CREDIT] 

FROM [dbo].[doc_customer] DC 
LEFT JOIN [dbo].[doc_rent] DR ON DR.doc_sourced_customer_id = DC.id 
LEFT JOIN [dbo].[slip_rent] SR ON SR.doc_sourced_doc_rent_id = DR.id 
LEFT JOIN [dbo].[slip_rent_payment] SP ON SP.doc_sourced_rent_id = DR.id 

WHERE DC.id = '1-1---1-1-1---1--1~1' 
AND DR.deleted = 0 
AND DR.void = 0 

Comme u peut le voir, je veux que mon TYPE DOC à une seule colonne même que le crédit et de débit

est-il une idée ou d'une solution à cela?

Merci

aussi ceci est mon résultat souhaité

EDIT!

ceci est mon résultat lorsque j'utilise ma requête

Answer 1

Utilisez un case unique pour chaque expression:

(CASE WHEN SR.net_total IS NOT NULL THEN 'RENT TOTAL' 
     WHEN SR.dell_col_charge IS NOT NULL THEN 'CHARGED' 
     . . . 
    END) as [DOC TYPE], 
    (CASE WHEN SR.net_total IS NOT NULL THEN SR.net_total 
     WHEN SR.dell_col_charge IS NOT NULL THEN SR.dell_col_charge 
     . . . 
    END) as [DEBIT], 
    . . . 

Cependant, cela suppose que chaque ligne ne comporte qu'un seul type de doc.

Answer 2

votre requête devrait être comme

SELECT 
     SR.id, 
     CONVERT(VARCHAR(13), CAST(DR.doc_date AS DATE), 100) as DOCDATE, 

     --FOR DOC TYPE 
     CASE 
      WHEN SR.net_total IS NOT NULL THEN 'RENT TOTAL' 
      WHEN SR.dell_col_charge IS NOT NULL THEN 'CHARGED' 
      WHEN SR.CDW IS NOT NULL THEN 'CDW' 
      WHEN SP.amount IS NOT NULL THEN 'PAYMENT' 
     END as [DOC TYPE], 
     --FOR DEBIT AND CREDIT 
     CASE 
      WHEN SR.net_total IS NOT NULL THEN SR.net_total 
      WHEN SR.dell_col_charge IS NOT NULL THEN SR.dell_col_charge 
     END as [DEBIT], 
     CASE 
      WHEN SR.CDW IS NOT NULL THEN SR.CDW 
      WHEN SP.amount IS NOT NULL THEN SP.amount 
     END as [CREDIT] 

FROM [dbo].[doc_customer] DC 
LEFT JOIN [dbo].[doc_rent] DR ON DR.doc_sourced_customer_id = DC.id 
LEFT JOIN [dbo].[slip_rent] SR ON SR.doc_sourced_doc_rent_id = DR.id 
LEFT JOIN [dbo].[slip_rent_payment] SP ON SP.doc_sourced_rent_id = DR.id 

WHERE DC.id = '1-1---1-1-1---1--1~1' 
AND DR.deleted = 0 
AND DR.void = 0 

Answer 3

En utilisant une expression case avec plusieurs cas, et coalesce() de prendre la première colonne non null pour debit et credit

select 
    sr.id 
    , convert(varchar(13), cast(dr.doc_date as date), 100) as docdate 
    --for doc type 
    , case 
     when sr.net_total is not null then 'rent total' 
     when sr.dell_col_charge is not null then 'charged' 
     when sr.cdw is not null then 'cdw' 
     when sp.amount is not null then 'payment' 
    end as [doc type] 
    --for debit and credit 
    , coalesce(sr.net_total,sr.dell_col_charge) as [debit] 
    , coalesce(sr.cdw,sp.amount) as [credit] 
from [dbo].[doc_customer] dc 
    left join [dbo].[doc_rent] dr 
    on dr.doc_sourced_customer_id = dc.id 
    left join [dbo].[slip_rent] sr 
    on sr.doc_sourced_doc_rent_id = dr.id 
    left join [dbo].[slip_rent_payment] sp 
    on sp.doc_sourced_rent_id = dr.id 
where dc.id = '1-1---1-1-1---1--1~1' 
    and dr.deleted = 0 
    and dr.void = 0
