SQL unir 2 consultas que comparten una columna

Question

Tengo 2 consultas SQL que comparten una columna llamada catalogid

Consulta #1:

Select 
   catalogid, numitems, allitems - numitems ignoreditems
from
    (select 
        i.catalogid,
 sum(case when (ocardtype in ('PayPal','Sofort') OR
                ocardtype in ('mastercard','visa') and
                odate is not null) then numitems
                else 0 end) numitems,
 sum(numitems) allitems
from orders o"
join oitems i on i.orderid=o.orderid"
join products T1 on T1.catalogid = i.catalogid"
group by i.catalogid) X 

Consulta #2:

SELECT catalogId, ProcessedSucssessfully =
       STUFF((SELECT ', ' + CAST( b.orderid as varchar(10))
              FROM oitems b JOIN orders o ON b.orderid = o.orderid
              WHERE b.catalogId = a.catalogId
              AND (o.ocardtype in ('PayPal','Sofort') OR o.ocardtype in  ('mastercard','visa') and o.odate is not null)
              FOR XML PATH('')), 1, 2, ''),
                  NotProcessed =
        STUFF((SELECT ', ' + CAST( c.orderid as varchar(10))
               FROM oitems c JOIN orders o ON c.orderId = o.orderid
               WHERE c.catalogid = a.catalogid
               AND (o.ocardtype in ('mastercard') OR o.ocardtype is null) and o.odate is null
               FOR XML PATH('')), 1, 2, '')
FROM oitems a
GROUP BY a.CatalogId

¿Cómo le hacen los 2 en una consulta o unirse a ellos?

Nota I ejecutar los 2 como SqlCommand de vb.net

Una cosa a notar es que tengo el mismo tanto para las consultas, lo que he intentado hacer es agregar la segunda consulta de las partes a seleccionar el caso de que no funcionara

Aquí están las tablas implicadas

oitems tabla

Las condiciones para la Consulta1:

1. si ocardtype es vacío, entonces ignorar la numitems y la consideran como 0 en la suma y suma la omisión de elementos para la ignoreditems columna

2. si ocardtype para algunos el fin es MasterCard o Visa y el odate es vacío, entonces ignorar la numitems y se considera como 0 y suma la omisión de elementos para la ignoreditems columna

3. si ocardtype es a través de Paypal o Sofort, a continuación, sólo hacer el numitems suma sin la comprobación de la fecha porque esos tipos no requieren odate

Las condiciones para Query2 que son los mismos Que Consulta1 pero diferentes cosas para hacer:

1. si ocardtype está vacía, a continuación, agregue orderid a NotProcessed

2. si ocardtype para algunos el fin es MasterCard o Visa y el odate está vacía, a continuación, agregue orderid a NotProcessed

3. si ocardtype es a través de Paypal o Sofort, entonces no busque odate y añadir el orderid a ProcessedSucssessfully

El de arriba se hacen las cosas en separados 2 consultas, pero estoy tratando de hacer una consulta ya que tienen las mismas condiciones

Answer 1

Ok aquí vamos, he construido la estructura de la tabla para validar el SQL.Yo no cargar los datos pero no ejecutar.

SELECT * FROM
(
Select  
   catalogid, numitems, allitems - numitems ignoreditems 
from 
    (
        select  
            i.catalogid, 
            case 
                when ocardtype in ('PayPal','Sofort') then sum(i.numitems)
                when ocardtype in ('mastercard','visa') and odate is not null then sum(i.numitems)
            else 0 end numitems, 
            sum(numitems) allitems 
        from 
            orders o
        inner join
            oitems i 
        on 
            i.orderid=o.orderid
        inner join 
            products T1 
        on 
            T1.catalogid = i.catalogid
        group by 
            i.catalogid, ocardtype, odate
    ) A
) B
INNER JOIN
(
    SELECT 
        catalogId, 
        ProcessedSucssessfully = 
           STUFF((SELECT ', ' + CAST( b.orderid as varchar(10)) 
                  FROM oitems b JOIN orders o ON b.orderid = o.orderid 
                  WHERE b.catalogId = a.catalogId 
                  AND (o.ocardtype in ('PayPal','Sofort') OR o.ocardtype in  ('mastercard','visa') and o.odate is not null) 
                  FOR XML PATH('')), 1, 2, ''), 
                      NotProcessed = 
            STUFF((SELECT ', ' + CAST( c.orderid as varchar(10)) 
                   FROM oitems c JOIN orders o ON c.orderId = o.orderid 
                   WHERE c.catalogid = a.catalogid 
                   AND (o.ocardtype in ('mastercard') OR o.ocardtype is null) and o.odate is null 
                   FOR XML PATH('')), 1, 2, '') 
    FROM 
        oitems a 
    GROUP BY 
        a.CatalogId 
)C
    ON 
        B.CatalogId = C.CatalogId

Answer 2

Puede crear una vista en sql cuadro y, a continuación, sólo Linq to que ver

select * from table_a inner join table_b on table_a.field_a = table_b.field_b

EDITAR:

o

Select * from (select * from table_a inner join table_b on table_a.field_a = table_b.field_b) AB
inner join
select * from (select * from table_c inner join table_d on table_c.field_c = table_d.field_d) CD
ON
AB.id_column = CD.id_column

Answer 3

Vista de SQL server sería algo como esto

SELECT * FROM
(
    Select  
       catalogid, numitems, allitems - numitems ignoreditems 
    from 
        (
        select * from
        (
            select  
                i.catalogid, 
                sum(case when (ocardtype in ('PayPal','Sofort') 
                OR 
                ocardtype in ('mastercard','visa') and odate is not null) then numitems 
                else 0 end) numitems, 
                sum(numitems) allitems 
            from 
                orders
         ) o
        inner join
            items i 
        on 
            i.orderid=o.orderid
        inner join 
            products T1 
        on 
            T1.catalogid = i.catalogid
        group by 
            i.catalogid
        ) A
    ) X 
) B
INNER JOIN
SELECT * FROM
(
    SELECT 
        catalogId, 
        ProcessedSucssessfully = 
           STUFF((SELECT ', ' + CAST( b.orderid as varchar(10)) 
                  FROM oitems b JOIN orders o ON b.orderid = o.orderid 
                  WHERE b.catalogId = a.catalogId 
                  AND (o.ocardtype in ('PayPal','Sofort') OR o.ocardtype in  ('mastercard','visa') and o.odate is not null) 
                  FOR XML PATH('')), 1, 2, ''), 
                      NotProcessed = 
            STUFF((SELECT ', ' + CAST( c.orderid as varchar(10))

                   WHERE c.catalogid = a.catalogid 
                   AND (o.ocardtype in ('mastercard') OR o.ocardtype is null) and o.odate is null 
                   FOR XML PATH('')), 1, 2, '') 
    FROM 
        oitems a 
    GROUP BY 
        a.CatalogId
