Boas...

estou com dificuldades no seguinte, tenho um artigo em varias lojas com vários tamanhos. e queria atraves de um select receber qual a loja com menor artigo por tamanho.

A estrutura da tabela eu recebo o Artigo,loja, qtd/tamanho, ou seja...

Loja A Artigo XS S M L XL XXL

A KA 0 1 1 1 2 3

B KB 1 0 0 0 2 0

C KC 1 2 1 4 5 6

O que pretendia era atraves de um select saber qual a loja com menos quatidade por artigo, neste caso seria loja B no Artigo KB com apenas 2 tamanhos.

Eu queria um count do XS,S,M,L,XL,XLL que fosse inferior a 0

Viva,

Partilho dois métodos diferentes de realizares esta consulta, porém acho que os teus dados de exemplo não devem estar bem, porque presumo que possas ter o mesmo artigo em várias lojas, o que não foi o cenário que apresentaste:

-- Createing a temporary table variable and Inserting scenario data
DECLARE @tabela TABLE (Loja VARCHAR(10), Artigo VARCHAR(10), StockXS INT, StockS INT, StockM INT, StockL INT, StockXL INT, StockXXL INT)
INSERT INTO @tabela VALUES ('A', 'KA', 0, 1, 1, 1, 2, 3), ('B', 'KB', 1, 0, 0, 0, 2, 0), ('C', 'KC', 1, 2, 1, 4, 5, 6)

-- Just to check if data was correctly inserted
-- SELECT * FROM @tabela;

-- Method 1 (using inner queries)
SELECT TOP 1 Loja, Artigo, StockTotal
FROM
(
SELECT Loja, Artigo, StockXS + StockS + StockM + StockL + StockXL + StockXXL AS StockTotal FROM @tabela
) T ORDER BY StockTotal ASC;

-- Method 2 (using a common table expression)
WITH CTE (Loja, Artigo, StockTotal)
AS (SELECT Loja, Artigo, StockXS + StockS + StockM + StockL + StockXL + StockXXL AS StockTotal FROM @tabela)
SELECT TOP 1 * FROM CTE ORDER BY StockTotal ASC;

Boas Rechousa,

Sim, tens razão, o que pretendo é apurar um artigo por várias lojas. Reformulo abaixo a minha consulta.Essa querie ajuda, no entanto eu pretendia era saber qual o tamanho em tenho mais falta de stock, ou seja:

DECLARE @tabela TABLE (Loja VARCHAR(10), Artigo VARCHAR(10), StockXS INT, StockS INT, StockM INT, StockL INT, StockXL INT, StockXXL INT)
INSERT INTO @tabela VALUES ('A', 'KA', 0,0,0,1,2,2), ('B', 'KA', 0,0,1,1,1,1), ('C', 'KA', 0,0,1,1,0,0),('D', 'KA', 0,0,0,1,1,2),('E', 'KA', 0,0,0,0,2,2)
select * from  @tabela

Se repares na consulta acima pela método anterior ia aparecer a loja B com menor stock, só que no fundo eu pretendo é a loja E, tendo esta menos tamanhos disponiveis para venda.

Sim, de uma forma semelhante:

Repara que quer a loja C, quer a loja E têm 4 tamanhos sem stock.

No primeiro caso retorna a loja C (ordenado por StockTotal ASC). No segundo caso retorna a loja E (ordenado por StockTotal DESC)

DECLARE @tabela TABLE (Loja VARCHAR(10), Artigo VARCHAR(10), StockXS INT, StockS INT, StockM INT, StockL INT, StockXL INT, StockXXL INT)
INSERT INTO @tabela VALUES ('A', 'KA', 0,0,0,1,2,2), ('B', 'KA', 0,0,1,1,1,1), ('C', 'KA', 0,0,1,1,0,0),('D', 'KA', 0,0,0,1,1,2),('E', 'KA', 0,0,0,0,2,2)

-- Just to check if data was correctly inserted
-- SELECT * FROM @tabela;

-- Method 1 (using inner queries)
SELECT TOP 1 Loja, Artigo, TamanhosSemStock, StockTotal
FROM
(
SELECT Loja, Artigo,
   CASE StockXS WHEN 0 THEN 1 ELSE 0 END +
   CASE StockS WHEN 0 THEN 1 ELSE 0 END +
   CASE StockM WHEN 0 THEN 1 ELSE 0 END +
   CASE StockL WHEN 0 THEN 1 ELSE 0 END +
   CASE StockXL WHEN 0 THEN 1 ELSE 0 END +
   CASE StockXXL WHEN 0 THEN 1 ELSE 0 END AS TamanhosSemStock,
   StockXS + StockS + StockM + StockL + StockXL + StockXXL AS StockTotal FROM @tabela
) T ORDER BY TamanhosSemStock DESC, StockTotal ASC;

-- Method 2 (using a common table expression)
WITH CTE (Loja, Artigo, TamanhosSemStock, StockTotal)
AS (SELECT Loja, Artigo,
   CASE StockXS WHEN 0 THEN 1 ELSE 0 END +
   CASE StockS WHEN 0 THEN 1 ELSE 0 END +
   CASE StockM WHEN 0 THEN 1 ELSE 0 END +
   CASE StockL WHEN 0 THEN 1 ELSE 0 END +
   CASE StockXL WHEN 0 THEN 1 ELSE 0 END +
   CASE StockXXL WHEN 0 THEN 1 ELSE 0 END AS TamanhosSemStock,
   StockXS + StockS + StockM + StockL + StockXL + StockXXL AS StockTotal FROM @tabela)
SELECT TOP 1 * FROM CTE
   ORDER BY TamanhosSemStock DESC, StockTotal DESC;
