查詢選擇ID，名稱，使用子查詢的交貨成本

我想爲選擇customer id，cus_name，Total COD Orders作出一個查詢。我做了這兩個查詢，但這些查詢分別計算COD和NON COD。我如何使用子查詢進行單個查詢。查詢選擇ID，名稱，使用子查詢的交貨成本

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' 
FROM T_Acct_CompanyProfile c INNER JOIN 
    T_Inv_Order o 
    ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 1 
GROUP BY o.cust_id, c.name; 

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' 
FROM T_Acct_CompanyProfile c INNER JOIN 
    T_Inv_Order o 
    ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 0 
GROUP BY o.cust_id, c.name;

SQL SERVER 2008 –

由於查詢看起來非常相似，您可以使用union。因此，您的查詢變爲：

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' FROM T_Acct_CompanyProfile c 
INNER JOIN T_Inv_Order o ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 1 
group by o.cust_id, c.name 

UNION 

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' FROM T_Acct_CompanyProfile c 
INNER JOIN T_Inv_Order o ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 0 

group by o.cust_id, c.name

這會將兩個查詢合併到一個結果集中。有關Union關鍵字的更多信息，請參閱http://www.w3schools.com/sql/sql_union.asp。

我想這是你在爲你描述的代碼UNOIN，但這是給錯誤如下所列：「消息8120，級別16，狀態1，行列「T_Inv_Order。 cust_id'在選擇列表中無效，因爲它不包含在聚合函數或GROUP BY子句中。「 –

我做了一個編輯，包括第一組，因爲我不小心錯過了它。你是否在選擇的兩個部分中通過組來嘗試它？ –

只需使用條件彙總：

SELECT o.cust_id, UPPER(c.name), 
     SUM(CASE WHEN o.cod = 1 THEN 1 ELSE 0 END) as TotalCODOrders, 
     SUM(CASE WHEN o.cod = 0 THEN 1 ELSE 0 END) as TotalNonCODOrders 
FROM T_Acct_CompanyProfile c INNER JOIN 
    T_Inv_Order o 
    ON c.id = o.cust_id 
WHERE c.type_id = 1 
GROUP BY o.cust_id, c.name;

如果o.cod只對值0和1，那麼您可以使用快捷：

SELECT o.cust_id, UPPER(c.name), 
     SUM(o.cod = 1) as TotalCODOrders, 
     SUM(1 - o.cod) as TotalNonCODOrders,

使用聯盟

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' 
FROM T_Acct_CompanyProfile c INNER JOIN 
    T_Inv_Order o 
    ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 1 
GROUP BY o.cust_id, c.name; 

UNION 

SELECT o.cust_id, UPPER(c.name), count(o.order_no) AS 'Total COD Orders' 
FROM T_Acct_CompanyProfile c INNER JOIN 
    T_Inv_Order o 
    ON c.id = o.cust_id 
WHERE c.type_id = 1 AND o.cod = 0 
GROUP BY o.cust_id, c.name;

我會使用工會所有，因爲你不想要一個獨特的，我會添加'o.cod'能夠看到哪個計數是哪個 –

有條件聚合：

SELECT o.cust_id, 
     UPPER(c.name), 
     SUM(CASE WHEN o.cod = 1 THEN 1 ELSE 0 END) AS 'Total COD Orders', 
     SUM(CASE WHEN o.cod = 0 THEN 1 ELSE 0 END) AS 'Total non COD Orders' 
FROM T_Acct_CompanyProfile c 
INNER JOIN T_Inv_Order o ON c.id = o.cust_id 
WHERE c.type_id = 1 
group by o.cust_id, c.name
