Sql 使用子查询查询Select Id、名称、交货成本

我想做一个查询来选择

客户id

，

客户名称

，

总COD订单

。我做了这两个查询，但是这些查询分别计算

COD

和

非COD

。如何使用子查询进行单个查询

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;

---

由于查询似乎非常相似，您可以使用

联合

。因此，您的查询变成：

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

---

这将把两个查询合并成一个结果集。有关Union关键字的更多信息，请参阅。

只需使用条件聚合：

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;

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

如果

o.cod

仅接受值0和1，则可以使用快捷方式：

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

我会使用union all，因为你不想要一个独立的，我会添加

o.cod
