将复杂的 count() 查询结果插入表

Question

• 注意：这个问题以前被过度简化了；附加问题是为了更好地理解我的问题

我有一家公司的发货数据表，称为 t_shipment。 （部分）标头为 acc_num、type_of_business、contract_exception、payment_status 等。

我需要为其他部门的工作做一个总结表。因此，我使用 CREATE TABLE 创建了一个新表 ship_recap。

CREATE TABLE ship_recap
(vol_lumber(int), vol_oil(int);)

然后我需要回顾一下从 t_shipment 到 ship_recap 的相关数据。我用过

 INSERT INTO ship_recap (vol_lumber)
 SELECT COUNT(acc_num) from t_shipment WHERE type_of_business = 'LMB' and (contract_exception = 'VALID' OR payment_status IS NOT NULL)
 INSERT INTO ship_recap (vol_oil)
 SELECT COUNT(acc_num) from t_shipment where type_of_business = 'OIL' and (contract_exception = 'VALID' OR payment_status IS NOT NULL);)

它跑了，但结果是：

 ____________________
|vol_lumber| vol_oil |
----------------------
|   150    |   NULL  |
|   NULL   |   230   |
----------------------

但我希望他们是：

 ____________________
|vol_lumber| vol_oil |
----------------------
|   150    |   230   |
----------------------

我尝试过使用

INSERT INTO ship_recap (vol_lumber, vol_oil)
(SELECT COUNT(acc_num) from t_shipment WHERE type_of_business = 'LMB' and (contract_exception = 'VALID' OR payment_status IS NOT NULL),
SELECT COUNT(acc_num) from t_shipment where type_of_business = 'OIL' and (contract_exception = 'VALID' OR payment_status IS NOT NULL);)

以及相同逻辑的排列方式（例如将逗号改为分号，或者去掉括号），但每次都返回语法错误。

结果/回顾表可能有多达 20 多个标题，其他查询也可能稍微复杂一些。 我需要一种方法来正确地将 SELECT/COUNT-ed 数据插入到回顾表中，并将它们保持在一行中。

编辑：根据 Reno 的建议，我尝试了这个

 CREATE TABLE ship_recap (vol_OIL int,vol_LUM int,vol_BEV int,processed_OIL int,processed_LUM int,processed_BEV int);
 INSERT INTO ship_recap (vol_OIL, vol_LUM, vol_BEV, processed_OIL, processed_LUM, processed_BEV)
 SELECT
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)) FROM t_shipment;

一旦我更正了缺少的参数和括号，它就起作用了。

试试下面的sql，可能对你有帮助；）

 CREATE TABLE ship_recap (vol_OIL int,vol_LUM int,vol_BEV int,processed_OIL int,processed_LUM int,processed_BEV int);
 INSERT INTO ship_recap (vol_OIL, vol_LUM, vol_BEV, processed_OIL, processed_LUM, processed_BEV)
 SELECT
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12', 1, NULL)),
  COUNT(IF(type_of_business = 'OIL' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'LUM' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)),
  COUNT(IF(type_of_business = 'BEV' and process_date = '2016-05-12' and (contract_exception = ‘VALID’ OR payment_status IS NOT NULL), 1, NULL)) FROM t_shipment;
