mysql - 将复杂的 count() 查询结果插入表中

Question

• 注意:这个问题之前被过于简单化了；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，名为 t_shipment。 (部分) header 包括 acc_num、type_of_business、contract_exception、 payment_status 等。

我需要为其他部门的工作制作一个回顾表。因此，我使用 CREATE TABLE 创建一个新表 Ship_recap。

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

然后我需要将t_shipment中的相关数据重述到ship_recap中。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);)

它运行了，但结果是:

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

但我希望它们是:

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

我尝试使用

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(例如将逗号改为分号，或去掉括号)，但每次都返回语法错误。

结果/回顾表可能有多达 20 个以上的 header ，其他查询也可能会变得稍微复杂一些。 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留在一行中。

编辑:根据里诺的建议，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;

一旦我更正了丢失的参数和括号，它就起作用了。

尝试下面的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;
